Group 7 was a set of regulations forautomobile racing created by theCommission Sportive Internationale (CSI), a division of the modernFédération Internationale de l'Automobile.

There were two distinct sets of Group 7 regulations:

• Group 7 two-seater racing cars (1966 to 1975)
• Group 7 international formula racing cars (1976 to 1981)

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 earnhomologation. 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.

Although the formula only existed for ten years, Group 7 was embraced by several series around the world, with theSports Car Club of America running itsUnited States Road Racing Championship for Group 7 cars from 1966 to 1968. ItsCanadian-American Challenge Cup, better known as Can-Am, was also open to Group 7 cars from 1966 to 1974. In Europe, theNordic Challenge Cup ran in 1969, replaced by theInterserie in 1970 before the series later adopted aFormula Libre format. Early editions of theJapanese Grand Prix were dominated by Group 7 cars built by Japanese manufacturers.

Many manufacturers became involved in Group 7, withMcLaren andPorsche building the most dominant cars in the category. ManufacturersLola,Chaparral,Ferrari,BRM,Shadow,Nissan,Toyota, andIsuzu all built Group 7 cars, whilebig-blockChevrolet andFord motors were the engines of choice throughout the world.

The formula was current through to 1975,^[3] with two-seater racing cars defined underGroup 6 regulations from 1976.^[4]

From 1976 the FIA used the Group 7 designation forinternational formula racing cars.^[4] The new Group 7 encompassed International Formulae Nos 1, 2 and 3,^[4] better known asFormula 1,Formula 2 andFormula 3 respectively. It remained current through to 1981.^[5]
