The Porsche 962 was introduced in 1984 a variant of the developed in 1982 for the FIA Group C Porsche 956, which also fulfilled the provisions of the American IMSA racing series. The new chassis could be used by teams in both series, with group C compliant technique called Porsche 962C.
The type 956 did not meet the American rules in two points. The IMSA called for security reasons, not least due to severe leg injuries in the former Formula 1 that pedals are mounted behind the front axle, Porsche fulfilled by bringing forward of the front axle and thus longer wheelbase. Also the aluminum monocoque has been reinforced by a roll cage made of steel. In addition, had to limit costs of the water-cooled twin-turbo engine of the 956 replaced the 935 coming from the tried and true Porsche air-cooled engines with twin turbochargers, but it was no use restriction as in the World Sportscar Championship for Group C.
Depending on the application at the IMSA race, or Group C World Cup, the Porsche 962 was or 962C equipped with appropriate motors. The rules changed over the years, the engine capacity grew from 2.8 to 3.3 liters; Water cooling was allowed.
After 27 copies of the 956, Porsche built 962 from a total of about 90 race cars, also the 962 teams have some fundamentally modified or used on the 962 -based own designs to make the chassis stiffer and safer and to improve aerodynamics. In the eight years from 1984 to 1991 around 54 wins and numerous championships were retracted. Thus, the 962 is considered the most successful racing car, although the Porsche works in favor of the customer withdrew from the sport. In the late 1980s, although the dominance was the 962 broken by the works teams of Mercedes, Jaguar, Nissan and Toyota, but it was still numerous 962 in use, were prescribed to Formula 1 engines, whereupon the World Sportscar Championship due to the high costs has been set. But even then, in 1993 at Road America and 1994 in Le Mans, won the 962 race yet. An open version won the 1995 Daytona.
Due to the many built copies and the lost ability to win big races, some 962 were converted for road use and later sold under the name Dauer 962 LM. This Jochen duration could obtain an authorization as Gran Turismo racing cars and 1994 surprise win at Le Mans since there only GTs were admitted. Another goal pursued by the Australian racing driver Vern Schuppan, the road-going 962 also brought under the name Schuppan 962CR on the market and thus wanted to enter the market of super sports cars. However, the motor ( the 3.3 -liter version ) with the original, this individual productions only had more in common.
Even though the Porsche 962 was no direct successor, can the Porsche 911 GT1 from 1996 built in the broadest sense designate as his successor, as the GT1 - especially in the GT1 '98 version used from 1998 - many technical and aerodynamic similarities to the group C Renner 962 has. So both cars have not only a mid-engine, but even in many parts of identical construction aggregate. The engine block, the mixture preparation and the cylinder cooling are identical. The chassis of the GT1 was only a fundamental evolution of the super - sophisticated 962er landing gear.
The Porsche 962 was produced and used from 1984 to 1991:
