Porsche 911 GT3 RSR is a GT race car built for endurance racing. For the 2011 season, Porsche unveiled a new version of the Porsche 911 GT3 RSR with extensive modifications. Priority in the development of the new version was given to the newly designed aerodynamics at the front and rear, changes to the suspension kinematics and to the engine.

Clearly visible are the modifications to the front. A new front lip provides higher downforce at the front axle. The front wheels are wider with the rims growing from 11 to 12 inches giving additional grip and less of an understeering tendency. The position of the rear wing and the shape of the wing mounting also underwent optimisation and were adapted to the new rear fairing with additional air outlet louvers. The rear lid was also redesigned for optimised air ducting. Like the 911 GT3 Cup and the GT3 R, the RSR is also equipped with the LED rear lights taken from the 911 road cars.

The Porsche 911 GT3 RSR is powered by a 4.0-litre, six-cylinder boxer engine. It delivers 355 kW (455 hp) at 7,800 revs, five horsepower more than its predecessor. The power increase results from an engine management system which adapted even better to different fuel grades, as well as a redesigned exhaust system and a modified air intake housing. Moreover, the driveability of the famously efficient engine has undergone further improvements. The maximum engine speed is 9,400 rpm.

The price of the Porsche 911 GT3 RSR was 410,000 Euro plus country-specific value added tax.
