The new 911 RSR race car, running in the WEC LM-GTE class, is characterized by significant lightweight design and sophisticated aerodynamics. The exceptional vehicle styling honors a very special anniversary: From a birds 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 will exclusively field two Porsche 911 RSR race cars in the World Endurance Championships 2013 season including the 24 Hours of Le Mans. The car will not run in a North America series for 2013.
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 GT3 RSR (type 997). As with the production vehicle, the wheelbase grew by about ten centimeters, or four inches. 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 optimized in detail.
One of the priorities in the development of the new 911 RSR was the more evenly balanced weight distribution. The center of gravity is also significantly lower than that of its predecessor. Carbon fiber 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 center 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 911 GT3 road going models.
The look of the new 911 RSR is dominated by the flared mudguards and the deep cooling air intakes at the front. With the new air ducting, the radiator is now centrally-located in the front and even more effective than in the previous model. At the same time, the cockpit air conditioning became more efficient. The quick-change concept of the body parts was specially adapted for endurance racing, allowing for easier maintenance and shorter repair times. The front end, front lid and rear panel are fitted with quick release systems and can be replaced within seconds.
