Porsche AG Unveils New 911 RSRÂ Photos

Stuttgart. Porsche has developed a new GT race car for the World Endurance Championship (WEC) and the Le Mans 24 Hours. The new 911 RSR is characterised by consequent lightweight design and sophisticated aerodynamics. The exceptional vehicle styling honours a very special anniversary: From a bird’s eye perspective, the numbers 50 and 911 are visible. These stand for 50 years of the Porsche 911. The Porsche AG Team Manthey works squad exclusively fields two Porsche 911 RSR in the 2013 season.
The new 911 RSR, which is based on the seventh generation of the iconic 911 sports car, follows in the footsteps of its successful predecessor, the 911 RSR (GT3). As with the production vehicle, the wheelbase grew by about ten centimetres. A new wishbone front suspension replaces the previously used McPherson struts. Another new development from Porsche Motorsport is the particularly lightweight racing gearbox. The six gears are selected via paddles on the steering wheel. The 460 hp, 4.0-litre six-cylinder boxer engine was taken from the predecessor and optimised in detail.
One of the priorities in the development of the new 911 RSR was the more evenly balanced weight distribution. The centre of gravity is also significantly lower than that of its predecessor. Carbon fibre played a crucial role in the new design. The front and rear mudguards, front and rear lids, doors, underbody, wheel arches, rear wing, dashboard and centre console are constructed from the very light and strong material. Moreover, all windows are made of particularly thin and light polycarbonate. Also contributing to the weight reduction is the lithium-ion battery known from the GT road-legal models.
