From 1982 until the early 1990s, Group C prototypes competed at Le Mans. The regulations did not specify any engine power output, but only a fixed amount of fuel for the entire race. So, to win, you needed a car that was both fast and fuel-efficient. This gave rise to some of the most legendary racing cars in history. The Porsche 956 and its successor, the 962, dominated the 1980s with a long winning streak. Jaguar, Sauber-Mercedes, Mazda with its screeching Wankel engine, and Peugeot also made Le Mans history. On the long Hunaudières straight, the cars used to reach speeds of over 400 km/h before chicanes were installed in 1990. The images in this collection showcase the racing cars of an era that, for many fans, remains the finest in endurance racing to this day.
