BMw M3 news - G-Unit: 600bhp BMW M3 - 2010

Most people celebrate a win with a bottle of bubbly, some thumbs, a night on the town and a dodgy kebab - not a pair of 600bhp street-legal modified BMW M3s.

In honour of BMW's win at the 2010 Nurburgring 24hr endurance race, German tuner G-Power decided 400bhp was nowhere near enough mentalism, and promptly injected precisely insane amounts of mentalist-ness into the M3 to create the M3 GT2 S and M3 Tornado CS.

Both cars get a supercharger kit - the same found on the Alpina B6 GT3 - and a titanium exhaust system boosting power to an almighty 600bhp and 428lb ft of torque. That's quite a bit of mentalism, you'll agree.

The 0-62mph sprint takes a smidge over four seconds and both cars will top out at 199mph.

G-Power has stripped the lard from the GT2 S version by replacing the front and rear bumpers and all four wings with carbon fibre versions, together with racing seats and lightweight alloys. This diet sheds the M3 of an incredible 150kg. Time to make skinny friends...

The German tuner built this monster M3 because apparently customers wanting a Porsche 911 GT3 RS-shaped car can't find one in the BMW garage. They obviously haven't tried looking in the ‘Porsche' shop, but whatever.

The GT2 S costs £120,000 and the GT3 RS weighs in at £105,000. Choose your weapon, gentlemen...
