In order to exploit the scope provided by the LMP2 regulations (Le Mans Prototype 2) to the full, Porsche has completely revamped the RS Spyder. The new design ensures that engine, transmission, chassis, suspension and aerodynamics combine to produce a harmonious overall package. In the interests of optimum driving dynamics, the vehicle concept focuses on the lowest possible centre of gravity, high agility and good traction.
The RS Spyder was the dominant vehicle in the 2007 American Le Mans Series (ALMS), demonstrating outstanding stability and notching up 11 wins in the 12 races, including 8 overall wins.
The RS Spyder has undergone a detailed revamp for the 2008 season. The main focus was on fine-tuning the aerodynamics and the engine. The V8 racing engine developed for long-distance use continues to generate 478 hp with the prescribed air-flow limiter on the basis of a displacement of 3.4 litres. The fuel consumption has been further optimised and the engine has been adapted even more effectively to the E10 fuel containing 10% bioethanol which is required in the ALMS.
The regulations also necessitated additional modifications. As a result of these measures, the LMP2 minimum weight has been increased by 25 kg (ALMS) and 50 kg (LMS and Le Mans) and the tank capacity has been reduced by 10 l for LMS and Le Mans, though not for ALMS.
