The RS Spyder has been developed exclusively in-house at Porsche - this being the only way of ensuring that engine, transmission, chassis and aerodynamics combine to create a harmonious overall package. The technology in the RS Spyder has been consistently adapted to the conditions required under the LMP2 rules (Le Mans Prototype 2).
The RS Spyder has been adapted to comply with the changed rules for the 2009 season. This affects both the aerodynamics due to the 160-cm wide rear wing and the 3.4-litre V8 engine which now generates 478 bhp instead of 440 bhp following the significant reduction required in the size of the air-restrictor.
