The 997-series Porsche 911 has hardly been launched, but a race-ready GT3 version of the iconic Züffenhausen sportscar is believed to be at an advanced stage of development already.


reports that a prototype of the new 911 GT3 has been spotted undergoing testing near Porsche’s research and development centre in Weissach. The GT3 is scheduled to be launched in Europe by the middle of next year.


It is believed that the GT3 will not use the old model’s 3,6-litre engine, but an uprated version of the 997 Carrera S’ four-valve-per-cylinder 3,8-litre engine. In standard form, the 3,8-litre unit generates 260 kW, but sources say the GT3’s motor could produce up to 300 kW, with the red line beyond 8 000 r/min, thanks to the addition of lightweight pistons, tweaked VarioCam variable valve timing system and a larger air manifold.


claims the GT3, if fitted with a six-speed manual transmission, could accelerate from zero to 100 km/h in just under 4,5 seconds and achieve a top speed of 290 km/h.


The front end of the GT3 will be characterised by a large airdam with three large ducts to direct cooling air to the radiators. The sportscar’s rear end will have the traditional wing affixed to the engine cover and a reworked valance panel at the bottom of the bumper assembly, housing twin central exhaust outlets.


The GT3 is expected to forego the Porsche Active Suspension Management system for conventional springs and dampers to save weight. Its ride height will be significantly lower than on a standard 911, but although the car will be equipped with standard 18-inch rubber, it will also have rim designs unique to the GT3.
