The new Porsche 911 GT3 RSR is ready to race. The top model of Porsche Motorsport’s customer racing vehicles will head into the 2012 season with extensive modifications. Particularly striking at first glance are the changes to the body: the width of the new GT3 RSR has grown by 48 millimetres. Built to conform to the A.C.O. “LM” GTE regulations, the 911 represents the crowning pinnacle of a range of successful customer sport race cars that are based on the 997 type 911 GT3 RS street sports car.
Powering the new 911 GT3 RSR is a particularly efficient six-cylinder boxer engine with a four-litre capacity. With a mandatory air-restrictor, it generates 460 hp (338 kW) and drives the 310 millimetre wide rear wheels. The diameter of the front wheels has increased by 30 mm to now measure 680 millimetres. The Porsche sequential six-speed gearbox is operated via paddle shifts on the steering wheel.
The nose and rear panels are adapted to the flared front and rear wheel arches, as are the door sill and the wheel arch coverings. The aerodynamic concept is complemented by a new ducting of the intake air. 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 very similar to the 911 GT2 RS street sports car.
The new 911 GT3 RSR can be raced at the Nurburgring 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.
