Video: Porsche 911 GT2 RS Explained image

The 2011 Porsche 911 GT2 RS is the crown jewel of the 997 portfolio and complete the lineup.

Output on the car’s twin-turbocharged 3.6-liter flat-6 engine has jumped to 620 horsepower, with power delivered to the rear wheels through a six-speed manual gearbox.
The new Porsche 911 GT2 RS has a weight-to-power ratio of just 2.21 kilos per horsepower, by far the best power/weight ratio in its class.

The GT2 RS gets some additional hardware improvements, including wider light-alloy wheels and new tires (245/35ZR19 in front and 325/30ZR19 in the rear), composite ceramic brakes, adaptive suspension management, specific stabilizer bars and engine mounts, plus a recalibrated stability management system that enables the driver to individually switch off stability- and traction-control functions.
