1977 saw Porsche's great rival BMW begin to lose interest in the World Manufacturers Championship after the pairs titanic battle during the previous season. Come 1977 and with Porsche themselves campaigning only a few twin turbocharged 'Works' cars, it was left to customer teams to campaign single turbo spec derivatives which were built during the winter of 1976.

Weighing in at 970kg, the customer-spec 935's retained the single turbo Type 930/72 motor as installed in the 1976 works cars.
