Porsche ended a lot of rumors by releasing the first details of the 997 GT2 RS, which will be officially released at the Moscow Auto Show in August. Compared to the 'standard' 997 GT2 it is based on, the limited edition model is considerably lighter and more powerful.
The twin turbocharged flat-six engine is tweaked and now produces a staggering 620 bhp; 90 bhp up from the original figure. All of this power is transferred to the rear wheels only through a six speed manual gearbox. A substantial diet has brought the weight down by 70 kg to 1370 kg (3021 lb) including all fluids. From the outside the GT2 RS can easily distinguished by matt-black finished carbon-fibre parts, wider wheel-arches, unique central-locking alloy wheels and of course "GT2 RS" designations on the doors and rear lid. The interior breaths performance with carbon-fibre seats, lightweight door panels with opening straps and alcantara upholstery. All these changes have raised the top speed to 330 km/h (205 mph) and have enabled the car to accelerate from 0 - 100 km/h in 3.5 seconds.
After its launch in the Russian capital, the GT2 RS will become available in Europe in September and a month later in North America. Production of this very extreme machine is strictly limited to just 500 examples.
