Porsche 997 Turbo Mk.II
The facelifted version of the 997 Turbo, was unveiled at the 2009 Frankfurt Motor Show. It received a completely new 6-cylinder, 3.8 liter boxer engine delivering 500 HP with revised Borg-Warner variable turbine geometry (VTG) turbos. The 911 Turbo is now only available with a manual gearbox or the optional 7-speed PDK dual-clutch gearbox, which replaces the Tiptronic. With PDK and the also optional sport-chrono package, which includes the availability of a electronically controlled launch-control and an overboost-function for temporary increasing the turbo-pressure, Porsche claims the 911 turbo will go from 0 to 100 km/h (62 mph) in 3.4 seconds and reach a top-speed of 194 mph (312 km/h). However, several tests done by Auto-Magazines and unpartial testers have revealed that the 0-100 km/h acceleration-time is generally as low as 2.9 seconds. The model can now also be ordered with PTV, Porsche Torque Vectoring, which will brake the inner wheel to provide turning-torque through a curve. The looks of the facelifted model was left mostly untouched from the original 997 turbo, but there are subtle changes to the rear lights, now being LED-type, among changes to the front lamps. The rear exhaust outputs are now also "fatter" and the standard 19-inch wheels now have a new design. Thanks to revised dynamics the facelifted 997 can handle 1.3 g forces on a skid-pad according to Porsche. Its believed that the updated 997 Turbo was benchmarked against the Nissan GT-R in response to 3rd party testing between the 997 Turbo and the GT-R.
