Group C was a category of auto racing, and was introduced into sports car racing by the FIA (the governing body of World motor racing) during the early 1980's.

Initially, the World Sports Prototype Championship was dominated by Porsche with their 956/962 Group C sports car, but soon the series was developing interest amongst manufactures who were either new to the World of sports car racing or who had been out of the game for a while.

The best days of the World Sports Prototype Championship and the Group C race cars that contested the series were towards the end of the 1980's, when a whole host of manufactures were represented by their entries into the World's premier sports car race series, a series which included as one of its rounds the 24 hours of Le Mans.

The Group C sports prototypes were some of the best racing machines ever created, and produced some classic racing. They are now starting to appear occassionally at historic racing events, although could probably outpace a lot of the newer machinery.

Some examples of Group C race cars are as follows:

Aston Martin AMR-1; Cougar-Porsche C22S, C245; Jaguar XJR-6, XJR-8, XJR-9, XJR-11, XJR-12, XJR-14; Mazda 767B, 787, 787B; Mercedes C9, C11, C291; Nissan R89C, R90CK; Peugeot 905; Porsche 956/962; Spice Ford Cosworth SE88C, SE89C, SE90C; Toyota 89CV, 90CV Ford Falcon XD, XE

These cars are also starting to appear in racing games such as Gran Turismo 4, in which some of the above are featured.
