Porsche 956 (1982) Engine 2650cc H6 TurboENTRANT: Peter HarburgDRIVER: Oeter Harburg The Porsche 956 was a Group C sports-prototype racing car designed by Norbert Singer and built by Porsche in 1982 for the FIA World Sportscar Championship. It was later upgraded to the 956B in 1984.The 956 features a chassis made of an aluminium monocoque, a first for the company, helping to allow the car to meet the 800 kg (1. 764 lb) weight minimum in Group C. The engine is the same as the one used in the Porsche 93681, the Type-935 2.65 L turbocharged Flat-6, producing approximately 635 hp (474 kW) (originally developed as an Indycar engine; hence the cubic capacity used). The very first dual clutch gearbox was also designed for the 956, mated to a traditional 5-speed manual.The 956 made its debut at the Silverstone 6 Hour race, the second round of the World Championship for Makes with Jacky Ickx and Derek Bell driving for the factory. After missing the following round at the 1000 km Nrburgring for developmental reasons, the IckxBell unit reappeared at the 24 Hours of Le Mans. They led the race for the entire 24 hours, eventually taking the overall win - their third win together. As they had already won in 1981 with a Porsche 936 that had used an early version of the 956 engine, their car had start number 1. The two other factory 956 followed them, so the three factory Porsches finished 1-2-3 in the order of their starting numbers.This is the car that finished in third driven by Hurley Haywood (USA), Al Holbert (USA) and Jurgen Barth (D) Shot the Goodwood Festival of Speed 30:06:2012 Ref: 87-411.
