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.
The Porsche 911 GT3 is the sportiest 911, featuring a naturally-aspirated power unit that’s ready and set to take up challenges and prove to the world its enhanced potential. This new sports car is faster, more dynamic, and more powerful than ever.
The development of the new 911 GT3 car comes with a wide range of knowledge in motorsport, making the sports car a supreme performer both on the road and on the track. What’s more, the car reaches a much higher standard in terms of two main qualities: driving dynamics and power.
Additionally, the maximum output of the car’s 6-cylinder, which is now 3.8 liters in size, is 435 bhp or 320 kW. This figure is up 20 bhp compared to that of the previous model. Particularly, the flat-six power unit, which has been carefully upgraded to provide even more muscle and an even better performance, offers significant torque increase at medium engine speeds.
Road performance has also been enhanced, with the new GT3 accelerating to 100 kilometers per hour in just 4.1 seconds, then reaching 160 kmph in 8.2 seconds. The top speed is 312 kmph. Moreover, fuel consumption and exhaust emissions have been significantly reduced.
Lastly, the Porsche 911 GT3 truly stands out with its unique and outstanding design. This has already been the case from the start, when the 911 began as a combination of a thoroughbred production sports vehicle and production-based racing car.
At first glance, you can already tell the new GT3’s impressive qualities, including its new cooling air outlet that borders on the front apron and front lid and that is located between its bi-xenon headlights, now featured as a standard and offering optimized thermal balance. The central outlet, covered by a grid just like the large air intakes in the front bumper’s lower portion, is also a special feature.
