The Group C regulations, in force between 1982 and 1993, led to the production of legendary cars that wrote some of the most glorious pages in the history of the Le Mans 24 Hours and the Sports Car World Endurance Championship.
Early on, the Porsche 956s dominated despite stiff opposition from the Lancia LC2s, and then in 962 configuration came up against much tougher rivals with the arrival of Jaguar, Mercedes-Benz, Toyota, Nissan and Mazda. Alongside the major manufacturers small constructors like Cougar, Dome, Rondeau, Spice and WM could still pull off the odd coup thanks to an intelligent interpretation of the regulations based on strict fuel consumption restrictions. Group C was abandoned in the early 90s after a brief cohabitation with the Sport 3.5s (Peugeot 905, Jaguar XJR-14, Toyota TS010, etc), but that era is still considered as the Golden Age of endurance racing by the majority of specialists of this branch of motor sport.
Le Mans Classic is held every two years and it gives Group C Racing competitors the opportunity to take part in a 45-minute race on Saturday midday as a prelude to the main event. Given the demanding nature of the circuit for both cars and drivers and the fact that the meeting takes place every two years, competitors must take part in two qualifying races to validate their entry for the 2021 Le Mans Classic on 1-2-3-4 July. They can compete in two qualifying events in the 2020 or 2021 Peter Auto series. Participation in the Daytona Classic and Sebring 12 Hours Classic races is also accepted as the Group C technical specifications are the same in the competitions organised by Historic Sportscar Racing and Peter Auto.
