Porsche 911 GT3 RS 4.0

The 911 GT3 RS, one of Porsche’s most popular, coveted and successful track-inspired production cars, has been given a final, thrilling injection of thoroughbred motorsport technology resulting in the 2011 Porsche 911 GT3 RS 4.0. Limited to 600 vehicles worldwide, the 911 GT3 RS 4.0 brings together in a sports car the attributes that have made the Porsche 911 GT3 a consistent winner on the race track. The motorsport-derived 4.0-liter engine, already the highest displacement 911 engine ever, also features the highest per-liter output — 125 horsepower (hp) per liter — from a naturally aspirated Porsche flat-six engine. The engine uses forged pistons, the connecting rods are fashioned from titanium, and the crankshaft has been lifted unchanged from the 911 GT3 RSR race car. It achieves its maximum power of 500 hp at 8,250 rpm. Maximum torque of 339 ft/lbs is reached at 5,750 rpm.
