Having unveiled the 911 GT3 RS in Geneva, Porsche has now taken the wraps off the racing variant. Dubbed the 911 GT3 R, it comes with a lightweight body utilizing aluminum-steel and carbon-fiber composites, and boasts a 8.3-cm longer wheelbase than the outgoing racer, giving it an optimized center of gravity, which is further aided by a centrally-positioned radiator and the nixing of side radiators.

Aerodynamics have been improved thanks to wheel arch air vents and a two-meter wide rear wing, while power comes from the same 4.0-liter flat-six as the road-going GT3 RS. Featuring direct gasoline injection operating at pressures up to 200 bar, and variable valve timing, output is rated at 500 hp, that's sent to the rear via a sequential six-speed constant-mesh transmission. Stopping power comes from six-piston racing calipers and 380-mm steel brake discs up front, and four-piston calipers at the back. Improved safety features include removable doors and side windows and a larger escape hatch in the roof. A new racing bucket seat also provides the pilot better protection. The Porsche 911 GT3 R is available now priced from 429,000 Euros.
