Tesla Roadster (first generation)

March 04, 2023

For Tesla's second sports car or its second generation, see Tesla Roadster (second generation).

The Tesla Roadster is a battery electric vehicle (BEV) sports car, based on the Lotus Elise chassis, that was produced by the electric car firm Tesla Motors (now Tesla, Inc.) in California from 2008 to 2012. The Roadster was the first highway legal serial production all-electric car to use lithium-ion battery cells and the first production all-electric car to travel more than 320 kilometres (200 mi) per charge.[7] It is also the first production car to be launched into deep space, carried by a Falcon Heavy rocket in a test flight on February 6, 2018.

Tesla sold about 2,450 Roadsters in over 30 countries,[8][9][10] and most of the last Roadsters were sold in Europe and Asia during the fourth quarter of 2012.[11] Tesla produced right-hand-drive Roadsters from early 2010.[12] The Roadster qualified for government incentives in several nations.[13][14]

According to the U.S. EPA, the Roadster can travel 393 kilometres (244 mi) on a single charge[15] of its lithium-ion battery pack, and can accelerate from 0 to 97 km/h (0 to 60 mph) in 3.7 or 3.9 seconds depending on the model. It has a top speed of 201 km/h (125 mph). The Roadster's efficiency, as of September 2008, was reported as 120 MPGe (2.0 L/100 km). It uses 135 Wh/km (21.7 kWh/100 mi) battery-to-wheel, and has an efficiency of 88% on average.[16]

History

Prototypes of the car were officially revealed to the public on July 19, 2006, in Santa Monica, California, at a 350-person invitation-only event held in Barker Hangar at Santa Monica Airport.[17]

The San Francisco International Auto Show, held on November 18–26, 2006, was the Tesla Roadster's first auto show.[citation needed]

It was featured in Time in December 2006 as the recipient of the magazine's "Best Inventions 2006—Transportation Invention" award.[18] The first "Signature One Hundred" set of fully equipped Roadsters sold out in less than three weeks, the second hundred sold out by October 2007 and general production began on March 17, 2008.[citation needed]

The first Tesla Roadster was delivered in February 2008 to Tesla co-founder, chairman and product architect Elon Musk. The company produced 500 similar vehicles through June 2009. In July 2009, Tesla began production of its 2010 model-year Roadster—the first major product upgrade.[19] Simultaneously, Tesla began producing the Roadster Sport, the first derivative of Tesla's proprietary, patented powertrain. The car accelerates from 0 to 97 km/h (0 to 60 mph) in 3.7 seconds, compared to 3.9 seconds for the standard Roadster. Changes for the 2010 model-year cars included:[20]

  • An upgraded interior and push-button gear selector, including "executive interior" of exposed carbon fiber and premium leather, and clear-coat carbon fiber body accents.
  • Locking, push-button glove box wrapped in leather.
  • A centrally mounted video display screen to monitor real-time data, including estimated range, power regenerated, and the number of barrels of oil saved. This screen is visible to the driver and passenger.
  • Adjustable, custom-tuned suspension. The shock absorbers' response and anti-sway bars are manually adjustable.
  • More powerful and immediate heating, ventilation and air-conditioning.
  • More efficient motor and hand-wound stator. The increase in efficiency allows the motor to deliver higher peak power.
  • A suite of sound-deadening measures to dramatically reduce noise, vibration and harshness. For instance, engineers added pellets to a member of the chassis side rail. These pellets expand by 50 times original volume during the adhesive heating cycle to eliminate rattles.

All of these features, except for the motor, were available either as standard or as add-on option for the non-sport model.

Beginning mid-March 2010, Tesla, in an effort to show off the practicality of its electric cars, sent one of its Roadsters around the world. Starting at the Geneva auto show, the Roadster completed its journey upon its arrival in Paris on September 28, 2010.[21]

In July 2010, Tesla introduced the "Roadster 2.5", the latest update of the Roadster.[22] New features in Roadster 2.5 include:

  • A new look, which included a new front fascia with diffusing vents, and rear diffuser reflecting the future of Tesla design
  • Directional forged wheels available in both silver and black
  • New seats with improved comfort, larger more supportive bolsters and a new lumbar support system
  • Power control hardware that enables spirited driving in exceptionally hot climates
  • An optional 7" touchscreen display with back-up camera
  • Improved interior sound reduction including new front fender liner material to make the cabin quieter

At the time, the US$112,000 Roadster was the most expensive single prize ever offered, though not won, on The Price Is Right, in a playing of Golden Road on April 22, 2010, for Earth Day.[23]

A Roadster was used as a promotional tool for a wind power electricity company in 2012.[24][25]

Tesla produced the Roadster until January 2012, when its supply of Lotus gliders ran out, as its contract with Lotus Cars for 2,500 gliders expired at the end of 2011.[9][26][27][28] Tesla stopped taking orders for the Roadster in the U.S. market in August 2011.[29][30] The next generation will not be based on the Lotus gliders but instead on a shortened version of the architecture developed for the Tesla Model S.[31][32] Featuring new options and enhanced components, the 2012 Tesla Roadster was sold in limited numbers only in Europe, Asia, and Australia. Tesla's U.S. exemption for not having special two-stage passenger airbags expired for cars made after the end of 2011 so the last Roadsters could not be sold in the American market.[33][34] Fifteen Final Edition Roadsters were produced to close the manufacturing cycle of Tesla's first electric car.[35]

Tesla announced an optional upgrade to current Roadsters, the Roadster 3.0, in December 2014. It offered a new battery pack from LG Chem[36] increasing capacity by 50% to 70 kWh, a new aero kit designed to reduce drag, and new tires with lower rolling resistance.[37][38] As of December 2020, the Roadster 3.0 upgrade package has been removed from Tesla's website.[citation needed]

Development

See also: History of Tesla Inc.

The Roadster was developed by Tesla to mass-produce AC Propulsion's tzero concept car.

After Martin Eberhard sold NuvoMedia to TV Guide, he wanted a sports car with high mileage, but could not find one. His battery experience with the Rocket eBook inspired him to develop an electric car.[39] The production idea was conceived by Eberhard and Marc Tarpenning who incorporated Tesla Motors in Delaware on July 1, 2003, to pursue the idea commercially.[40] South African-born entrepreneur Elon Musk took an active role within the company starting in 2004, including investing US$7.5 million, overseeing Roadster product design from the beginning, and greatly expanding Tesla's long-term strategic sales goals by using the sports car to fund the development of mainstream vehicles.[41][42] Musk became Tesla's chairman of the board in April 2004 and helped recruit JB Straubel as chief technology officer in March 2004.[43] Musk received the Global Green 2006 product design award for the design of the Tesla Roadster, presented by Mikhail Gorbachev,[44] and he received the 2007 Index Design award for the design of the Tesla Roadster.[45]

Tzero – the proof of concept Tesla

Before Tesla had developed the Roadster's proprietary powertrain, they borrowed an AC Propulsion Tzero vehicle as a test mule and converted from lead acid AGM batteries to lithium ion cells, which substantially increased the range, reduced weight, and boosted 0–60 mph (0–97 km/h) performance. Tesla then licensed AC Propulsion's EV power system design and reductive charging patent, which covers integration of the charging electronics with the inverter, thus reducing mass, complexity, and cost. Tesla, however, was dissatisfied with how the motor and transmission worked in the chassis.[46] Tesla then designed and built its own power electronics, motor, and other drivetrain components that incorporated this licensed technology from AC Propulsion.[47][48][49] Given the extensive redevelopment of the vehicle, Tesla Motors no longer licenses any proprietary technology from AC Propulsion. The Roadster's powertrain is unique.[50]

On July 11, 2005, Tesla and British sports car maker Lotus entered an agreement about products and services based on the Lotus Elise, where Lotus provided advice on designing and developing a vehicle as well as producing partly assembled vehicles,[51] and amended in 2009,[52] helped with basic chassis development. The Roadster has a parts overlap of roughly 6% with the Lotus Elise,[53] a 2-inch-longer wheelbase, and a slightly stiffer chassis according to Eberhard.[54] Tesla's designers chose to construct the body panels using resin transfer molded carbon fiber composite to minimize weight; this choice makes the Roadster one of the least expensive cars with an entirely carbon fiber skin.[53]

Several prototypes of the Tesla Roadster were produced from 2004 through 2007. Initial studies were done in two "test mule" vehicles based on Lotus Elises equipped with all-electric drive systems. Tesla then built and tested ten engineering prototypes (EP1 through EP10) in late 2006 and early 2007, which led to many minor changes. Next, Tesla produced at least 26 validation prototypes, which were delivered beginning in March 2007.[55] These final revisions were endurance and crash tested in preparation for series production.[citation needed]

In August 2007, Martin Eberhard was replaced by an interim CEO, Michael Marks.[56] Marks accepted the temporary position while a recruitment was undertaken. In December 2007, Ze'ev Drori became the CEO and president of Tesla. In October 2008, Musk succeeded Drori as CEO. Drori became vice chairman and left the company in December. In January 2008, the U.S. National Highway Traffic Safety Administration (NHTSA) announced that it would grant a waiver of the advanced air bag rule[57] noting that the Tesla Roadster already includes standard air bags; similar waivers have been granted to many other small volume manufacturers as well, including Lotus, Ferrari, and Bugatti.[58][59][60] Tesla delivered its first production car in February 2008 to Musk.

Tesla announced in early August 2009 that Roadster sales had resulted in overall corporate profitability for the month of July 2009, earning US$1 million on revenue of US$20 million.[61]

Tesla, which signed a production contract with Group Lotus in 2007 to produce "gliders" (complete cars minus electric powertrain) for the Roadster, announced in early 2010 that Roadster production would continue until early 2012. Starting one year prior to the end of the contract, Tesla put a hiatus on new orders to allow time for tooling changes at Lotus's assembly plant in the UK.[62]

Several years later in 2018, Musk would go on to say that using the Lotus Elise as a base for the Roadster was a poor strategy. This is because the Elise was incompatible with the intended AC Propulsion technology, and was modified so extensively only 7% of the original Elise remained in the final production version.[63]

Production

 
Interior of Roadster 2.5 from July 2010

Tesla's cumulative production of the Roadster reached 1,000 cars in January 2010.[64] The Roadster is considered an American car though many carry a Vehicle Identification Number beginning with the letter "S", which is the designation for the United Kingdom.[65] Some, however, carry a number starting with "5" appropriate to the US. Parts were sourced from around the world. The body panels came from French supplier Sotira. These were sent from France to Hethel, U.K., where Tesla contracted with Lotus to build the Roadster's unique chassis.[66][67] The Roadster shares roughly 6% of its components with the Lotus Elise; shared components include the windshield, airbags, some tires, some dashboard parts, and suspension components. The Roadster's single-speed gearbox was made in Detroit to Tesla's specifications by Auburn Hills, Michigan-based supplier BorgWarner. Brakes and airbags were made by Siemens in Germany, and some crash testing was conducted at Siemens as well.[68] 30–40% of components were sourced from Taiwan.[69]

For Roadsters bound for customers in North America, the chassis was then sent to Menlo Park, California, for final assembly, and for Roadsters bound for customers in Europe or elsewhere outside of North America, the chassis was sent to a facility at Wymondham near Hethel, for final assembly. At these final assembly locations, Tesla employees installed the entire powertrain, which consisted of the battery pack, power electronics module, gearbox and motor. Tesla also performed rigorous "pre-delivery inspection" on every car before customers took ownership.[citation needed]

Tesla ordered 2,500 gliders from Lotus, which ended supplies in December 2011 when their contract expired.[27][28] Tesla ended production of the Roadster in January 2012.[26]

Timeline

Subsequent to completion of production car number one at Hethel, the company announced problems with transmission reliability. The development transmission, with first gear enabled to accelerate 0 to 97 km/h (0 to 60 mph) in 4 seconds, was reported to have a life expectancy of as low as only a few thousand miles. Tesla's first two transmission suppliers were unable to produce transmissions, in quantity, that could withstand the gear-shift requirements of the high torque, high rpm electric motor. In December 2007, Tesla announced plans to ship the initial Roadsters with the transmissions locked into second gear to provide 0 to 97 km/h (0 to 60 mph) acceleration in 5.7 seconds. The first production car was not delivered with this interim solution; P1 has both transmission gears enabled. According to the plan, the initial transmissions were to be swapped out under warranty when the finalized transmission, power electronics module (PEM), and cooling system became available. The EPA range of the car was also restated downward from 394 to 356 km (245 to 221 mi). The downward revision was attributed to an error in equipment calibration at the laboratory that conducted the original test.[70][71][72]

  • During the first two months of production, Tesla produced a total of three Roadsters (P3/VINF002, P4/VINF004, and P5/VINF005). Production car # 1 (P1) and P2 were built prior to the start of regular series production, which began March 17, 2008.[73]
  • By September 10, 2008, Tesla had delivered 27 of the cars to customers. It was also reported that a newer, better transmission had been developed and that production of the car was hoped to reach 20 per week by December 2008, and 40 per week by March 2009.[74] Over the next 20 days, however, only three more cars had been delivered to customers, which brought the total to 30 as of September 30, 2008.[75]
  • By November 19, 2008, more than 70 of the cars had been delivered to customers.[76]
  • By December 9, 2008, the 100th car had been delivered.[77]
  • By February 11, 2009, 200 Roadsters had been produced.[78]
  • By April 2, 2009, 320 Roadsters had been delivered.[79]
  • In May 2009, Tesla issued a safety recall for all 345 of its Roadsters that were manufactured before April 22, 2009. Tesla sent technicians to customers' homes to tighten the rear, inner hub flange bolts. Tesla told customers that without this adjustment, the driver could lose control of the car and crash. The problem originated at the Lotus assembly line that built the Roadster and Lotus also recalled some of its own vehicles. Tesla reminded customers that millions of cars are recalled every year.[80][81]
  • By the end of May 2009, the 500th Roadster had been delivered.[82]
  • Tesla made its first profit ever in July 2009, when it shipped 109 vehicles, the most in a single month at that time.[83]
  • By September 15, 2009, 700 Roadsters had been delivered.[84]
  • Tesla announced on January 13, 2010, that it had produced its 1,000th Roadster. The company had delivered vehicles to customers in 43 states and 21 countries worldwide.[85] In 2009 Tesla began taking orders from customers in Canada, and Canadian deliveries began in February 2010.[86][87]
  • In January 2010, Tesla began producing its first right-hand-drive Roadsters for the UK and Ireland. The 2010 model-year right-hand-drive Roadster included a suite of unique noise-reduction materials and an upgraded sound system. The Roadster started at £86,950 and cost about 1.5p per mile.
  • On January 29, 2010, in a Form S-1 filing of its preliminary prospectus with the U.S. Securities and Exchange Commission, the company stated that it would halt production of the Roadster in 2011 and replace it with a new model that would not be introduced until 2013 at the earliest: "...we do not plan to sell our current generation Tesla Roadster after 2011 due to planned tooling changes at a supplier for the Tesla Roadster, and we do not currently plan to begin selling our next-generation Tesla Roadster until at least one year after the launch of the Model S, which is not expected to be in production until 2012..."[88][89][90] The Model S was released in June 2012.[91]
  • On March 16, 2010, Tesla announced that it had "negotiated agreements with key suppliers that will increase total Roadster production by 40 percent and extend sales into 2012",[92] also indicating that it would expand into the Asian and Australian markets by 2011.[92]
  • On December 2, 2010, Tesla had delivered more than 1,400 Roadsters.[93]
  • On September 28, 2011, Tesla delivered its 100th Roadster in Switzerland.[94]
  • Production ended in January 2012 and was no longer available for sale the U.S. after December 2011.[26]
  • More than 2,418 units were sold worldwide through September 2012. The remaining cars were available for sale only in Europe and Asia.[9][10] Most of the remaining Roadsters were sold during the fourth quarter of 2012.[11][35][95]
  • In 2015, it was announced that a successor to the Roadster would debut in 2019.[96]
  • In 2016, Tesla began selling a battery upgrade from 53 kWh to 80 kWh.[97][98][99]
  • In 2017, it was announced that a successor to the Roadster would debut in 2020.[100]

Special final edition

Tesla produced a special edition of 15 Final Edition Roadsters to close the production cycle of the electric car. The 15 special-edition cars were sold in each of the three sales regions, North America, Europe and Asia, and five units were allocated to each. The Final Edition Roadster did not have any performance modifications, but featured sporting atomic red paint, a duo of dark silver stripes on its hood and rear clamshell, and exclusive anthracite aluminum wheels.[35]

Specifications

Motor

 
 
Tesla Roadster with hood and trunk open

The Roadster is powered by a 3-phase, 4-pole, induction electric motor with a maximum output power of 185 kW (248 hp).[101] Its maximum torque of 200 lb⋅ft (270 N⋅m) is immediately available and remains constant from 0 to 6,000 rpm;[102] nearly instantaneous torque is a characteristic of electric motors and offers one of the biggest performance differences from internal combustion engines. The motor is air-cooled and does not need a liquid cooling system.[103][104]

The Sport model introduced during the Jan 2009 Detroit Auto Show includes a motor with a higher density, hand-wound stator that produces a maximum of 288 hp (215 kW).[105] Both motors are designed for rotational speeds of up to 14,000 rpm, and the regular motor delivers a typical efficiency of 88%[16] or 90%; 80% at peak power. It weighs less than 70 pounds (32 kg).[106]

Transmission

Starting in September 2008 Tesla selected BorgWarner to manufacture gearboxes and began equipping all Roadsters with a single speed, fixed gear gearbox (8.2752:1) with an electrically actuated parking pawl mechanism and a mechanical lubrication pump.[15]

The company previously worked with several companies, including XTrac and Magna International, to find the right automatic transmission, but a two-gear solution proved to be too challenging. This led to substantial delays in production. At the "Town Hall Meeting" with owners in December 2007, Tesla announced plans to ship the initial 2008 Roadsters with their interim Magna two-speed direct shift manual transmissions locked into second gear, limiting the performance of the car to less than what was originally stated (0 to 97 km/h (0 to 60 mph) in 5.7 seconds instead of the announced 4.0 seconds). Tesla also announced it would upgrade those transmissions under warranty when the final transmission became available.[70][72][107] At the "Town Hall Meeting" with owners on January 30, 2008, Tesla Motors described the planned transmission upgrade as a single-speed gearbox with a drive ratio of 8.27:1 combined with improved electronics and motor cooling that retain the acceleration from 0 to 60 mph (0 to 97 km/h) in under 4 seconds and an improved motor limit of 14,000 rpm to retain the 201 km/h (125 mph) top speed.[108] The upgraded system also improved the maximum torque from 270 to 380 N⋅m (200 to 280 lb⋅ft) and improves the Roadster's quarter mile times.[citation needed]

Gear selector

In the interior the gear selector is similar to a push-button automatic with buttons labeled P, R, N and D while some earlier models have a gear lever similar to that in cars with manual transmission.[citation needed]

Performance

The Roadster's 0 to 97 km/h (0 to 60 mph) acceleration time is 3.9 seconds for the Standard model and 3.7 seconds for the 2010 V2.5 Sport, which Motor Trend confirmed in the first independent, instrumented testing of the V2.5 Sport model. The magazine also recorded a 0-to-1⁄4-mile (0.00 to 0.40 km) time of 12.6 seconds at 165.1 km/h (102.6 mph).[109] Tesla said the top speed is electronically limited to 201 km/h (125 mph). Tesla claims it has a weight of 1,305 kg (2,877 lb), a drag coefficient of Cd=0.35–0.36[110] and a rolling resistance of Crr=0.011.[38]

Tesla began delivering the higher performance version of the Roadster in July 2009. The Roadster Sport has adjustable dampers and a new hand-wound motor, capable of 0 to 97 km/h (0 to 60 mph) in 3.7 seconds.[111] Scotty Pollacheck, a high-performance driver for Killacycle, drove a 2010 Tesla Roadster Sport at the Wayland Invitational Drag Race in Portland, Oregon, in July 2009. He did a quarter-mile (~400 m) in dry conditions in 12.643 seconds, setting a new record in the National Electric Drag Racing Association among the SP/A3 class of vehicles.[112] The EPA combined range (specifying distance traveled between charges) measured in February 2008 for early production Roadsters was 372 km (231 mi) city, 360 km (224 mi) highway, and 365 km (227 mi) combined (city/highway).[113] In August 2008, additional testing with the newer Powertrain 1.5 resulted in an EPA combined range of 393 km (244 mi).[15] The vehicle set a new distance record when it completed the 388-kilometre (241 mi) Rallye Monte Carlo d'Energies Alternatives with 58 km (36 mi) left on the charge.[114] A Roadster drove around the world (although flying as cargo over oceans) in 2012,[115] and repeated it in 80 days with other electric cars in 2016.[116]

Simon Hackett and Emilis Prelgauskas broke the distance record for an electric vehicle, driving 501 km (311 mi) from Alice Springs to Marla, South Australia, in Simon's Tesla Roadster. The car had about 4.8 km (3.0 mi) of range left when the drive was completed.[117]

Battery system

Tesla refers to the Roadster's battery pack as the Energy Storage System or ESS. The 450 kg (992 lb) ESS contains 6,831 lithium ion cells arranged into 11 "sheets" connected in series; each sheet contains 9 "bricks" connected in series; each "brick" contains 69 cells connected in parallel (11S 9S 69P). The cells are of the 18650 form factor commonly found in laptop batteries. Sources disagree[118] on the exact type of Li-Ion cells—GreenCar says lithium cobalt oxide (LiCo), while researchers at DTU/INESC Porto state lithium manganese oxide (LMO).[119] LiCo has higher reaction energy during thermal runaway than LMO.[120]

The pack is designed to prevent catastrophic cell failures from propagating to adjacent cells (thermal runaway), even when the cooling system is off.[121] Coolant is pumped continuously through the ESS both when the car is running and when the car is turned off if the pack retains more than a 90% charge. The coolant pump draws 146 watts.[122][123][124] The cooling and battery management system keeps the temperatures and voltages within specific limits.[125]

 
Charging unit

A full recharge to 53 kWh requires about 3½ hours using the High Power Connector, which supplies 70-amp, 240-volt electricity.[126][127]

Tesla said in February 2009 that the ESS had expected life span of seven years/160,000 km (100,000 mi), and began selling pre-purchase battery replacements for about one third of the battery's price today, with the replacement to be delivered after seven years. Tesla says the ESS retains 70% capacity after five years and 80,000 km (50,000 mi) of driving, assuming 16,000 km (10,000 mi) driven each year. A July 2013 study found that after 160,000 km (100,000 mi), Roadster batteries still had 80%–85% capacity and the only significant factor is mileage (not temperature).[128]

Tesla announced plans to sell the battery system to TH!NK and possibly others through its Tesla Energy Group division. The TH!NK plans were put on hold by interim CEO Michael Marks in September 2007.[129][130][131] TH!NK now obtains its lithium-ion batteries from Enerdel.[citation needed]

Recharging

The Roadster uses a proprietary charging connector, although Tesla sells a mobile adapter that enables recharging with an SAE J1772-2009 connector.[6] The vehicle can be recharged using:[132]

  • A wall-mounted 208–240 V, 70 A maximum current Home Connector. This appears to be an OEM version of the TS-70 charging station from ClipperCreek.[133]
  • A portable 120–240 V, 40 A maximum current Universal Mobile Connector cable that can plug into a NEMA 14–50 receptacle and other 240 V receptacles using adapters.
  • A portable 120 V, 15 A maximum current Spare Mobile Connector cable that plugs into a standard North American domestic socket.

Charging times vary depending on the ESS's state-of-charge, the available voltage, and the available circuit breaker amp rating (current). In a best case scenario using a 240 V charger on a 90 A circuit breaker, Tesla documents a recharging rate of 90 km (56 mi) of range for each hour charging; a complete recharge from empty would require just under four hours. The slowest charging rate using a 120 V outlet on a 15 A circuit breaker would add 8.0 km (5 mi) of range for each hour charging; a complete recharge from empty would require 48 hours.[134]

Energy efficiency

In June 2006, Tesla reported the Roadster's battery-to-wheel efficiency as 110 Wh/km (17.7 kWh/100 mi) on an unspecified driving cycle—either a constant 97 km/h (60 mph)) or SAE J1634 test—and stated a charging efficiency of 86% for an overall plug-to-wheel efficiency of 128 Wh/km (20.5 kWh/100 mi).[49][139][140]

 
Evolution of the Roadster's plug-to-wheel efficiency (smaller values indicate better efficiency)

In March 2007, Tesla reported the Roadster's efficiency on the EPA highway cycle as "135 mpg [U.S.] equivalent, per the conversion rate used by the EPA" or 133 Wh/km (21.5 kWh/100 mi) battery-to-wheel and 155 Wh/km (24.9 kWh/100 mi) plug-to-wheel.[141][142][143][144] The official U.S. window sticker of the 2009 Tesla Roadster showed an EPA rated energy consumption of 32 kWh/100 mi in city and 33 kWh/100 mi on the highway, equivalent to 105 mpg city and 102 mpg highway.[145][146] The EPA rating for on board energy efficiency for electric vehicles before 2010 was expressed as kilowatt-hour per 100 miles (kWh/100 mi).[147][148] Since November 2010, with the introduction of the Nissan Leaf and the Chevrolet Volt, EPA began using a new metric, miles per gallon gasoline equivalent (MPGe). The Roadster was never officially rated by the EPA in MPGe.[149][150]

In August 2007, Tesla dynamometer testing of a validation prototype on the EPA combined cycle yielded a range of 356 km (221 mi) using 149 Wh/km (23.9 kWh/100 mi) battery-to-wheel and 209 Wh/km (33.6 kWh/100 mi) plug-to-wheel.[70][151]

In February 2008, Tesla reported improved plug-to-wheel efficiency after testing a validation prototype car at an EPA-certified location. Those tests yielded a range of 350 km (220 mi) and a plug-to-wheel efficiency of 199 Wh/km (32.1 kWh/100 mi).[152][153]

In August 2008, Tesla reported on testing with the new, single-speed gearbox and upgraded electronics of powertrain 1.5, which yielded an EPA range of 393 km (244 mi) and an EPA combined cycle, plug-to-wheel efficiency of 174 Wh/km (28 kWh/100 mi).[154]

In 2007, the Roadster's battery-to-wheel motor efficiency was reported as 88%[16] to 90% on average and 80% at peak power.[155] For comparison, internal combustion engines have a tank-to-wheel efficiency of about 15%.[156] Taking a more complete picture including the cost of energy drawn from its source, Tesla reports that their technology, assuming electricity generated from natural gas-burning power plants, has a high well-to-wheel efficiency of 1.14 km per megajoule, compared to 0.202 km/MJ for gasoline-powered sports cars, 0.478 km/MJ for gasoline-powered commuter cars, 0.556 km/MJ for hybrid cars, and 0.348 km/MJ for hydrogen fuel cell vehicles.[140][157]

Petroleum-equivalent efficiency

See also: electric car § Comparison with internal combustion engine vehicles (ICEVs)

As the Roadster does not use gasoline, petroleum efficiency (MPG, L/100 km) cannot be measured directly but instead is calculated using one of several equivalent methods:

A number comparable to the typical Monroney sticker's "pump-to-wheel" fuel efficiency can be calculated based on regulations from the DOE and its energy content for a U.S. gallon of gasoline of 33,705 Wh⁄gal (also called the Lower Heating Value (LHV) of gasoline):[158][159]

 

For CAFE regulatory purposes, the DOE's full petroleum-equivalency equation combines the primary energy efficiencies of the US electric grid and the well-to-pump path with a "fuel content factor" that quantifies the value of conservation, scarcity of fuels, and energy security in the US.[158] This combination yields a factor of 82,049 Wh⁄gal in the above equation and a regulatory fuel efficiency of 293 mpggeCAFE.

Recharging with electricity from the average US grid, the factor changes to 12,307 Wh⁄galUS[158] to remove the "fuel content factor" = 1⁄0.15 and the above equation yields a full-cycle energy-equivalency of 44.0 mpgge full-cycle. For full-cycle comparisons, the sticker or "pump-to-wheel" value from a gasoline-fueled vehicle must be multiplied by the fuel's "well-to-pump" efficiency; the DOE regulation specifies a "well-to-pump" efficiency of 83% for gasoline.[158] The Prius's sticker[160] 46 mpg‑US (5.1 L/100 km; 55 mpg‑imp), for example, converts to a full-cycle energy-equivalent of 38.2 mpgfull-cycle.[158]

Recharging with electricity generated by newer, 58% efficiency CCGT power plants,[161] changes the factor to 21,763 Wh⁄gal[158] in the above equation and yields a fuel efficiency of 77.7 mpgge.

Recharging with non-fossil fuel electricity sources such as hydroelectric, solar power, wind or nuclear, the petroleum equivalent efficiency can be even higher as fossil fuel is not directly used in refueling.[162]

Service

Whereas vehicles with internal combustion engines require more frequent service for oil changes and routine maintenance on engine components and other related systems, Tesla's website recommends the owner bring the vehicle in for service "once a year or every 12,000 miles".[163] For other concerns with vehicles, Tesla created a "mobile service unit" that dispatches company-trained technicians to customers' homes or offices in case the owner is experiencing problems. Tesla charges the customer according to the distance the service unit needs to travel: one US dollar per mile roundtrip with a 100-dollar minimum.[163] Technicians drive company vans equipped with numerous tools and testing equipment to do "in the field" repairs, enhancements and software upgrades. Tesla debuted this "house call" approach in the spring of 2009, when the company announced a recall due to a manufacturing problem in the Lotus assembly plant, which also affected the Lotus Elise and other models from the British sports car maker.[164]

The first Tesla service center, in Los Angeles, California, was opened on Santa Monica Boulevard on May 1, 2008.[165] Tesla publicly opened their second showroom and service area in Menlo Park, California on July 22, 2008. The Menlo Park location is also the final assembly area for Tesla Roadsters. Tesla also operates service centers in New York City, Miami, Chicago, and Seattle.[citation needed]

In 2007, Tesla announced plans to build additional service centers over the following few years to support sales of its next vehicle, the Model S sports sedan. This included an additional 15 service centers in United States major metropolitan locations.[166] Possible locations for sales and service locations in Europe were announced in a letter to customers in May 2008.[167]

Recalls

As of May 2017, Tesla has issued two product safety recalls for the Roadster.[168]

In May 2009, Tesla issued a recall for 345 Roadsters manufactured before April 22, 2009. Tesla sent technicians to customers' homes to tighten the rear, inner hub flange bolts. Using wording from the National Highway Traffic and Safety Administration, Tesla told customers that without this adjustment, the driver could lose control of the car.[169] The problem originated at the Lotus assembly line, where the Roadster glider was built. Lotus also recalled some Elise and Exige vehicles for the same reason.[170]

On October 1, 2010, Tesla issued a second product safety recall in the US affecting 439 Roadsters. The recall involved the 12V low-voltage auxiliary cable from a redundant back-up system. The recall followed an incident where the low voltage auxiliary cable in a vehicle chafed against the edge of a carbon fiber panel, causing a short, smoke and a possible fire behind the right front headlamp. This issue was limited to the 12V low-voltage auxiliary cable and did not involve the main battery pack or main power system.[171]

Reviews

Tesla Roadster reviews can be grouped in two main categories: older reviews of "validation prototypes" (2006–2008), before Tesla began serial production and customer deliveries, and reviews on cars in serial production (2008–2010).[citation needed]

The global online auto review site Autoguide.com tested Tesla's fourth-generation car in October 2010. Autoguide editor Derek Kreindler said "The Tesla Roadster 2.5 S is a massively impressive vehicle, more spacecraft than sports car. Theories like global warming, peak oil and rising oil prices should no longer bring heart palpitations to car fans. The Tesla shows just how good zero-emissions "green" technology can be. Quite frankly, getting into a normal car at the end of the test drive was a major letdown. The whirr of the engine, the shove in the backside and the little roadster that seems to pivot around you is replaced by a grunting, belching, feedback-free driving experience". He continues on that "but for a $100,000 car, it could use some work" complaining of purposefully cheap work.[172]

In the March 2010 print edition of British enthusiast magazine EVO (p. 120), editor Richard Meaden was the first to review the all-new right-hand-drive version of the Roadster. He said the car had "serious, instantaneous muscle". "With so much torque from literally no revs the acceleration punch is wholly alien. Away from traffic lights you'd murder anything, be it a 911 Turbo, GT-R or 599, simply because while they have to mess about with balancing revs and clutch, or fiddle with launch controls and invalid warranties, all you have to do is floor the throttle and wave goodbye".

In December 2009, The Wall Street Journal editor Joseph White conducted an extended test-drive and determined that "you can have enormous fun within the legal speed limit as you whoosh around unsuspecting Camry drivers, zapping from 40 to 60 miles per hour in two seconds while the startled victims eat your electric dust". White praised the car's environmental efficiency but said consumer demand reflected not the environmental attributes of the car but its performance. "The Tesla turns the frugal environmentalist aesthetic on its head. Sure, it doesn't burn petroleum, and if plugged into a wind turbine or a nuclear plant, it would be a very low-carbon machine. But anyone who buys one will get the most satisfaction from smoking someone's doors off. The Tesla's message is that "green" technology can appeal to the id, not just the superego".[173]

In December 2009, Motor Trend was the first to independently confirm the Roadster Sport's reported 0 to 97 km/h (0 to 60 mph) time of 3.7 seconds. (Motor Trend recorded 0 to 97 km/h (0 to 60 mph) of 3.70 seconds; it recorded a quarter-mile test at 12.6 sec at 165.1 km/h (102.6 mph)). Engineering editor Kim Reynolds called the acceleration "breathtaking" and said the car confirms "Tesla as an actual car company. ...Tesla is the first maker to crack the EV legitimacy barrier in a century".[174]

In November 2009, Automobile Magazine West Coast editor Jason Cammisa spent a week driving a production Tesla Roadster.[175] Cammisa was immediately impressed with the acceleration, saying the car "explodes off the line, pulling like a small jet plane. ... It's like driving a Lamborghini with a big V-12 revved over 6000 rpm at all times, waiting to pounce—without the noise, vibration, or misdemeanor arrest for disturbing the peace". He also took the car to Infineon Raceway in Sonoma, California, and praised the car for its robustness, saying the Roadster:

"wins the Coolest Car I've Ever Driven award. Why? Despite the flat-out sprints, the drag racing, the donuts, the top-speed runs, and dicing through traffic like there's a jet pack strapped to the trunk, Pacific Gas and Electric—which generated power for the Tesla—released into the atmosphere the same amount of carbon dioxide as would a gasoline-powered car getting 99 mpg. And the Roadster didn't break. It didn't smoke, lock up, freeze, or experience flux-capacitor failure. Over the past ten decades, no company has been able to reinvent the car—not General Motors with the EV1, not Toyota with the Prius. And now, a bunch of dudes from Silicon Valley have created an electric car that really works—as both an environmental fix and a speed fix".

In 2009 the Tesla Roadster was one of the Scandinavian Sports Car of the Year participants. In a comparison made by Nordic car magazines Tekniikan Maailma (Finland), Teknikens Värld (Sweden) and Bil Magasinet (Denmark), critics praised the torque of the car and a track car structure, but also highlighted more negative aspects such as a short battery life; they were unable to drive a full track lap in dry track conditions.[176]

In May 2009, Car and Driver technical editor Aaron Robinson wrote a review based on the first extended test-drive of a production Tesla Roadster. Robinson had the car for nearly a week at his home. He complained of "design anomalies, daily annoyances, absurd ergonomics, and ridiculous economics" and stated he never got to see if the car could go 240 miles on a single charge because the torturous seating forced him to stop driving the car. He also complained of Tesla increasing the car prices on those who had already made deposits and charging extra for previously free necessary components.[177]

In February 2009, automotive critic Dan Neil of the Los Angeles Times called the production Tesla Roadster "a superb piece of machinery: stiff, well sorted, highly focused, dead-sexy and eerily quick". Neil said he had the car for 24 hours but "caned it like the Taliban caned Gillette salesmen and it never even blinked".[178]

In February 2009, Road & Track tested another production vehicle and conducted the first independently verified metered testing of the Roadster. Engineering editor Dennis Simanitis said the testing confirmed what he called "extravagant claims", that the Roadster had a 4.0 s 0 to 97 km/h (0 to 60 mph) acceleration and a 320-kilometre (200 mi) range. They said the Roadster felt like "an over-ballasted Lotus Elise", but the weight was well-distributed, so the car remained responsive. "Fit and finish of our Tesla were exemplary", which Road & Track thought fit the target market. Overall, they considered it a "delight" to drive.[179] Testing a pre-production car in early 2008, Road & Track said "The Tesla feels composed and competent at speed with great turn-in and transitioning response", though they recommended against it as a "primary grocery-getter".[180]

In January 2009, automotive critic Warren Brown of The Washington Post called the production Roadster "a head-turner, jaw-dropper. It is sexy as all get-out". He described the feeling behind the wheel as, "Wheeeeeee! Drive a Tesla, even if you have to fly to Tesla's Menlo Park, Calif., headquarters, to get your hands on one for a day. ... If this is the future of the automobile, I want it".[181]

In a review of a Roadster prototype before the cars were in serial production, Motor Trend gave a generally favorable review in March 2008, stating that, it was "undeniably, unbelievably efficient" and would be "profoundly humbling to just about any rumbling Ferrari or Porsche that makes the mistake of pulling up next to a silent, 2.2 L/100 km; 126 mpg‑imp (105 mpg‑US) Tesla Roadster at a stoplight"; they nonetheless detected a "nasty drive-train buck" during the test drive of an early Roadster with the older, two-speed transmission.[182]

In a July 8, 2007, review of a prototype Roadster, Jay Leno wrote, "If you like sports cars and you want to be green, this is the only way to go. The Tesla is a car that you can live with, drive and enjoy as a sports car. I had a brief drive in the car and it was quite impressive. This is an electric car that is fun to drive".[183]

In a November 27, 2006, review of a prototype Roadster in Slate, Paul Boutin wrote, "A week ago, I went for a spin in the fastest, most fun car I've ever ridden in—and that includes the Aston Martin I tried to buy once. I was so excited, in fact, that I decided to take a few days to calm down before writing about it. Well, my waiting period is over, I'm thinking rationally, and I'm still unbelievably stoked about the Tesla".[184]

Top Gear controversy

In the third quarter of 2008, Top Gear's Jeremy Clarkson reviewed two production Roadsters with the v1.5 transmission and described the driving experience with the exclamations "God Almighty! Wave goodbye to the world of dial-up, and say hello to the world of broadband motoring!" and "This car is biblically quick!" when comparing the acceleration versus the car the Roadster was based on, a Lotus Elise. Clarkson also noted, however, that the handling of the car was not as sharp as that of the Elise: "through the corners things are less rosy".[185] The segment also claimed that the car's batteries would run flat after 89 km (55 mi) of heavy use on a track[186] and showed the car being pushed off the track.[187]

Tesla spokesperson responded with statements in blogs and to mainstream news organizations that the cars provided to Top Gear never had less than 20% charge and never experienced brake failure.[188] In addition, neither car provided to Top Gear needed to be pushed off the track at any point.[189] Clarkson also showed a wind turbine with stationary rotor blades and complained that it would take countless hours to refuel the car using such a source of electricity, although the car can be charged from a 240 V 70 A outlet in as little as 3.5 hours.[190][188] After numerous blogs and several large news organizations began following the controversy,[191] the BBC issued a statement saying "the tested Tesla was filmed being pushed into the shed in order to show what would happen if the Roadster had run out of charge. Top Gear stands by the findings in this film and is content that it offers a fair representation of the Tesla's performance on the day it was tested", without addressing the other alleged misrepresentations that Tesla highlighted to the media.[192] After several weeks of increasing pressure and inquiries from the BBC, Clarkson wrote a blog entry for The Times, acknowledging that "Inevitably, the film we had shot was a bit of a mess. There was a handful of shots of a silver car. Some of a grey car". "But as a device for moving you and your things around, it is about as much use as a bag of muddy spinach".[185] In the months that followed Clarkson's acknowledgment, the original episode—including the misstatements—reran on BBC America and elsewhere without any editing.[citation needed]

On March 29, 2011, Tesla sued the programme over libel and malicious falsehood, while simultaneously launching the website TeslaVsTopGear.com. The current position of Tesla is found on its web page.[193] In a blogpost, producer Andy Wilman has referred to Tesla's allegations as a "crusade" and contested the truth value of Tesla's statements.[194] On October 19, 2011, the High Court in London rejected Tesla's libel claim.[195] Tesla appealed High Court's decision to the Court of Appeal, where a three-judge panel of Lords Justice upheld the lower court's decision, and ordered Tesla to pay the BBC's legal costs of £100,000.[196]

Sales

Tesla delivered approximately 2,450 Roadsters worldwide between February 2008 and December 2012.[8][9][10] Featuring new options and enhanced features, the 2012 Tesla Roadster was sold in limited numbers only in mainland Europe, Asia and Australia, and as of July 2012, less than 140 units were available for sale in Europe and Asia before the remaining inventory would be sold out.[9] Tesla's US exemption for not having special two-stage passenger airbags expired for cars made after the end of 2011 so the last Roadsters were not sold in the American market for regulatory reasons.[9][33][34] The U.S. was the leading market with about 1,800 Roadsters sold.[197] There were fewer than 50 right-hand-drive models of the Tesla Roadster produced and hand built in the UK.[citation needed]

United States

The Roadster had a three-year, 58,000 km (36,000 mi) warranty. Tesla also offered an extended powertrain warranty and a battery replacement warranty.[citation needed]

In July 2009, Tesla announced that US consumers could finance the Roadster through Bank of America. Financing was available for up to 75% of the total vehicle purchase price.[198][better source needed]

Tesla sold Roadsters directly to customers. It sold them online, in 13 showrooms and over the phone in North America and Europe. Tesla does not operate through franchise dealerships but operates company-owned stores. The company said that it took its retail cues from Apple, Starbucks and other non-automotive retailers.[199]

Outside the United States

The company has been shipping cars to European customers since mid-2009. Tesla sold out of its EU special-edition vehicle, which had a 2010 model-year production run of 250 cars.[200] A total of 575 units have been sold in Europe through October 2012.[201]

Tesla first overseas showroom opened in London in 2009, with right-hand-drive models promised for early 2010.[12] Showrooms in Munich and Monaco were also added in 2009, followed by Zurich and Copenhagen in 2010 and Milan in 2011.[202][203] Reservations for the 2010 Roadster were available for a €3,000 refundable reservation fee.[204][205]

From 2009 to 2014, Hansjoerg von Gemmingen of Karlsruhe, Germany drove his Tesla Roadster 400,000 km (250,000 mi), this being the mileage world record for an all-electric vehicle[206][207] and reached 520,000 km (320,000 mi) in 2017. He also drove another 200,000 km (120,000 mi) in a Tesla Model S and voiced his plan to become the first man to travel a million kilometres in an electric vehicle.[208]

Kevin Yu, the director of Tesla Motors Asia Pacific, said Roadsters in Japan had additional yearly taxes for exceeding the width limit of normal sized cars.[citation needed]

Pricing complaints

In 2009, Roadster reservation holders who had already placed deposits up to US$50,000 to lock in their orders were informed that their orders had been unlocked and that they had to re-option their ordered vehicles on the threat of losing their spot on the orders list. Tesla then raised the prices of several options, and a new Tesla Roadster with the same set of features that had previously been standard became US$6,700 more expensive than before.[209] For example, the high performance charger that was previously claimed to be standard on all vehicles was changed to be an optional feature costing US$3,000, and the previously claimed standard forged alloy wheels became a US$2,300 upgrade.[210] One person who pre-ordered a Tesla Roadster complained:

"I am [pre-ordered owner] number 395. I am not a rich person dabbling in a plaything. I thought I was actually doing some good by supporting a company that was moving us to a more sustainable future. I put $50,000 of my own money down on this car in May of 2007. I withstood the delays. I held in there when it almost seemed the company was going bankrupt. Now, after locking in my options, they pull this on me."[211]

Awards

The world distance record of 501 km (311 mi) for a production electric car on a single charge was set by a Roadster on October 27, 2009, during the Global Green Challenge in outback Australia, in which it averaged a speed of 40 km/h (25 mph).[212][213] In March 2010, a Tesla Roadster became the first electric vehicle to win the Monte Carlo Alternative Energy Rally and the first to win any Federation Internationale de l'Automobile-sanctioned championship when a Roadster driven by former Formula One driver Érik Comas beat 96 competitors for range, efficiency and performance in the three-day, nearly 1,000-kilometre (620 mi) challenge.[214]

2008 to Tesla co founder chairman and product architect Elon Musk The company produced 500 similar vehicles through June 2009 In July 2009 Tesla began production of its 2010 model year Roadster the first major product upgrade 19 Simultaneously Tesla began producing the Roadster Sport the first derivative of Tesla s proprietary patented powertrain The car accelerates from 0 to 97 km h 0 to 60 mph in 3 7 seconds compared to 3 9 seconds for the standard Roadster Changes for the 2010 model year cars included 20 An upgraded interior and push button gear selector including executive interior of exposed carbon fiber and premium leather and clear coat carbon fiber body accents Locking push button glove box wrapped in leather A centrally mounted video display screen to monitor real time data including estimated range power regenerated and the number of barrels of oil saved This screen is visible to the driver and passenger Adjustable custom tuned suspension The shock absorbers response and anti sway bars are manually adjustable More powerful and immediate heating ventilation and air conditioning More efficient motor and hand wound stator The increase in efficiency allows the motor to deliver higher peak power A suite of sound deadening measures to dramatically reduce noise vibration and harshness For instance engineers added pellets to a member of the chassis side rail These pellets expand by 50 times original volume during the adhesive heating cycle to eliminate rattles All of these features except for the motor were available either as standard or as add on option for the non sport model Beginning mid March 2010 Tesla in an effort to show off the practicality of its electric cars sent one of its Roadsters around the world Starting at the Geneva auto show the Roadster completed its journey upon its arrival in Paris on September 28 2010 21 In July 2010 Tesla introduced the Roadster 2 5 the latest update of the Roadster 22 New features in Roadster 2 5 include A new look which included a new front fascia with diffusing vents and rear diffuser reflecting the future of Tesla design Directional forged wheels available in both silver and black New seats

ever offered though not won on The Price Is Right in a playing of Golden Road on April 22 2010 for Earth Day 23 A Roadster was used as a promotional tool for a wind power electricity company in 2012 24 25 Tesla produced the Roadster until January 2012 when its supply of Lotus gliders ran out as its contract with Lotus Cars for 2 500 gliders expired at the end of 2011 9 26 27 28 Tesla stopped taking orders for the Roadster in the U S market in August 2011 29 30 The next generation will not be based on the Lotus gliders but instead on a shortened version of the architecture developed for the Tesla Model S 31 32 Featuring new options and enhanced components the 2012 Tesla Roadster was sold in limited numbers only in Europe Asia and Australia Tesla s U S exemption for not having special two stage passenger airbags expired for cars made after the end of 2011 so the last Roadsters could not be sold in the American market 33 34 Fifteen Final Edition Roadsters were produced to close the manufacturing cycle of Tesla s first electric car 35 Tesla announced an optional upgrade to current Roadsters the Roadster 3 0 in December 2014 It offered a new battery pack from LG Chem 36 increasing capacity by 50 to 70 kWh a new aero kit designed to reduce drag and new tires with lower rolling resistance 37 38 As of December 2020 the Roadster 3 0 upgrade package has been removed from Tesla s website citation needed Development EditSee also History of Tesla Inc The Roadster was developed by Tesla to mass produce AC Propulsion s tzero concept car After Martin Eberhard sold NuvoMedia to TV Guide he wanted a sports car with high mileage but could not find one His battery experience with the Rocket eBook inspired him to develop an electric car 39 The production idea was conceived by Eberhard and Marc Tarpenning who incorporated Tesla Motors in Delaware on July 1 2003 to pursue the idea commercially 40 South African born entrepreneur Elon Musk took an active role within the company starting in 2004 including investing US 7 5 million overseeing Roadster product design from the beginning and greatly expanding Tesla s long term strategic sales goals by using the sports car to fund the development of mainstream vehicles 41 42 Musk became Tesla s chairman of the board in April 2004 and helped recruit JB Straubel as chief technology officer in March 2004 43 Musk received the Global Green 2006 product design award for the design of the Tesla Roadster presented by Mikhail Gorbachev 44 and he received the 2007 Index Design award for the design of the Tesla Roadster 45 Tesla Roadster France Tzero the proof of concept Tesla Before Tesla had developed the Roadster s proprietary powertrain they borrowed an AC Propulsion Tzero vehicle as a test mule and converted from lead acid AGM batteries to lithium ion cells which substantially increased the range reduced weight and boosted 0 60 mph 0 97 km h performance Tesla then licensed AC Propulsion s EV power system design and reductive charging patent which covers integration of the charging electronics with the inverter thus reducing mass complexity and cost Tesla however was dissatisfied with how the motor and transmission worked in the chassis 46 Tesla then designed and built its own power electronics motor and other drivetrain components that incorporated this licensed technology from AC Propulsion 47 48 49 Given the extensive redevelopment of the vehicle Tesla Motors no longer licenses any proprietary technology from AC Propulsion The Roadster s powertrain is unique 50 External images Tesla Roadster and Lotus Elise Black Roadster and grey EliseOn July 11 2005 Tesla and British sports car maker Lotus entered an agreement about products and services based on the Lotus Elise where Lotus provided advice on designing and developing a vehicle as well as producing partly assembled vehicles 51 and amended in 2009 52 helped with basic chassis development The Roadster has a parts overlap of roughly 6 with the Lotus Elise 53 a 2 inch longer wheelbase and a slightly stiffer chassis according to Eberhard 54 Tesla s designers chose to construct the body panels using resin transfer molded carbon fiber composite to minimize weight this choice makes the Roadster one of the least expensive cars with an entirely carbon fiber skin 53 Several prototypes of the Tesla Roadster were produced from 2004 through 2007 Initial studies were done in two test mule vehicles based on Lotus Elises equipped with all electric drive systems Tesla then built and tested ten engineering prototypes EP1 through EP10 in late 2006 and early 2007 which led to many minor changes Next Tesla produced at least 26 validation prototypes which were delivered beginning in March 2007 55 These final revisions were endurance and crash tested in preparation for series production citation needed In August 2007 Martin Eberhard was replaced by an interim CEO Michael Marks 56 Marks accepted the temporary position while a recruitment was undertaken In December 2007 Ze ev Drori became the CEO and president of Tesla In October 2008 Musk succeeded Drori as CEO Drori became vice chairman and left the company in December In January 2008 the U S National Highway Traffic Safety Administration NHTSA announced that it would grant a waiver of the advanced air bag rule 57 noting that the Tesla Roadster already includes standard air bags similar waivers have been granted to many other small volume manufacturers as well including Lotus Ferrari and Bugatti 58 59 60 Tesla delivered its first production car in February 2008 to Musk Tesla announced in early August 2009 that Roadster sales had resulted in overall corporate profitability for the month of July 2009 earning US 1 million on revenue of US 20 million 61 Tesla which signed a production contract with Group Lotus in 2007 to produce gliders complete cars minus electric powertrain for the Roadster announced in early 2010 that Roadster production would continue until early 2012 Starting one year prior to the end of the contract Tesla put a hiatus on new orders to allow time for tooling changes at Lotus s assembly plant in the UK 62 Several years later in 2018 Musk would go on to say that using the Lotus Elise as a base for the Roadster was a poor strategy This is because the Elise was incompatible with the intended AC Propulsion technology and was modified so extensively only 7 of the original Elise remained in the final production version 63 Production Edit Interior of Roadster 2 5 from July 2010 Tesla s cumulative production of the Roadster reached 1 000 cars in January 2010 64 The Roadster is considered an American car though many carry a Vehicle Identification Number beginning with the letter S which is the designation for the United Kingdom 65 Some however carry a number starting with 5 appropriate to the US Parts were sourced from around the world The body panels came from French supplier Sotira These were sent from France to Hethel U K where Tesla contracted with Lotus to build the Roadster s unique chassis 66 67 The Roadster shares roughly 6 of its components with the Lotus Elise shared components include the windshield airbags some tires some dashboard parts and suspension components The Roadster s single speed gearbox was made in Detroit to Tesla s specifications by Auburn Hills Michigan based supplier BorgWarner Brakes and airbags were made by Siemens in Germany and some crash testing was conducted at Siemens as well 68 30 40 of components were sourced from Taiwan 69 For Roadsters bound for customers in North America the chassis was then sent to Menlo Park California for final assembly and for Roadsters bound for customers in Europe or elsewhere outside of North America the chassis was sent to a facility at Wymondham near Hethel for final assembly At these final assembly locations Tesla employees installed the entire powertrain which consisted of the battery pack power electronics module gearbox and motor Tesla also performed rigorous pre delivery inspection on every car before customers took ownership citation needed Tesla ordered 2 500 gliders from Lotus which ended supplies in December 2011 when their contract expired 27 28 Tesla ended production of the Roadster in January 2012 26 Timeline Edit Subsequent to completion of production car number one at Hethel the company announced problems with transmission reliability The development transmission with first gear enabled to accelerate 0 to 97 km h 0 to 60 mph in 4 seconds was reported to have a life expectancy of as low as only a few thousand miles Tesla s first two transmission suppliers were unable to produce transmissions in quantity that could withstand the gear shift requirements of the high torque high rpm electric motor In December 2007 Tesla announced plans to ship the initial Roadsters with the transmissions locked into second gear to provide 0 to 97 km h 0 to 60 mph acceleration in 5 7 seconds The first production car was not delivered with this interim solution P1 has both transmission gears enabled According to the plan the initial transmissions were to be swapped out under warranty when the finalized transmission power electronics module PEM and cooling system became available The EPA range of the car was also restated downward from 394 to 356 km 245 to 221 mi The downward revision was attributed to an error in equipment calibration at the laboratory that conducted the original test 70 71 72 During the first two months of production Tesla produced a total of three Roadsters P3 VINF002 P4 VINF004 and P5 VINF005 Production car 1 P1 and P2 were built prior to the start of regular series production which began March 17 2008 73 By September 10 2008 Tesla had delivered 27 of the cars to customers It was also reported that a newer better transmission had been developed and that production of the car was hoped to reach 20 per week by December 2008 and 40 per week by March 2009 74 Over the next 20 days however only three more cars had been delivered to customers which brought the total to 30 as of September 30 2008 75 By November 19 2008 more than 70 of the cars had been delivered to customers 76 By December 9 2008 the 100th car had been delivered 77 By February 11 2009 200 Roadsters had been produced 78 By April 2 2009 320 Roadsters had been delivered 79 In May 2009 Tesla issued a safety recall for all 345 of its Roadsters that were manufactured before April 22 2009 Tesla sent technicians to customers homes to tighten the rear inner hub flange bolts Tesla told customers that without this adjustment the driver could lose control of the car and crash The problem originated at the Lotus assembly line that built the Roadster and Lotus also recalled some of its own vehicles Tesla reminded customers that millions of cars are recalled every year 80 81 By the end of May 2009 the 500th Roadster had been delivered 82 Tesla made its first profit ever in July 2009 when it shipped 109 vehicles the most in a single month at that time 83 By September 15 2009 700 Roadsters had been delivered 84 Tesla announced on January 13 2010 that it had produced its 1 000th Roadster The company had delivered vehicles to customers in 43 states and 21 countries worldwide 85 In 2009 Tesla began taking orders from customers in Canada and Canadian deliveries began in February 2010 86 87 In January 2010 Tesla began producing its first right hand drive Roadsters for the UK and Ireland The 2010 model year right hand drive Roadster included a suite of unique noise reduction materials and an upgraded sound system The Roadster started at 86 950 and cost about 1 5p per mile On January 29 2010 in a Form S 1 filing of its preliminary prospectus with the U S Securities and Exchange Commission the company stated that it would halt production of the Roadster in 2011 and replace it with a new model that would not be introduced until 2013 at the earliest we do not plan to sell our current generation Tesla Roadster after 2011 due to planned tooling changes at a supplier for the Tesla Roadster and we do not currently plan to begin selling our next generation Tesla Roadster until at least one year after the launch of the Model S which is not expected to be in production until 2012 88 89 90 The Model S was released in June 2012 91 On March 16 2010 Tesla announced that it had negotiated agreements with key suppliers that will increase total Roadster production by 40 percent and extend sales into 2012 92 also indicating that it would expand into the Asian and Australian markets by 2011 92 On December 2 2010 Tesla had delivered more than 1 400 Roadsters 93 On September 28 2011 Tesla delivered its 100th Roadster in Switzerland 94 Production ended in January 2012 and was no longer available for sale the U S after December 2011 26 More than 2 418 units were sold worldwide through September 2012 The remaining cars were available for sale only in Europe and Asia 9 10 Most of the remaining Roadsters were sold during the fourth quarter of 2012 11 35 95 In 2015 it was announced that a successor to the Roadster would debut in 2019 96 In 2016 Tesla began selling a battery upgrade from 53 kWh to 80 kWh 97 98 99 In 2017 it was announced that a successor to the Roadster would debut in 2020 100 Special final edition Edit Tesla produced a special edition of 15 Final Edition Roadsters to close the production cycle of the electric car The 15 special edition cars were sold in each of the three sales regions North America Europe and Asia and five units were allocated to each The Final Edition Roadster did not have any performance modifications but featured sporting atomic red paint a duo of dark silver stripes on its hood and rear clamshell and exclusive anthracite aluminum wheels 35 Specifications EditMotor Edit Tesla Roadster with hood and trunk open The Roadster is powered by a 3 phase 4 pole induction electric motor with a maximum output power of 185 kW 248 hp 101 Its maximum torque of 200 lb ft 270 N m is immediately available and remains constant from 0 to 6 000 rpm 102 nearly instantaneous torque is a characteristic of electric motors and offers one of the biggest performance differences from internal combustion engines The motor is air cooled and does not need a liquid cooling system 103 104 The Sport model introduced during the Jan 2009 Detroit Auto Show includes a motor with a higher density hand wound stator that produces a maximum of 288 hp 215 kW 105 Both motors are designed for rotational speeds of up to 14 000 rpm and the regular motor delivers a typical efficiency of 88 16 or 90 80 at peak power It weighs less than 70 pounds 32 kg 106 Transmission Edit Starting in September 2008 Tesla selected BorgWarner to manufacture gearboxes and began equipping all Roadsters with a single speed fixed gear gearbox 8 2752 1 with an electrically actuated parking pawl mechanism and a mechanical lubrication pump 15 The company previously worked with several companies including XTrac and Magna International to find the right automatic transmission but a two gear solution proved to be too challenging This led to substantial delays in production At the Town Hall Meeting with owners in December 2007 Tesla announced plans to ship the initial 2008 Roadsters with their interim Magna two speed direct shift manual transmissions locked into second gear limiting the performance of the car to less than what was originally stated 0 to 97 km h 0 to 60 mph in 5 7 seconds instead of the announced 4 0 seconds Tesla also announced it would upgrade those transmissions under warranty when the final transmission became available 70 72 107 At the Town Hall Meeting with owners on January 30 2008 Tesla Motors described the planned transmission upgrade as a single speed gearbox with a drive ratio of 8 27 1 combined with improved electronics and motor cooling that retain the acceleration from 0 to 60 mph 0 to 97 km h in under 4 seconds and an improved motor limit of 14 000 rpm to retain the 201 km h 125 mph top speed 108 The upgraded system also improved the maximum torque from 270 to 380 N m 200 to 280 lb ft and improves the Roadster s quarter mile times citation needed Gear selector Edit In the interior the gear selector is similar to a push button automatic with buttons labeled P R N and D while some earlier models have a gear lever similar to that in cars with manual transmission citation needed Performance Edit The Roadster s 0 to 97 km h 0 to 60 mph acceleration time is 3 9 seconds for the Standard model and 3 7 seconds for the 2010 V2 5 Sport which Motor Trend confirmed in the first independent instrumented testing of the V2 5 Sport model The magazine also recorded a 0 to 1 4 mile 0 00 to 0 40 km time of 12 6 seconds at 165 1 km h 102 6 mph 109 Tesla said the top speed is electronically limited to 201 km h 125 mph Tesla claims it has a weight of 1 305 kg 2 877 lb a drag coefficient of Cd 0 35 0 36 110 and a rolling resistance of Crr 0 011 38 Tesla began delivering the higher performance version of the Roadster in July 2009 The Roadster Sport has adjustable dampers and a new hand wound motor capable of 0 to 97 km h 0 to 60 mph in 3 7 seconds 111 Scotty Pollacheck a high performance driver for Killacycle drove a 2010 Tesla Roadster Sport at the Wayland Invitational Drag Race in Portland Oregon in July 2009 He did a quarter mile 400 m in dry conditions in 12 643 seconds setting a new record in the National Electric Drag Racing Association among the SP A3 class of vehicles 112 The EPA combined range specifying distance traveled between charges measured in February 2008 for early production Roadsters was 372 km 231 mi city 360 km 224 mi highway and 365 km 227 mi combined city highway 113 In August 2008 additional testing with the newer Powertrain 1 5 resulted in an EPA combined range of 393 km 244 mi 15 The vehicle set a new distance record when it completed the 388 kilometre 241 mi Rallye Monte Carlo d Energies Alternatives with 58 km 36 mi left on the charge 114 A Roadster drove around the world although flying as cargo over oceans in 2012 115 and repeated it in 80 days with other electric cars in 2016 116 Simon Hackett and Emilis Prelgauskas broke the distance record for an electric vehicle driving 501 km 311 mi from Alice Springs to Marla South Australia in Simon s Tesla Roadster The car had about 4 8 km 3 0 mi of range left when the drive was completed 117 Battery system Edit An electrical plug of the Tesla Roadster Sport The rear side of a Tesla Roadster battery pack The charging screen of a Tesla Roadster Sport Tesla refers to the Roadster s battery pack as the Energy Storage System or ESS The 450 kg 992 lb ESS contains 6 831 lithium ion cells arranged into 11 sheets connected in series each sheet contains 9 bricks connected in series each brick contains 69 cells connected in parallel 11S 9S 69P The cells are of the 18650 form factor commonly found in laptop batteries Sources disagree 118 on the exact type of Li Ion cells GreenCar says lithium cobalt oxide LiCo while researchers at DTU INESC Porto state lithium manganese oxide LMO 119 LiCo has higher reaction energy during thermal runaway than LMO 120 The pack is designed to prevent catastrophic cell failures from propagating to adjacent cells thermal runaway even when the cooling system is off 121 Coolant is pumped continuously through the ESS both when the car is running and when the car is turned off if the pack retains more than a 90 charge The coolant pump draws 146 watts 122 123 124 The cooling and battery management system keeps the temperatures and voltages within specific limits 125 Charging unit A full recharge to 53 kWh requires about 3 hours using the High Power Connector which supplies 70 amp 240 volt electricity 126 127 Tesla said in February 2009 that the ESS had expected life span of seven years 160 000 km 100 000 mi and began selling pre purchase battery replacements for about one third of the battery s price today with the replacement to be delivered after seven years Tesla says the ESS retains 70 capacity after five years and 80 000 km 50 000 mi of driving assuming 16 000 km 10 000 mi driven each year A July 2013 study found that after 160 000 km 100 000 mi Roadster batteries still had 80 85 capacity and the only significant factor is mileage not temperature 128 Tesla announced plans to sell the battery system to TH NK and possibly others through its Tesla Energy Group division The TH NK plans were put on hold by interim CEO Michael Marks in September 2007 129 130 131 TH NK now obtains its lithium ion batteries from Enerdel citation needed Recharging Edit The Roadster uses a proprietary charging connector although Tesla sells a mobile adapter that enables recharging with an SAE J1772 2009 connector 6 The vehicle can be recharged using 132 A wall mounted 208 240 V 70 A maximum current Home Connector This appears to be an OEM version of the TS 70 charging station from ClipperCreek 133 A portable 120 240 V 40 A maximum current Universal Mobile Connector cable that can plug into a NEMA 14 50 receptacle and other 240 V receptacles using adapters A portable 120 V 15 A maximum current Spare Mobile Connector cable that plugs into a standard North American domestic socket Charging times vary depending on the ESS s state of charge the available voltage and the available circuit breaker amp rating current In a best case scenario using a 240 V charger on a 90 A circuit breaker Tesla documents a recharging rate of 90 km 56 mi of range for each hour charging a complete recharge from empty would require just under four hours The slowest charging rate using a 120 V outlet on a 15 A circuit breaker would add 8 0 km 5 mi of range for each hour charging a complete recharge from empty would require 48 hours 134 Technical data Edit Tesla Roadster 135 Tesla Roadster P1 136 1 5 Standard Tesla Roadster 2 0 137 Tesla

2006 Tesla reported the Roadster s battery to wheel efficiency as 110 Wh km 17 7 kWh 100 mi on an unspecified driving cycle either a constant 97 km h 60 mph or SAE J1634 test and stated a charging efficiency of 86 for an overall plug to wheel efficiency of 128 Wh km 20 5 kWh 100 mi 49 139 140 Evolution of the Roadster s plug to wheel efficiency smaller values indicate better efficiency In March 2007 Tesla reported the Roadster s efficiency on the EPA highway cycle as 135 mpg U S equivalent per the conversion rate used by the EPA or 133 Wh km 21 5 kWh 100 mi battery to wheel and 155 Wh km 24 9 kWh 100 mi plug to wheel 141 142 143 144 The official U S window sticker of the 2009 Tesla Roadster showed an EPA rated energy consumption of 32 kWh 100 mi in city and 33 kWh 100 mi on the highway equivalent to 105 mpg city and 102 mpg highway 145 146 The EPA rating for on board energy efficiency for electric vehicles before 2010 was expressed as kilowatt hour per 100 miles kWh 100 mi 147 148 Since November 2010 with the introduction of the Nissan Leaf and the Chevrolet Volt EPA began using a new metric miles per gallon gasoline equivalent MPGe The Roadster was never officially rated by the EPA in MPGe 149 150 In August 2007 Tesla dynamometer testing of a validation prototype on the EPA combined cycle yielded a range of 356 km 221 mi using 149 Wh km 23 9 kWh 100 mi battery to wheel and 209 Wh km 33 6 kWh 100 mi plug to wheel 70 151 In February 2008 Tesla reported improved plug to wheel efficiency after testing a validation prototype car at an EPA certified location Those tests yielded a range of 350 km 220 mi and a plug to wheel efficiency of 199 Wh km 32 1 kWh 100 mi 152 153 In August 2008 Tesla reported on testing with the new single speed gearbox and upgraded electronics of powertrain 1 5 which yielded an EPA range of 393 km 244 mi and an EPA combined cycle plug to wheel efficiency of 174 Wh km 28 kWh 100 mi 154 Roadster being tested through a driving cycle at Argonne National Laboratory s two wheel dynamometer These tests helped researchers develop test procedures to evaluate fuel efficiency in electric vehicles in 2010 In 2007 the Roadster s battery to wheel motor efficiency was reported as 88 16 to 90 on average and 80 at peak power 155 For comparison internal combustion engines have a tank to wheel efficiency of about 15 156 Taking a more complete picture including the cost of energy drawn from its source Tesla reports that their technology assuming electricity generated from natural gas burning power plants has a high well to wheel efficiency of 1 14 km per megajoule compared to 0 202 km MJ for gasoline powered sports cars 0 478 km MJ for gasoline powered commuter cars 0 556 km MJ for hybrid cars and 0 348 km MJ for hydrogen fuel cell

Tesla s website recommends the owner bring the vehicle in for service once a year or every 12 000 miles 163 For other concerns with vehicles Tesla created a mobile service unit that dispatches company trained technicians to customers homes or offices in case the owner is experiencing problems Tesla charges the customer according to the distance the service unit needs to travel one US dollar per mile roundtrip with a 100 dollar minimum 163 Technicians drive company vans equipped with numerous tools and testing equipment to do in the field repairs enhancements and software upgrades Tesla debuted this house call approach in the spring of 2009 when the company announced a recall due to a manufacturing problem in the Lotus assembly plant which also affected the Lotus Elise and other models from the British sports car maker 164 The first Tesla service center in Los Angeles California was opened on Santa Monica Boulevard on May 1 2008 165 Tesla publicly opened their second showroom and service area in Menlo Park California on July 22 2008 The Menlo Park location is also the final assembly area for Tesla Roadsters Tesla also operates service centers in New York City Miami Chicago and Seattle citation needed In 2007 Tesla announced plans to build additional service centers over the following few years to support sales of its next vehicle the Model S sports sedan This included an additional 15 service centers in United States major metropolitan locations 166 Possible locations for sales and service locations in Europe were announced in a letter to customers in May 2008 167 Recalls Edit As of May 2017 update Tesla has issued two product safety recalls for the Roadster 168 In May 2009 Tesla issued a recall for 345 Roadsters manufactured before April 22 2009 Tesla sent technicians to customers homes to tighten the rear inner hub flange bolts Using wording from the National Highway Traffic and Safety Administration Tesla told customers that without this adjustment the driver could lose control of the car 169 The problem originated at the Lotus assembly line where the Roadster glider was built Lotus also recalled some Elise and Exige vehicles for the same reason 170 On October 1 2010 Tesla issued a second product safety recall in the US affecting 439 Roadsters The recall involved the 12V low voltage auxiliary cable from a redundant back up system The recall followed an incident where the low voltage auxiliary cable in a vehicle chafed against the edge of a carbon fiber panel causing a short smoke and a possible fire behind the right front headlamp This issue was limited to the 12V low voltage auxiliary cable and did not involve the main battery pack or main power system 171 Reviews EditTesla Roadster reviews can be grouped in two main categories older reviews of validation prototypes 2006 2008 before Tesla began serial production and customer deliveries and reviews on cars in serial production 2008 2010 citation needed The global online auto review site Autoguide com tested Tesla s fourth generation car in October 2010 Autoguide editor Derek Kreindler said The Tesla Roadster 2 5 S is a massively impressive vehicle more spacecraft than sports car Theories like global warming peak oil and rising oil prices should no longer bring heart palpitations to car fans The Tesla shows just how good zero emissions green technology can be Quite frankly getting into a normal car at the end of the test drive was a major letdown The whirr of the engine the shove in the backside and the little roadster that seems to pivot around you is replaced by a grunting belching feedback free driving experience He continues on that but for a 100 000 car it could use some work complaining of purposefully cheap work 172 In the March 2010 print edition of British enthusiast magazine EVO p 120 editor Richard Meaden was the first to review the all new right hand drive version of the Roadster He said the car had serious instantaneous muscle With so much torque from literally no revs the acceleration punch is wholly alien Away from traffic lights you d murder anything be it a 911 Turbo GT R or 599 simply because while they have to mess about with balancing revs and clutch or fiddle with launch controls and invalid warranties all you have to do is floor the throttle and wave goodbye In December 2009 The Wall Street Journal editor Joseph White conducted an extended test drive and determined that you can have enormous fun within the legal speed limit as you whoosh around unsuspecting Camry drivers zapping from 40 to 60 miles per hour in two seconds while the startled victims eat your electric dust White praised the car s environmental efficiency but said consumer demand reflected not the environmental attributes of the car but its performance The Tesla turns the frugal environmentalist aesthetic on its head Sure it doesn t burn petroleum and if plugged into a wind turbine or a nuclear plant it would be a very low carbon machine But anyone who buys one will get the most satisfaction from smoking someone s doors off The Tesla s message is that green technology can appeal to the id not just the superego 173 In December 2009 Motor Trend was the first to independently confirm the Roadster Sport s reported 0 to 97 km h 0 to 60 mph time of 3 7 seconds Motor Trend recorded 0 to 97 km h 0 to 60 mph of 3 70 seconds it recorded a quarter mile test at 12 6 sec at 165 1 km h 102 6 mph Engineering editor Kim Reynolds called the acceleration breathtaking and said the car confirms Tesla as an actual car company Tesla is the first maker to crack the EV legitimacy barrier in a century 174 In November 2009 Automobile Magazine West Coast editor Jason Cammisa spent a week driving a production Tesla Roadster 175 Cammisa was immediately impressed with the acceleration saying the car explodes off the line pulling like a small jet plane It s like driving a Lamborghini with a big V 12 revved over 6000 rpm at all times waiting to pounce without the noise vibration or misdemeanor arrest for disturbing the peace He also took the car to Infineon Raceway in Sonoma California and praised the car for its robustness saying the Roadster wins the Coolest Car I ve Ever Driven award Why Despite the flat out sprints the drag racing the donuts the top speed runs and dicing through traffic like there s a jet pack strapped to the trunk Pacific Gas and Electric which generated power for the Tesla released into the atmosphere the same amount of carbon dioxide as would a gasoline powered car getting 99 mpg And the Roadster didn t break It didn t smoke lock up freeze or experience flux capacitor failure Over the past ten decades no company has been able to reinvent the car not General Motors with the EV1 not Toyota with the Prius And now a bunch of dudes from Silicon Valley have created an electric car that really works as both an environmental fix and a speed fix In 2009 the Tesla Roadster was one of the Scandinavian Sports Car of the Year participants In a comparison made by Nordic car magazines Tekniikan Maailma Finland Teknikens Varld Sweden and Bil Magasinet Denmark critics praised the torque of the car and a track car structure but also highlighted more negative aspects such as a short battery life they were unable to drive a full track lap in dry track conditions 176 In May 2009 Car and Driver technical editor Aaron Robinson wrote a review based on the first extended test drive of a production Tesla Roadster Robinson had the car for nearly a week at his home He complained of design anomalies daily annoyances absurd ergonomics and ridiculous economics and stated he never got to see if the car could go 240 miles on a single charge because the torturous seating forced him to stop driving the car He also complained of Tesla increasing the car prices on those who had already made deposits and charging extra for previously free necessary components 177 In February 2009 automotive critic Dan Neil of the Los Angeles Times called the production Tesla Roadster a superb piece of machinery stiff well sorted highly focused dead sexy and eerily quick Neil said he had the car for 24 hours but caned it like the Taliban caned Gillette salesmen and it never even blinked 178 In February 2009 Road amp Track tested another production vehicle and conducted the first independently verified metered testing of the Roadster Engineering editor Dennis Simanitis said the testing confirmed what he called extravagant claims that the Roadster had a 4 0 s 0 to 97 km h 0 to 60 mph acceleration and a 320 kilometre 200 mi range They said the Roadster felt like an over ballasted Lotus Elise but the weight was well distributed so the car remained responsive Fit and finish of our Tesla were exemplary which Road amp Track thought fit the target market Overall they considered it a delight to drive 179 Testing a pre production car in early 2008 Road amp Track said The Tesla feels composed and competent at speed with great turn in and transitioning response though they recommended against it as a primary grocery getter 180 In January 2009 automotive critic Warren Brown of The Washington Post called the production Roadster a head turner jaw dropper It is sexy as all get out He described the feeling behind the wheel as Wheeeeeee Drive a Tesla even if you have to fly to Tesla s Menlo Park Calif headquarters to get your hands on one for a day If this is the future of the automobile I want it 181 In a review of a Roadster prototype before the cars were in serial production Motor Trend gave a generally favorable review in March 2008 stating that it was undeniably unbelievably efficient and would be profoundly humbling to just about any rumbling Ferrari or Porsche that makes the mistake of pulling up next to a silent 2 2 L 100 km 126 mpg imp 105 mpg US Tesla Roadster at a stoplight they nonetheless detected a nasty drive train buck during the test drive of an early Roadster with the older two speed transmission 182 In a July 8 2007 review of a prototype Roadster Jay Leno wrote If you like sports cars and you want to be green this is the only way to go The Tesla is a car that you can live with drive and enjoy as a sports car I had a brief drive in the car and it was quite impressive This is an electric car that is fun to drive 183 In a November 27 2006 review of a prototype Roadster in Slate Paul Boutin wrote A week ago I went for a spin in the fastest most fun car I ve ever ridden in and that includes the Aston Martin I tried to buy once I was so excited in fact that I decided to take a few days to calm down before writing about it Well my waiting period is over I m thinking rationally and I m still unbelievably stoked about the Tesla 184 Top Gear controversy Edit In the third quarter of 2008 Top Gear s Jeremy Clarkson reviewed two production Roadsters with the v1 5 transmission and described the driving experience with the exclamations God Almighty Wave goodbye to the world of dial up and say hello to the world of broadband motoring and This car is biblically quick when comparing the acceleration versus the car the Roadster was based on a Lotus Elise Clarkson also noted however that the handling of the car was not as sharp as that of the Elise through the corners things are less rosy 185 The segment also claimed that the car s batteries would run flat after 89 km 55 mi of heavy use on a track 186 and showed the car being pushed off the track 187 Tesla spokesperson responded with statements in blogs and to mainstream news organizations that the cars provided to Top Gear never had less than 20 charge and never experienced brake failure 188 In addition neither car provided to Top Gear needed to be pushed off the track at any point 189 Clarkson also showed a wind turbine with stationary rotor blades and complained that it would take countless hours to refuel the car using such a source of electricity although the car can be charged from a 240 V 70 A outlet in as little as 3 5 hours 190 188 After numerous blogs and several large news organizations began following the controversy 191 the BBC issued a statement saying the tested Tesla was filmed being pushed into the shed in order to show what would happen if the Roadster had run out of charge Top Gear stands by the findings in this film and is content that it offers a fair representation of the Tesla s performance on the day it was tested without addressing the other alleged misrepresentations that Tesla highlighted to the media 192 After several weeks of increasing pressure and inquiries from the BBC Clarkson wrote a blog entry for The Times acknowledging that Inevitably the film we had shot was a bit of a mess There was a handful of shots of a silver car Some of a grey car But as a device for moving you and your things around it is about as much use as a bag of muddy spinach 185 In the months that followed Clarkson s acknowledgment the original episode including the misstatements reran on BBC America and elsewhere without any editing citation needed On March 29 2011 Tesla sued the programme over libel and malicious falsehood while simultaneously launching the website TeslaVsTopGear com The current position of Tesla is found on its web page 193 In a blogpost producer Andy Wilman has referred to Tesla s allegations as a crusade and contested the truth value of Tesla s statements 194 On October 19 2011 the High Court in London rejected Tesla s libel claim 195 Tesla appealed High Court s decision to the Court of Appeal where a three judge panel of Lords Justice upheld the lower court s decision and ordered Tesla to pay the BBC s legal costs of 100 000 196 Sales EditTesla delivered approximately 2 450 Roadsters worldwide between February 2008 and December 2012 8 9 10 Featuring new options and enhanced features the 2012 Tesla Roadster was sold in limited numbers only in mainland Europe Asia and Australia and as of July 2012 less than 140 units were available for sale in Europe and Asia before the remaining inventory would be sold out 9 Tesla s US exemption for not having special two stage passenger airbags expired for cars made after the end of 2011 so the last Roadsters were not sold in the American market for regulatory reasons 9 33 34 The U S was the leading market with about 1 800 Roadsters sold 197 There were fewer than 50 right hand drive models of the Tesla Roadster produced and hand built in the UK citation needed Roadster with California s Clean Air Vehicle stickers at the extremes of the bumper that allows access to HOV lanes with solo driver United States Edit The Roadster had a three year 58 000 km 36 000 mi warranty Tesla also offered an extended powertrain warranty and a battery replacement warranty citation needed In July 2009 Tesla announced that US consumers could finance the Roadster through Bank of America Financing was available for up to 75 of the total vehicle purchase price 198 better source needed Tesla sold Roadsters directly to customers It sold them online in 13 showrooms and over the phone in North America and Europe Tesla does not operate through
