Built to homologate the 2011 GT3 RSR racecar, the RS 4.0 is fitted with the 3996cc engine which raises power output from roughly 444 to 500 bhp. It is easily identified by its new wings and front winglets just ahead of the front wheels.
Limited to just over 600 examples worldwide, the Porsche 911 GT3 RS 4.0 is an exclusive road car which is ideally suited for hardcore track use. The flat-six engine’s crankshaft has been taken directly and without modification from the 911 GT3 RSR racing car’s engine, while the connecting rods for the forged pistons are fashioned from titanium.
The 4.0 litre displacement engine is the biggest 911 model line engine ever, and it is also the most powerful naturally aspirated engine with 125 hp/litre. It produces its maximum output of 500 horsepower at 8,250 rpm. At 5,750 rpm the maximum torque is achieved with 340 lb-ft.
