The RS Spyder (Type 9R6) is a racing car designed by Porsche to compete in Le Mans Prototype Class 2 (LMP2) racing. The car takes its name from the legendary 550 Spyder of the 1950s (combined with Porsche's common "Renn Sport" designation). The car marked Porsche's first return to the top level of sports prototype racing since the firm abandoned its Porsche 911 GT1 Le Mans prototype in 1999.
The RS Spyder made its debut in the final event of the 2005 American Le Mans Series (ALMS) at Laguna Seca winning its class. Since then the RS Spyder has won the ALMS LMP2 Championship in 2006, 2007 and 2008 and took class honours at Le Mans in 2008 and 2009. The outright victory at the 2008 12 Hours of Sebring was the first major victory for Porsche in endurance racing for five years and it was also the first time in 24 years that the non-premier class won the 12 Hours of Sebring overall
The RS Spyder was designed completely in-house by Porsche engineers. The chassis is a rigid carbon fibre monocoque with both the engine and transmission being integral stressed members. The 3.4 litre 90-degree V8 racing engine was designed from scratch as was the six-speed electro-pneumatic sequential gearbox. Braking is via six-piston caliper carbon-fibre brake mounted on suspension controlled by four-way, spring/damper units activated by pushrods with adjustable torsion-bar springs. The car has a dry weight of 825 kilograms (1,820 lb)in 2010 specification but was initially 750 kilograms (1,700 lb).
Since its introduction in 2005 the engine, which initially produced 478 horsepower (356 kW) has been developed and modified to meet the changing regulations of both the ALMS and the ACO. For 2008 the engine developed 503 horsepower (375 kW) using direct fuel injection and 440 horsepower (330 kW) in 2009-spec with air restrictor limitations.
