Based on the 911 GT3 RS production sports
car, Porsche has designed a customer sport race car for GT3 series around
Porsche has paid special attention to lightweight design, better aerodynamic efficiency, reducing consumption, improved handling, further optimized safety as well as lowering service and spare parts costs.
Adopted from its production sibling, the 911 GT3 R features the distinctive double-bubble roof, and the wheelbase which had been lengthened by 8.3 centimeters compared to the previous generation. This ensures a more balanced weight distribution and more predictable handling particularly in fast corners corners in comparison to the previous GT3 R.
The new Porsche 911 GT3 R will be delivered from December 2015.
The aerodynamics of the 911 GT3 R follows the example of the road car. The distinctive wheel arch air vents on the front fairings increase downforce at the front axle. Measuring two meters in width by 40-centimetres in depth, the rear wing lends aerodynamic balance. From its 911 RSR big brother, the GT3 R has adopted the concept of the centrally-positioned radiator. By eliminating the side radiators, the position of the center of gravity was improved, the radiator is better protected against collision damage, and the venting of hot air through louvers in the front cover was enhanced.
Powering the new 911 GT3 R is a four-liter flat-six unit which is largely identical to the high-performance production engine of the road-legal 911 GT3 RS. Direct petrol injection, which operates at pressures up to 200 bar, as well as variable valve timing technology ensure a better use of fuel.
Power from the rear engine is transferred to the 310 mm rear wheels via a Porsche sequential six-speed constant-mesh gearbox. As in the GT road-going models of the 911, the driver changes gears via shift paddles conveniently positioned on the steering wheel.
