The new 2012 Porsche 911 GT3 RSR race cars made their global debut as three U.S. customer teams provided them with their first race track test to prepare for the 60th Anniversary Mobil 1Twelve Hours of Sebring Fueled by Fresh at Florida next month. In the past week, these race cars were spotted in plain white livery as they arrived from the factory.
The range-topping model of Porsche Motorsport's customer racing vehicles will enter the 2012 season with considerable modifications, the most obvious of which are the body revisions. For instance, the new GT3 RSR has become wider by 48 millimeters. The 911 was built to conform to the A.C.O. "LM" GTE regulations.
It is the topmost model in a range of thriving customer sport race cars that are based on the 911 GT3 RS (type 997) street sports car. It continues to power the new 911 GT3 RSR with a highly efficient six-cylinder boxer engine with a four-liter capacity.
It comes with a mandatory air-restrictor that generates 460 hp (338 kW) and drives the 310 millimeter- wide rear wheels. Its front wheels’ diameter was increased by 30 mm to now measure 680 millimeters.
The Porsche sequential six-speed gearbox can be operated with the use of paddle shifts on the steering wheel. Its nose and rear panels are adapted to the flared front and rear wheel arches, similar to the door sill and the wheel arch coverings. Its aerodynamic concept is complemented by a new ducting of the intake air.
The openings in the rear side sections, as known from the turbo variants of the Porsche 911, replace the air scoop on the engine hood, which is reminiscent of the 911 GT2 RS street sports car. These four new 911 GT3 RSRs will compete in the American Le Mans Series. The car could also enter the Le Mans 24 Hours, the FIA World Endurance Championship, and the Le Mans Series. It may even compete in the International GT Open and in other series and races.
