Frankfurt motor show 2007 - Porsche

Another month, another 911. Porsche, based less than two hours down the autobahn from Frankfurt, chose its homeland to reveal the GT2, the most extreme version of its timeless rear-engined coupe.

Like the Ferrari F430 Scuderia, it's an exercise in upping power and shaving off weight to create a car for ultimate enthusiasts who'll want to enjoy their cars on race tracks as well as public roads.

The turbocharged 3.6-litre flat-six engine gains another 50bhp and now peaks at 523bhp, while there's also more pull - 501lb ft from just 2200rpm.

Porsche quotes a 0-60mph time of 3.6 seconds and a top speed of 204mph.

Mind you, you'll need to know how and where to let rip because the 911 Turbo's four-wheel-drive system has been ditched as a contribution towards a 10% overall weight saving - power is transmitted to the rear wheels only.

Carbon-ceramic brakes are standard, though, and the rear silencer and exhaust tailpipes are made from titanium, saving more weight.

All of this hikes up the price to £131,070 – some £33,000 more than a 911 Turbo and £37,000 more than a GT3 RS.

The GT2 will be available in the UK in November.
