2010 Porsche 911 GT3 RS

The Porsche 911 GT3 RS may have been one of the best road-legal sports cars on the market, but that didn't stop Porsche from making it even better. For 2010, Stuttgart tweaked GT3 RS, giving it more power, better handling, and reducing its weight, making it an even meaner street and track machine.
Starting in the back, Porsche punched-out the previous GT3 RS's 3.6L naturally aspirated flat-six to 3.8L, resulting in a 15-hp increase for a total of 450 hp. A revised six-speed transaxle features shorter throws and closer ratios for increased performance and, like the outgoing model, the entire exhaust system continues to be built from lightweight titanium.
Moving forward, Porsche widened the front and rear tracks to fit nine-inch-wide wheels in front and 12-inch-wide wheels at the rear wrapped in 245/35 ZR 19 and 325/30 ZR 19 tires respectively. Porsche Active Drivetrain Mounts are standard and minimize drivetrain weight transfer in hard cornering.
Other changes include a lowered ride height, a larger carbon-fiber rear wing, new bodywork to reach around the wider tires, new paint and graphics schemes and an optional lithium-ion battery that is more than 22 lbs lighter than a standard lead-acid battery.
The updated Porsche 911 GT3 RS is slated to go on sale in Europe following its Frankfurt debut and in the U.S. next year. In the states, pricing will start at $132,800 before delivery and other charges.
