2012 Porsche 911 GT3 RSR reveals extensive modifications

Article by Christian A., on November 4, 2011

Porsche unveiled today the 2012 911 GT3 RSR, a new version of its popular racing car which received extensive modifications. The first visual impact with the car shows the changes to the body: the width of the new GT3 RSR has grown by 48 millimetres. Under the hood, the six-cylinder boxer engine with a four-litre capacity delivers 460 hp (338 kW) and drives the 310 millimetre wide rear wheels.

The diameter of the front wheels has now been increased by 30 mm, measuring 680 millimetres. As expected, the engine is mated to a sequential six-speed gearbox operated via paddle shifts on the steering wheel.

Regarding the design, the nose and rear panels are adapted to the flared front and rear wheel arches. The aerodynamic concept is now complemented by a new ducting of the intake air. Openings in the rear side sections now replace the air scoop on the engine hood, which is very similar to the 911 GT2 RS street sports car.

According to Porsche, the 911 GT3 RSR can be raced 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 and in other series and races. Regarding the price, this car will be available from January 2012 and will cost 498,000 Euro plus value added tax of the respective countries.

“Our customer teams can expect a technically mature, high performance race car with which they will be highly competitive at international long distance races,” assures Hartmut Kristen, Head of Porsche Motorsport. “Our test programme on various international race tracks is currently running at full speed. We are very pleased with the car’s performance and driveability.”

The latest 911 Carrera from Porsche is appearing to be the best example of what may be the biggest development steps in its long history. While this may indeed be a classic sports car, an estimate 90% of its parts have either been redeveloped or redesigned for this new generation version. Its body makes use of new lightweight materials with the suspension systems redesigned and the efficiency of the drivetrain improved. The new 911 Carrera is also equipped with the enhanced Porsche Intelligent Performance.

Proof that almost everything in the new 911 Carrera is new is that driving dynamics is better as fuel consumption, and even emissions, are reduced by as much 16%, ensuring a practical use on a daily basis. Even the style is new and this is clear no matter where it is viewed from. Take the sides for instance. With its alloy wheels being larger and the fact that the windscreen follows a more convex shape, it gives it that characteristic that is more coupe-like.

As expected, with the front end being revised, it is now wider and placed on it are the new headlights as well as the side air intakes that are now larger. Going to the back, the spoiler in the rear is both wider and more extensive, highlighting its greater power.

Rounding up the changes on the rear end are the lights which still utilize LED technology but have been redesigned and made narrower. With all of these different changes plus the aerodynamic features being optimized, lift is lowered significantly while good Cd value is retained. As mentioned already, it comes with the latest version of the Porsche Intelligent Performance.

For both the design of the new 911 Carrera and its proportions, they have been developed in line with the technology. It biggest change is the wheelbase, which is now longer by 100 millimeters (3.94 inches), with the body also having its overall length extended by 56 millimeters (2.20 inches). However its overhangs have been made shorter with the front being shorter by 32 millimeters (1.26 inches) and the rear by 12 millimeters (0.47 inch).

The roofline has been changed as well considering that when compared to the previous generation, it is lower by 7 millimeters and when compared to the Carrera S, it lower by 6 millimeters. Even with all these changes, the feature that is still the same is the maximum headroom. Versions that have the sunroof have the headroom increased by as much as 15 millimeters.

By the way, this particular sunroof is the one that features an electric tilt/slide. Still, the new 911 Carrera remains to be a compact sports car (actually the most compact in its segment), with total length at 4.5 meters (176.81 inches) and overall width at 1.8 meters (71.18 inches). Without a doubt, the lightweight aluminum-steel body mixed in with a host of new parts and functions gives the new 911 Carrera the driving dynamics and efficiency that customers expect.
