2011 Audi R8 GT - New Photos

2011 Audi R8 GT powered by a modified version of the R8 V10's naturally aspirated 5.2-liter direct-injection engine producing 550-horsepower, while thanks to a series of weight-saving measures that shave about 100kg (220 lbs), the car tips the scales at 1,525 kilograms (3,362 lbs).

The GT is a lighter, more powerful and faster variant of the R8. The Audi R8 GT accelerates from zero to 100 km/h (62.14 mph) in 3.6 seconds and reaches a top speed of 320 km/h (198.84 mph). Changes to the engine electronics coaxed an additional 26 kW from the ten-cylinder, which now produces 412 kW (560 hp) from a displacement of 5,204 cc. The torque curve peaks at 540 Nm (398.28 lb-ft) at 6,500 rpm, 10 Nm (7.38 lb-ft) more than in the production version. The V10 has a specific power output of 79.2 kW (107.6 hp) per liter displacement. Its power-to-weight ratio is 3.70 kilograms (8.16 lb) per kW or 2.72 kilograms (6.00 lb) per hp. The engine redlines at 8,700 rpm.

While the GT also benefits from a modified suspension, larger carbon fiber ceramic brakes, 19-inch forged alloys wrapped in 235/35 tires up front and 295/30 at the back, and numerous aero tweaks that are said to improve downforce.
