620HP Porsche 911 GT2 RS: THE MOST STREET-LEGAL PORSCHE OF ALL TIME
The time: 7 minutes 18 seconds on the Nurburgring-Nordschleife. Power: 620hp Weight: 1370kg (3020 lb) in road trim with all fluids The car: new Porsche 911 GT2 RS World debut: at the Moscow Auto Show on August 25, 2010
The GT2 RS is the fastest and most powerful road-going sports car ever built in the history of Dr Ing hc F Porsche AG, Stuttgart and marks the summit in the 911 range.
With power up by 90hp and weight down by 70kg (154 lb) in comparison with the prior 911 GT2, the new 911 GT2 RS has a weight-to-power ratio of just 2.21 kilos per horsepower, by far the best power/weight ratio in its class.
Obviously, these are ideal ingredients for an ultra-high-performance sports car with supreme agility, combined with blistering performance on the road and, of course, Porsche Intelligent Performance attributes. This manifests itself in fuel consumption and emissions being lower by approximately 5 per cent to 19.8mpg US and 284g/km versus the 911 GT2, despite the extra power and performance.
The six-cylinder boxer engine is boosted by two turbochargers with variable turbine geometry and drives the rear wheels via a six-speed manual gearbox. Sports tires measuring 325/30 ZR19 were developed especially for the 911 GT2 RS to convert this massive power into equally acceleration on the road: 0-62mph in 3.5 seconds, 0-124mph in just 9.8 seconds, and 0-186mph (300km/h) in 28.9 seconds.
Equally supreme stopping power is assured by the PCCB composite ceramic brakes fitted as standard. Appropriate longitudinal and lateral dynamic chassis control is ensured by the sporting RS set-up of the springs, Porsche Adaptive Suspension Management (PASM), anti-roll bars, as well as the engine mounts and PSM Porsche Stability Management.
In its exterior styling, the new 911 GT2 RS stands out from the 911 GT2 through the use of carbon-fiber-reinforced (CFR) components in distinctive matte-black finish. At the front, the wider 911 GT2-style wheels with center-locking are shrouded by flared wheel arches. "GT2 RS" stickers give further differentiation on the doors and engine cover. The upgraded front and rear lip spoilers are also made from CFR. The rear spoiler lip is 10mm higher to ensure aerodynamic precision as well as extra downforce.
From behind the wheel of the 911 GT2 RS, the flair continues. Featuring lightweight seats made from carbon-fiber-reinforced plastic and lightweight interior door panels with door opening straps. The basic interior color is black, contrasting with red alcantara upholstery on the seat center sections and rooflining, as well as segments on the steering wheel, gear shift and e-brake lever.
Limited to just 500 units worldwide, the 911 GT2 RS will be available from September 2010. Further specifications and technical details will be confirmed nearer to launch. Lightweight features developed for the GT2 RS include the use of lighter aluminum transverse arms and diagonal struts in the rear suspension, carbon fiber reinforced front lid and rear spoiler, polycarbonate rear window and side windows, lightweight engine cover, lighter single-mass flywheel, lighter lithium-ion battery. Dynamic enhancements include a new intercooler, metal support bearings complete with ball joints in the front suspension, lightweight door panels, turbo boost increased to 1.6 bar from 1.4 bar, wider front track with wider tires (same dimensions as GT3 RS).
