Mississauga, Ontario – Porsche has announced the 911 GT3 RS 4.0, a 500-horsepower race-inspired model that will be limited to 600 vehicles worldwide.

The 4.0-litre engine is the biggest 911 engine ever and, at 125 horsepower per litre, is the highest specific output from a naturally-aspirated Porsche flat-six. The crankshaft is unchanged from the 911 GT3 RSR race car and the forged pistons’ connecting rods are made from titanium. The engine makes its maximum 500 horsepower at 8,250 rpm.

Available exclusively with a six-speed manual transmission, the car reaches 100 km/h from a standing start in 3.9 seconds, and 200 km/h in under 12 seconds.

Standard lightweight components include carbon fibre sport bucket seats, front fenders and luggage compartment lid, along with weight-optimized carpets, bringing the car to just 1,360 kilograms including a full tank of fuel.

The new model will go on sale in Canada in late 2011 starting at $211,100.
