Porsche 935
racing automobile (1976-1981)
The Porsche 935 is a race car that was developed and manufactured by German automaker Porsche. Introduced in 1976 as the factory racing version of the 911 (930) Turbo and prepared for FIA-Group 5 rules, it was an evolution of the Carrera RSR 2.1 turbo prototype, the second place overall finisher in the 1974 24 Hours of Le Mans.
Beginning with the 1977 season, Porsche offered the 935 to customers entering the World Championship for Makes, in the IMSA GT Championship and in the German Deutsche Rennsport Meisterschaft (DRM). The 935 went on to win the 1979 24 Hours of Le Mans overall, and other major endurance races, including Sebring, Daytona, and the 1,000 km Nürburgring. Of the 370 races it was entered, it won 123.
Usually, no other make could challenge the 935, as other manufacturers did not supply customer cars as Porsche did. Each race, at the time, typically featured at least five 935s. The 935 used a 3.3L Type 935 twin-turbocharged flat-six engine which used a mechanical fuel injection system. All of the high performance components combined enabled the engine to have a power output up to 630 kW (845 hp; 857 PS), the engine often suffered turbo lag at low RPM due to the large turbochargers. The dominance of the 935 ended with changes in the FIA rules which came into effect in 1982, replacing the six numbered groups with only three groups, namely A, B and C.
The second generation of the 935 started a limited-production of just 77 units, with customer deliveries in June 2019.
