Group C was a category of motorsport, introduced by the FIA in 1982 and continuing until 1993. Group C applied to sport's car racing , with Group A for touring cars and Group B for Gts.
It was designed to replace both Group 5 special production cars (closed top touring prototypes like Porsche 935) and Group 6 two -seater race cars (open-top sportscar prototypes like Porsche 936). Group C was used in the FIA's World Endurance Championship(1982–1985), World Sports-Prototype Championship (1986–1990), World Sportscar Championship (1991–1992) and in the European Endurance Championship (1983 only). It was also used for other sports car racing series around the globe (All Japan sport's prototype championship, Supercup, Interserie). The final year for the class came in 1993.
Broadly similar rules were used in the North American IMSA Grand touring prototype series (GTP).
By 1989, the Group C seres popularity was nearly as great as F1 races. When C1 cars were found to be breaking over the 400 kilometers per hour mark at Le Mans'Mulsanne Straight — the WM- Peugeot recorded the highest 407 km/h (253 mph) during qualifying for the 1988 event — the FIA revolutionized the class by attempting to turn it into a formula series to replace the C2 category (after they proved to be unreliable at endurance races). The new formula restricted the performance of cars built to the original rules (such as the Porsche 962 used by many privateers) and benefited teams using F1-sourced 3.5 L engines — these latter teams being effectively the large manufacturers alone, as the new formula cars were more expensive than the C1 cars. What followed was the quick downfall of Group C, as the new engines were unaffordable for privateer teams like Spice and ADA. A lack of entries meant the 1993 Championship was canceled before the start of the first race. However, the ACO still allowed the Group C cars to compete (albeit with restrictions) at 24 Hours of Le Mans. Nevertheless, the race still witnessed protests against the new state of affairs, as spectators placed cloth banners in fences expressing their feelings.
The 1994 24 Hours of Le Mans was the last one in which Group C cars were permitted. A new category formed especially by race organizers also saw modified Group C cars without roofs. In fact, a former C1 car disguised as a road-legal GT car which was entered in the GT1 category, the Dauer 962 Le Mans, and won the race after transmission problems by a leading Toyota94C-V. The 962 was subsequently banned; the Toyota was later given a special dispensation to race in the Suzuka 1000km, and a few C1 racers were allowed to compete in the newly formed Japanese GT championship — this would be its final year of competition. Many of the modified open top Group C cars continued to compete until they wrecked, broke, or retired out of competitiveness; notable among these was the Porsche WSC-95 which won the 1996 and 1997 Le Mans races, using the monocoque of the Jaguar XJR-14 and Porsche 962 mechanicals (engine, transmission, etc.).
So here is a list of the most legendary cars!Such a poetry....... not the most safe era of racing but certainly one of the greatest!
