Chevrolet Kodiak

The Chevrolet Kodiak and GMC TopKick are a range of medium-duty trucks that were produced by the Chevrolet and GMC divisions of General Motors from 1980 to 2009. Introduced as a variant of the medium-duty C/K truck line, three generations were produced. Slotted between the C/K trucks and the GMC Brigadier Class 8 conventional, the Kodiak/TopKick were developed as a basis for vocationally oriented trucks, including cargo haulers, dump trucks, and similar vehicles; on later generations, both cutaway and cowled-chassis variants were produced for bus use.

Following years of declining market share, General Motors (in line with Ford Motor Company) sought to exit heavy-truck manufacturing. After struggling to enter joint ventures or sell the rights to its product line, the company ended production of the Kodiak and TopKick in 2009. The final medium-duty truck, a GMC TopKick 5500, rolled out of Flint Truck Assembly on July 31, 2009.[2]

For the 2019 model year, after a ten-year hiatus, General Motors re-entered the conventional medium-duty truck segment. Developed in a joint venture with Navistar International, the Chevrolet Silverado 4500/5500 is a Class 4-6 vehicle.[3] Slightly smaller than the Kodiak/Topkick, the Silverado 4500/5500 is marketed exclusively as a Chevrolet (with no GMC counterpart).

1980-1989 GMC TopKick C7000

For 1981, General Motors introduced the Chevrolet Kodiak and GMC TopKick as a variant of the medium-duty C/K trucks.[5] A Class 7 truck, the Kodiak was developed to use the Caterpillar 3208 V8 diesel (sourced from the larger Chevrolet Bruin/GMC Brigadier). To accommodate the larger engine (which used a larger radiator), the cab was mounted several inches higher, allowing for a higher hoodline (repositioning the headlamps between the grille and bumper); the hood length was shortened, reducing the BBC length from 98 to 92 inches.[4] In line with the Bruin/Brigadier, the Kodiak was offered with both single and tandem-axle drive configurations; both straight truck and semitractor configurations were produced.[4]

Officially designated as the Chevrolet C70 (or GMC C7000), the Kodiak name followed the Chevrolet "frontier beast" naming tradition for its heavy conventionals (Chevrolet Bison and Chevrolet Bruin) while the GMC TopKick was a military slang term (following GMC Brigadier and GMC General). Following the retirement of Chevrolet from the Class 8 truck segment after 1981, the Class 7 Kodiak became the largest truck offered by Chevrolet, while the TopKick remained slotted below the Brigadier. .

GMC TopKick with raised-roof cab

For 1990, the second generation of the Kodiak/TopKick were introduced, shifting to the GMT530 architecture. The new chassis consolidated all GM medium-duty trucks under the Kodiak/TopKick model family, with the upper end of the C/K series limited to "1-ton" trucks. Following the exit of GM from the Class 8 truck segment (and the discontinuation of the GMC General, Astro, and Brigadier), the model line was now the largest vehicle produced by the company.

In line with the previous generation, while designed with its own heavier-duty chassis, the cab of GMT530 trucks was derived from the GMT400 C/K pickup (introduced in 1988) to lower the costs of tooling. As before, two-door and four-door configurations were offered. Initially, Kodiak models were available in base and Silverado trim and TopKick models were available in SL and SLE trim, but all trim levels were phased out for 1994.

Over its thirteen-year production run, the GMT530 platform underwent relatively few changes; as airbags were not required in medium-duty trucks, the 1988-design interior was retained through the entire production run. In 1991, a raised-roof cab became optional (a feature distinct to GMT530 trucks). For 1997, a lower-profile "aerodynamic" hood became available (not offered on C8500 models, severe-service, or school bus applications). Models equipped with this hood featured C5500-C8500 badging rather than Kodiak/TopKick badging, a change which extended to standard hood models for 1998, effectively bringing the medium-duty trucks in line with the rest of the C/K naming convention.

In a break from the single engine offering of the first generation Kodiak/TopKick, the GMT530 series offered multiple engine options. Gasoline engines were offered as standard equipment, with diesel engines now offered as an option. Carried over from the previous generation medium-duty C/K trucks, the standard gasoline engine was a 6.0L V8 (now fitted with fuel injection) with an optional carbureted 7.0L V8 (replaced by a 7.4L V8 in 1991).[6] During the mid-1990s, the 6.0L engine was dropped, making the 7.4L V8 the standard engine; in 2002, the engine was replaced by a larger 8.1L Vortec V8 (the largest-displacement V8 ever offered in a mass-produced Chevrolet). Replacing the Caterpillar 3208 V8, the GMT530 offered a 165hp Caterpillar 3116 inline-6 (170hp from 1991[6]). As an optional engine, a Caterpillar 3126 inline-6 was introduced in 1997.

The GMT530 was produced through the 2002 model for North America, with assembly for export markets continuing in Toluca, Mexico through 2008. From 1995 to 2001, GMT530 was assembled in Brazil for Latin America, using components imported from Mexico; all Brazil-market vehicles were produced with Caterpillar 3116 engines. Brazil-market vehicles were badges according to their GMVR (in metric tons) and rounded horsepower output (12-170 for 12 tons-170 hp, 14-190 for 14 tons-190 hp, and 16-220 for 16 tons-220 hp).

In May 2021, the final GMT530-based vehicle built at the Janesville plant was put up for auction. The 2002 GMC C8500 tandem-axle dump truck was owned and operated by the city of Janesville for nearly 20 years prior to the sale. The vehicle bore the signatures of numerous former employees of the plant.[7]

Chevrolet Kodiak C4500 with optional Deluxe Front Appearance Package

For 2003, General Motors released the third-generation Chevrolet Kodiak/GMC TopKick under the GMT560 architecture. As General Motors felt the two names had better marketplace recognition, the medium-duty truck line was released under the previous Kodiak/TopKick nameplates, with Cx500 as a secondary part of the nomenclature. Showcased as part of the redesign was a change in the design layout of the Kodiak/TopKick. To better compete with the better-selling International DuraStar and Freightliner Business Class M2 medium-duty truck ranges, the GMT560 trucks switched to a vertically oriented cab configuration to allow for a lower cab floor, increased cab space, and better entry and exit. Derived from the Chevrolet Express/GMC Savana full-size van, the cab was produced in two-door and four-door configurations (as the commercial trucks had a Gross Vehicle Weight Rating (GVWR) of over 8500 pounds, they were not equipped with airbags).

During its production, the GMT560 was produced with few changes. C4500 and C5500 models utilized a separate hood design from the C6500 and heavier-duty models. A "Deluxe Front Appearance Package" was available on all models, featuring a chrome-trimmed mesh grille, a chrome bumper, and, on C4500 and C5500 models, chrome-trimmed quad headlights. The mesh grille without chrome was available as a separate option as well. Carried over from the previous generation, the GMT560 chassis was produced in Class 5-7 configurations, in C4500, C5500, C6500, and C7500 models. Effectively, a successor to the GMC Brigadier, a tandem-axle C8500 model was introduced (with up to a 46,000-lb GVWR).

On the GMT560 Kodiak/TopKick, the powertrain configuration was derived from the model specification. On C4500/C5500s, an 8.1-liter V8 was carried over from the previous generation, with a 6.6-liter Duramax V8 diesel replacing the Caterpillar 3116. Diesel engines were standard on C6500s and up, with Isuzu's 7.8-liter Duramax LG4 inline-six as standard, with a 7.2-liter Caterpillar C7 (a redesigned Caterpillar 3126) offered as an option.

GMT560 four-wheel drive edit

In 2005, GM added four-wheel drive as a factory-installed option on C4500/C5500 Kodiak/TopKicks. In a break from GM truck naming tradition, the models did not adopt the "K" nomenclature, becoming the C4500/5500 4x4 model line. In place of independent front suspension (used on the 3500-series pickup trucks), the GMT560 4x4s used a solid front axle suspension. Powered by a 6.6L Duramax V8, the 4x4 used a 5-speed Allison 2000 series in 2005-2006 (replaced by a 6-speed Allison 2350 automatic) with a New Process 273C transfer case. 5.13:1 was the only axle gear ratio offered for 4x4 versions.

For 2007, GM introduced a heavier-duty 9000 lb spring and brake option package for the Dana 70HD front axle; rear axles (Dana S14-110L) were available in four sizes: 11,000 lb, 13,500 lb, 15,000 lb, and 19,000 lb (the latter two were options on two-wheel drive configurations).

Isuzu H-Series edit

For 2003, Isuzu released a conventional-cab truck, named the Isuzu H-Series. Intended largely for vocational use, the Isuzu H-Series was marketed as a competitor for the Hino 600 and Freightliner M2. Based on the Kodiak/TopKick C6500/C7500, the H-Series differed solely in its grille design, sharing the 7.8L Duramax inline-six with the C6500/7500 and the Chevrolet/GMC T6500/7500 (based on the Isuzu Forward).

As of current production, the H-Series is the first (and only) conventional-cab truck sold by Isuzu.

Discontinuation and replacement edit

In December 2007, GM announced its intention to sell its medium-duty truck business, including the Kodiak and TopKick, to Navistar International.[8] In August 2008, both GM and Navistar announced that their memorandum of understanding for the purchase had expired and was not renewed.[9][10]

After four years of working with multiple potential buyers, including an anticipated five-year deal with Isuzu Motors announced late in January 2009 to take over the production line in Flint, Michigan,[11] General Motors decided to wind down its medium-duty truck operations.[2] Production of the Chevy Kodiak and GMC TopKick medium duty trucks in Flint ceased on July 31, 2009.

Chevrolet Silverado HD (2019-present) edit

 
2019 Chevrolet Silverado 5500HD crew cab

At the 2018 Work Truck Show in Indianapolis, Indiana, General Motors launched a new line of medium-duty trucks for the 2019 model year. Developed in a joint venture with Navistar International,[3] Chevrolet launched the Chevrolet Silverado 4500HD, 5500HD, and 6500HD (for Classes 4,5, and 6, respectively[3][12]). In the joint venture, the trucks are assembled by Navistar in its Springfield, Ohio facility; Navistar also markets the model line as the International CV.[13]

In a shift from previous generations of GM commercial trucks, the Silverado 4500HD/5500HD/6500HD is sold with no GMC counterpart. Alongside with its dual branding by Navistar, General Motors is changing the market position of GMC, shifting it away from commercial fleet sales and focusing towards its premium Denali model lines.[14] In another break from tradition, the Kodiak name was retired, as the Silverado name was expanded to nearly the entire Chevrolet truck range, with the exception of the Colorado mid-size pickup, the Express van, and the Low Cab Forward (Isuzu Elf/NPR).

Sharing its cab with the K2XX-generation Silverado, the medium-duty Silverado was designed with a dedicated chassis with a forward-tilting hood; both 4x2 and 4x4 configurations are produced. As of current production, the model line is offered with a 350 hp 6.6L Duramax turbodiesel V8; the engine is paired with a choice of Allison automatic transmissions, depending upon the truck's intended usage.[3][12][15]

Variants edit

School bus edit

 
Blue Bird/GMC school bus

Following in the tradition of its medium-duty C/K predecessor, the second-generation Kodiak/TopKick was utilized by General Motors to supply the school bus industry throughout its production run. In an unusual move at the time, starting in 1992, GM offered the Kodiak/TopKick solely to a single body manufacturer, Blue Bird Corporation from 1992 to 2002. While the GM chassis was not offered to other manufacturers, Blue Bird offered other available combinations (Ford B700, International 3800, and the later Freightliner FS65) for an additional price. The pairing of manufacturer and chassis supplier would become common through the 1990s in school bus manufacturing, but after 2002, General Motors would become unable to remain a chassis supplier. The Kodiak/TopKick school bus chassis is also notable for being one of the last full-size school bus chassis powered by a gasoline engine.

Pickup conversion edit

A special Kodiak C4500 was introduced at the 2006 Chicago Auto Show. Aimed at the International RXT (also introduced there), pricing was set at $70,000. The two shared a number of similarities, such as the options included in their premium packages (a powerful audio system and DVD-based navigation system). In comparison, the C4500 had higher power (300 hp versus 230 hp) while the RXT had a higher towing capacity at 16,000 lb (7,300 kg); the C4500 was a 4x4 like the larger International CXT.

A conversion of the commercial GMC TopKick called the Ultimate Class IV TopKick Pickup crew cab pickup truck was developed by General Motors and Monroe Truck Equipment (MTE). This special version featured an 8.5-foot (2.6 m) steel dually pickup box and tailgate with custom composite side panels and protective Rhino interior lining. This vehicle served as the alternate mode for the character Ironhide in the first three Transformers films.

Cadillac One edit

Since 2009, the United States Presidential State Car has become labeled "Cadillac One" (in line with Air Force One and Marine One). As a result of its massive size – though officially classified, it is estimated to weigh between 15,000 and 20,000 pounds (6,800 and 9,100 kg)[16] – it is also nicknamed "The Beast".[17][18] Corresponding to its operation by the Secret Service, many details about the vehicle are classified. While its chassis specifications were never officially revealed by Cadillac or the Secret Service,[17] during its development, the vehicle was seen in testing alongside GMT560 GMC TopKicks.[19]

In place of previous limousines, the highly armored vehicle was not based upon a production Cadillac model line, instead wearing a body developed specifically for its use as a state car; externally, the vehicle used various components from several Cadillac model lines.[17]

In 2018, the second generation of "Cadillac One" limousines entered service, again using the medium-duty GMT560 diesel truck chassis.[18] Differing from its predecessor primarily by its adoption of contemporary Cadillac design elements, it is again not derived from a specific model line.[16]
