NEW PORSCHE 911 GT3 RSR FEATURES NUMEROUS UPGRADES
World’s most successful GT race car enhanced with revised
aerodynamics, suspension and engine
December 11, 2010 --- At the “Night of Champions” party held at the Porsche R&D Centre in Weissach to mark the end of the motorsport season, the 2011 version of the world’s most successful GT race car celebrated its international premiere.
The Porsche 911 GT3 RSR enters the new motorsport season with extensive modifications. Further development prioritized newly designed aerodynamics at the front and rear as well as changes to the suspension kinematics and the engine.
The 4.0-litre, six-cylinder boxer engine now delivers 455 hp at 7,800 rpm, five horsepower more than its predecessor. The power increase results from an engine management system which adapts even better to different fuel grades, as well as a redesigned exhaust system and a modified air intake housing. Moreover, the drivability of the famously efficient engine has undergone further improvements. Maximum revs remain unchanged at 9,400 rpm.
At the front of the car, a new front lip provides higher downforce at the front axle. The front wheels are now larger, with the rims growing from 11 to 12 inches wide, providing additional front-end grip and reducing understeer. The position of the rear wing and the shape of the wing mounting were also optimized and harmonized with the design of the new rear fairing with additional air outlet louvers. The rear lid was also redesigned for optimized air ducting. Like the 911 GT3 Cup and the GT3 R, the RSR is now equipped with the LED rear lights taken from the latest 911 road-legal cars.
The 911 GT3 RSR joins the 911 GT3 R and the 911 GT3 Cup as the top model of Porsche Motorsport’s product range. The successful long-distance racer from Weissach can be ordered a price of 410,000 Euro plus country-specific value added tax. All 2011 modifications are also available as a kit for GT3 RSR cars from the 2010 season.

Interesting to see that the 4.0L engine makes 455hps, while the street car 3.8L from the RS is rated at 450hps.
And the 4.0L is allowed to rev up to 9,400rpm as well.
So either the 455hps rating is probably very conservative? Or it is simply tune for more torque and not much power w/ the bigger displacement?
