Powering the new 911 GT3 R is a 4-litre flat-6 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 particularly efficient use of fuel. The normally-aspirated engine offers significantly better driveability and a broader usable rev range. Power from the rear engine is transferred to the 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 positioned on the steering wheel.
