Based on the Porsche 930, the Porsche 935 was produced as a racing car with a 6-cylinder boxer turbo engine from 1976 to 1981.

It was used by the Porsche works team in the World Sportscar Championship from 1976 to 1978. Jacky Ickx and Jochen Mass were the winners in the first race in Mugello. The duo gained the Sportscar Champion title in 1976 with 3 victories and two second positions in 6 races.

Private teams entered the racing car in the World Sportscar Championship and DRM (Deutsche Rennsport-Meisterschaft) from 1977 to 1982. The 935 was still participating in the North American IMSA-GT racing series up until 1986.

Porsche won the World Sportscar Championship four years in succession from 1976 to 1979 with the 935, and Rolf Stommelen and Klaus Ludwig gained the championship title in 1977 and 1979 respectively in a Porsche 935 at the DRM. At Le Mans, Klaus Ludwig in the Kremer Team won an overall victory in 1979 ahead of two further 935’s, and Porsche garnered the championship title in the GTX and GTP class in the IMSAGT series from 1978 to 1982.

Consequently, the Porsche 935 is still regarded today as one of the most
successful near-series racing cars of all time.
