Porsche has unveiled 2013 Porsche 911 RSR race car that will compete in the World Endurance Championship (WEC) and the Le Mans 24 Hours.
The 911 RSR car follows in the footsteps of its successful predecessor, the 911 GT3 RSR (type 997). It has 460-horsepower, 4.0-litre six-cylinder boxer engine taken from the predecessor and optimized in detail.
As with the production vehicle, the wheelbase grew by about 10 centimeters, or 4 inches. A new wishbone front suspension replaces the previously used McPherson struts.
Another new development is the particularly lightweight racing gearbox. The six gears are selected via paddles on the steering wheel.
The car will not run in a North America series for 2013.
