Porsche has already hit hard with the updates for everything up to the GT3 road-racer and the all-wheel drive 911 Turbo, but the GT2 promises a new take on its performance business.
Its twin-turbo, 3.6 litre engine is expected to get punch beyond the current 370 kiloWatts and a significant body tweak with a giant rear wing, as well as the much-needed paddle shifters first seen in the latest Turbo.
Some of the updating work - particularly the rear wing - are obvious on the Carparazzi pictures of the GT2 testing at the Nurburgring in Germany. Porsche has not revealed any lap times and is unlikely to trumpet too much now that Ferrari has claimed the outright road-car mark (at 6 mins 58.16 secs) with its FXX version of the Enzo supercar.
The hotter new GT2 is expected to preview at the Paris Motor Show in October, signalling the start of sales and the end of the latest 997- series of the 911. The 998 story begins in 2011 and production-ready prototypes of the upcoming 911 have already been seen in both Germany and Scandinavia undergoing testing ahead of the launch of the next new Carrera 2.
