2011 Porsche 911 GT3 RS 4.0 Coupe

The 911 GT3 RS, one of Porsche's most popular track-inspired production cars, has been given a final injection of motorsport technology resulting in the 2011 Porsche 911 GT3 RS 4.0. The 4.0-liter engine, already the highest displacement 911 engine ever, also features the highest per-liter output - 125 horsepower per liter - from a naturally aspirated flat-six engine. Using forged pistons and titanium connecting rods it achieves its maximum power of 500 horsepower at 8,250 RPM. Maximum torque of 339 ft/lbs is reached at 5,750 RPM.

As a two-seater it weighs 2,998 pounds due to lightweight components such as carbon-fiber bucket seats, front fenders and front lid, and 'weigh-optimized' carpets. The lateral front air deflection vanes, a first on a production Porsche, increase down force on the front axle. Aided by a steeply inclined rear wing, aerodynamic forces exert an additional 190 kg, enhancing the grip to the tarmac. As a result, it can lap the Nurburgring in 7 minutes and 27 seconds, print from zero-to-sixty mph in 3.8 seconds, hit the 125 mph mark in less than 12 seconds, and proceed on to a top speed of 193 mph.

Only 600 GT3 RS 4.0 were produced. This example is number 475 of 600, delivered in late December of 2011, and is believed to be one of just 125 examples of the GT3 RS 4.0 in the United States. Most cars were delivered in Carrera White with the RS 4.0 graphics and striping package as created by the Weissach Factory Designers.
