Official Photo and Details for 620hp Porsche 911 GT2 RS

This is the new 911 GT2 RS, successor to the 997-based GT2. All you really need to know is this: 620 horsepower from 3.6 twin-turbocharged liters, a 'Ring time of 7:18, and "improved fuel economy" (by 5%). For less important information, read on.

It's lost 154 lbs or 70kg, gained 90 horsepower, and it doesn't like you. This fiend comes with a standard 6-Speed manual gearbox, Porsche's fancy ceramic brakes, "unique anti-roll bars", new tires measuring 245/35 ZR 19 at the front and 325/30 ZR 19 at the rear that were specifically developed for this car,and a whole lot of other fancy suspension doo-dads. You'll also notice an abundance of carbon fiber and matte black paint.

Inside, carbon fiber 2-piece buckets are standard, as are those nylon straps replacing the door handles.

The official speed numbers are 0 to 60 (96km/h) in 3.4 (no doubt due to traction issues) and a 205 mph or 330km/h top-end barrier.

The GT2 RS is being limited to a scant 500 units coming in at $245,000 a pop (cheaper than most estimates), and will be debuting at the Moscow Auto Show on August 25th 2010.
