Porsche has officially announced details on the new GT3 RSR that will be used in the 2012 racing season. Compared to the current model, the new GT3 RSR has grown by 48 millimeters and has been built to conform to the A.C.O. "LM" GTE regulations.
The 2012 GT3 RSR is powered by a 4.0 liter six-cylinder boxer engine that delivers a total of 460 HP (up 5 HP over the 2011 model). The engine comes equipped with a mandatory air-restrictor and is mated to a six-speed gearbox. The gearbox is operated via paddle shifts on the steering wheel that send the power to the rear wheels, which have grown to 310 millimeters in width. Also compared to the previous model, the front wheels have increased by 30 mm to measure 680 millimeters.
Exterior changes are minimal, but still present. The nose and rear panels have been adapted to the flared front and rear wheel arches, while openings in the rear side sections replace the air scoop on the engine hood.
The new 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, and the International GT Open starting in the 2012 season. Deliveries will begin in January 2012 and prices will start from 498,000 Euro (plus VAT ), or about $685,000 at the current exchange rates.
