The series ventured outside West Germany for the first time, replacing the traditional Hockenheimring event with a race at the Silverstone Circuit in Great Britain. The Silverstone round allowed many competitors from the BRDC Sportscar Championship to compete alongside the Supercup. The other four events of the series remained in their calendar positions.| Rnd | Event | Circuit | Location | Date | C1 Winning Driver | C2 Winning Driver |
