The Limited Edition Porsche 911 GT3 RS 4.0

Porsche will launch a new variant of the Porsche 911 GT3 RS in July 2011, providing more power and higher performance. The Porsche 911 GT3 RS 4.0 will be limited to 600 vehicles worldwide.

The new model transmits thoroughbred motorsport technology through to its innermost core. The flat engine's crankshaft has been lifted unchanged from the 911 GT3 RSR racing car's six cylinder engine and the forged pistons' connecting rods are made of titanium.

The flat six 4.0 litre engine is the biggest engine in a Porsche 911 ever - it is also the most powerful natural aspirated engine, with 125hp/litre. Maximum power is 500hp at 8,250 revs per minute and maximum torque is 460Nm at 5,750 rpm.

The Porsche 911 GT3 4.0 is available exclusively with a six-speed manual sports transmission, and achieves a 0 to 62 mph time of 3.9 seconds and, with its gearing designed for the racing circuit, takes it to the 124 mph mark in under 12 seconds.

Equipped as standard with light weight components such as bucket seats, bonnet and front wings made of carbon fibre, plastic rear windows and weight-optimised carpets, the two-seater's ready-for-road weight is just 1,360 kg, delivering a power-to-weight ratio of 368 hp/tonne.

The limited edition Porsche 911 is painted Carrara White as standard. Making their first appearance on a production Porsche are the lateral front air deflection vanes - named 'flics'. They create increased downforce on the front axle, and a steeply inclined rear wing brings the vehicle into aerodynamic equilibrium. Aerodynamic forces exert an additional 190kg at top speed.

On the inside, light weight carbon fibre bucket seats come covered in black leather/red Alcantara with 'RS 4.0' in red on the headrests. The steering wheel and gear shift lever are also trimmed in Alcantara with red stitching. Carbon fibre door entry guards with 'RS 4.0' logos are fitted to each door sill and a dashboard trim strip in carbon fibre with a 'RS 4.0' logo runs across the inside of the car above the glovebox lid.

A half roll cage, seat belt harnesses, fire extinguisher, battery cut-off switch are a standard feature of the 4.0 model.

The Porsche 911 GT3 RS 4.0 is limited to 600 examples worldwide and will go on sale in July 2011 priced from £128,466.
