In force from 1982 to 1993, the Group C regulations led to the creation of legendary cars that wrote some of the most glorious pages in the history of the Le Mans 24 hours and the Endurance World Championship. In the early years the Porsche 956s dominated despite stout resistance from the Lancia LC2s. Then the competition gradually became stronger with the momentum generated by the arrival of Jaguar, Mercedes-Benz, Toyota, Nissan and Mazda when it reached its apogee. In addition to the major manufacturers, constructors like Cougar, Dome, Rondeau, Spice and WM were able to shine thanks to a clever interpretation of the very liberal regulations based on strict fuel consumtion limits. The fabulous Group C epoch ended in the early 90s after a brief period of cohabitation with the 3.5 sports prototypes (Peugeot 905, Jaguar XJR-14, Toyota TS010, etc.). It remains a true golden era for many endurance specialists.
