A field of Group 7 cars participating in a Can-Am race in 1973
The FIA’s new Appendix J regulations for 1966 listed a category for "Group 9 two-seater racing cars" in its draft versions, but this was amended to "Group 7 two-seater racing cars" by the time of publication of the 1966 FIA Yearbook.[1] The new Group 7 regulations specified that cars must be fitted with fenders, windshield, two seats, two doors, headlights, taillights, rollbar, a dual braking system and a self-starter and that they must utilize commercial gasoline.[1]
Group 7 cars were defined as "two-seater competition vehicles built exclusively for speed races on closed circuit".[2] There was no minimum production requirement necessary to earn homologation. As such, the regulations allowed manufacturers and teams freedom to create unique racing cars with no limitations on engines, tires, aerodynamics, or dimensions, as long as the car had room for two seats and was enclosed in bodywork. Races for Group 7 cars were generally short sprints, with few accommodations made for driver comfort.
The formula was current through to 1975,[3] with two-seater racing cars defined under Group 6 regulations from 1976.[4]
Group 7 international formula racing cars (1976 to 1981)
From 1976 the FIA used the Group 7 designation for international formula racing cars.[4] The new Group 7 encompassed International Formulae Nos 1, 2 and 3,[4] better known as Formula 1, Formula 2 and Formula 3 respectively. It remained current through to 1981.[5]
