Porsche's tweaking of the 911 continues unabated - here's the next-generation GT2, spied during tests at the Nordschleife.
The new machine could be one of the fastest 911s ever. It's said to use a tweaked 997 Turbo motor, producing up to 520bhp, 47bhp more than the current Turbo. And since it's rear-wheel drive only and features 'GT' weight-saving techniques, it could be more than 100kg lighter than the regular model.
The motorsport-influenced GT2 will only be available with a six-speed manual gearbox. But unlike the first version, it's not an homologation special - it's a road car only.
