The power increase of the four-litre, six-cylinder flat engine in the rear was achieved through optimisation of the intake system. The gearing of the sequential six-speed dog-type gearbox was adapted to the higher maximum output. In order to bring the power to the tarmac safely and to assist race drivers, the 911 GT3 R has featured a sophisticated ex-works traction control since the 2010 model year. An efficient race-ABS assists braking. The new Porsche 911 GT3 R will be delivered to teams around the world from November 2011. The vehicle costs 304,500 Euro plus the value added tax of respective countries. The Porsche 911 GT3 R from the 2010 and 2011 model years can be upgraded to the 2012-spec. An upgrade kit is available from Porsche Motorsport for 43,100 Euro. The 911 GT3 R represents the mid-range of Porsche’s customer racing vehicles. The 911 GT3 Cup, as the top-selling race car in the world, serves as the basis. Ranking above the 911 GT3 R is the 911 GT3 RSR, built for GT2 racing, which competes in series like the American Le Mans Series, the Le Mans Series and at the Le Mans 24 hour race.
