For 2013, 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 bird’s eye perspective, the numbers 50 and 911 are visible. These stand for 50 years of the Porsche 911.
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 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.
The center of gravity is also significantly lower than that of its predecessor. The front and rear mudguards, front and rear lids, doors, underbody, wheel arches, rear wing, dashboard and center console are constructed from carbon fiber. 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.
