Group C Prototypes

Lore & Background

Group C was introduced in 1982 as a fuel-efficiency formula that limited the amount of fuel each car was allowed. Although it was later phased out, fuel economy remains important as new fuel sources reduce the time spent during pit stops.

In Their Own Story

The rain fell hard on the Mulsanne Straight, turning the tarmac into a mirror that reflected the blinding glare of headlamps. Inside the cockpit of a Porsche 962, the driver gripped the wheel, feeling the vibration of the twin-turbo flat-six engine fighting against the wet grip. The fuel gauge was critical; one more lap without lifting off the throttle could mean running dry before the final sunrise. As he approached the Dunlop Curve, the roar of an Audi R8C echoed behind him, its rotary engine screaming a different note in the symphony of endurance. In this moment, under the floodlights of Le Mans, it wasn't just about speed—it was about survival.
