Porsche 911 GT3 RSR with wide modifications

The Porsche 911 GT3 RSR takes off into 2011 with wide modifications. The Porsche 911 GT3 RSR 2011 version of the world’s most successful GT race car celebrated its international premiere at the “Night of Champions” party held at the R&D Centre in Weissach to mark the end of the motorsport season. Priority in the further development of the Porsche 911 GT3 RSR was given to the newly designed aerodynamics at the front and rear, modifications to the suspension kinematics and to the engine.

The 4.0-litre, six-cylinder boxer engine now delivers 455 hp (355 kW) at 7,800 revs, five horsepower more than its predecessor. The power rise results from an engine management system which adapts even better to different fuel grades, as well as a reshaped exhaust system and an altered air intake housing. Moreover, the driveability of the excellently efficient engine has undergone further enhancements. Maximum revs remain unchanged at 9,400 rpm.

A new front lip provides higher downforce at the front axle. The front wheels are now wider with the rims growing from 11 to 12 inches giving additional grip and less of an under steering tendency. The position of the rear wing and the shape of the wing mounting also underwent optimization and were adapted to the new rear fairing with additional air outlet louvers. The rear lid was also reshaped for optimized air ducting. Like the 911 GT3 Cup and the GT3 R, the Porsche 911 GT3 RSR has now been equipped with the LED rear lights taken from the latest 911 road-legal cars.
