Rolf Stommelen
Each championship had seven races, with only Dijon hosting both on the same weekend, while on two other weekends, the races were even run in different countries, which forced Porsche to divide its resources. Jacky Ickx and Jochen Mass were the main drivers, when the F1 schedule permitted. Rolf Stommelen, who was recovering from his bad crash in the 1975 Spanish GP, was the backup, along with Manfred Schurti.
