Porsche 911 RSR Shows Pinnacle of Porsche's Customer Race Car Line

This will very likely be the final generation of Porshe's customer race cars based on the 997 chassis. The new 991 chassis will be available worldwide, and Porsche is surely already developing it into a race car ready for purchase by customers. 

So we can look at this year's 911 RSR has the ultimate evolution of the 997. This year's RSR has been widened by 48mm to make it legal in A.C.O "LM" GTE racing. That means this car is capable of racing at the Le Mans 24 Hours, the FIA World Endurance Championship, the Le Mans Series, the American Le Mans Series as well as the International GT Open.

The RSR is powered by a 4.0 liter flat-six engine producing 460hp (338kW) with a sequential six-speed gearbox controlled by steering wheel-mounted paddles. 

The nose and rear have been modified this year to adapt to the rear fenders. Air is ducted to the engine via openings in the rear wheel flairs as opposed to the engine-mounted scoop on last year's model. 

Deliveries of the car begin in January 2012 with prices starting at €498,000 plus any local taxes.
