Announcing a very special limited edition, Porsche will unveiled a new variant of the infamous 911 GT3 RS in July. Limited to 600 vehicles worldwide, the 911 GT3 RS 4.0 takes the attributes that have made the Porsche 911 GT3 a winner on the racetrack and transferred them to the GT3 road car program.
For example, the engine's crankshaft has been lifted unchanged from the 911 GT3 RSR racer's six-cylinder engine, while the connecting rods are titanium.
The flat six 4.0-liter engine, the biggest ever fitted in a 911, is also its most powerful naturally aspirated engine with 125hp/liter. It achieves maximum power of 500hp at 8250rpm and delivers maximum torque of 340 lb-ft at 5750rpm. The performance translates to a Nurburgring-Nordschleife lap time of 7:27 minutes.
The 911 GT3 4.0, available exclusively with a six-speed manual transmission, sprints from 0-62mph in 3.9 seconds and, with its gearing designed for the circuit, takes it 124mph in under 12 seconds.
In order to best exploit the increased power, the chassis hasbeen revised. This includes the Porsche Active Suspension Management (PASM), which has been recalibrated, while the rear axle now features additional ball-joints for greater control.
Weight reduction has also been address. As a result, the car is equipped with lightweight seats, carbon fiber hood and front fenders, plus plexiglass rear windows and even low-mass carpets! All this means the two-seater's on-road weight is just 3000 lb, delivering a power-to-weight ratio of 368hp/tonne.
The limited edition 911 is painted Carrara White as standard. Trademark characteristics are the wide track, low ride height, large rear wing with new side plates, central twin tailpipes and improved aerodynamics. For example, the lateral front air deflection vanes on the side of the front bumper, known as 'flics', are making their first appearance on a production Porsche. By creating extra downforce on the front axle, they work with the rear wing to balance the aerodynamic forces exerted on the car. As a result, these devices create an additional 420 lb of downforce at top speed, pushing the 911 GT3 RS 4.0 onto the road.
Inside, the 911 GT3 RS 4.0 features carbon fiber bucket seats covered in black leather/red Alcantara with 'RS 4.0' in red on the headrests. The steering wheel and gearshift lever are also trimmed in Alcantara with red stitching. Carbon fiber door entry guards with 'RS 4.0' logos are fitted to each sill, and the dashboard trim strip is carbon fiber with a 'RS 4.0' logo.
As is characteristic of the 911 GT3 RS, the Clubsport package - comprising a half-rollcage, seatbelt harnesses, fire extinguisher and battery cut-off switch - is a standard feature of the 4.0 model.
