Format
The Supercup would employ a sprint format for all of its races, each race lasting approximately one hour although later events were extended to near an hour and a half. These short distances meant that unlike the endurance races seen in the World Championship, Supercup teams would not be required to change drivers during the course of an event. Each season consisted of five rounds, all held in West Germany with the exception of a Silverstone round in 1989. Popular circuits included the Nürburgring, Hockenheimring, Diepholz airfield, and the Norisring 200 Miles event.
The cars ran rules nearly identical to the FIA's Group C category, broken into C1 and C2 classes. The larger C1 class was dominated by both factory and customer Porsche 956s and 962Cs, as well as efforts from the Jaguar, Mercedes-Benz, and Nissan factory teams. C2 consisted of teams running engines limited in capacity to produce less power than the C1 cars but also weighed less. Although two classes ran, only a single championship was held.
