Nuclear power

German tuning house Geiger gives the Corvette Z06 a mighty 890bhp. Be afraid. Be very afraid…

Some cars are delicate, subtle instruments. Surgeons' scalpels, if you will. Some cars are 12-pound lump hammers. Now, which category do you think the Geiger Corvette falls into?

Ignore, if you can, that retina-melting lime green paintjob (which, we have to confess, we actually rather like). Focus instead on what's lurking under that louvred hood.

Geiger - the German pioneers responsible for the Martini-themed Hummer and the torquetastic Ford F-650 pickup - has taken the Corvette Z06's shabby 500bhp 7.0-litre V8 and bored it out to a far heathlier 7.6 litres. Oh, and added a pair of fat turbos for good measure.

The result? 890bhp and 694lb ft of torque. And the sort of acceleration more commonly associated with ground-to-air missiles.

Wisely, Geiger has beefed up the Vette's drivertrain to cope with all that power. There's now a heavy-duty, twin-disc clutch and a carbon fibre driveshaft. We're happy to hear that it gets adjustable coilover springs and bigger brakes, too.

And no true tuning job would be complete with a set of a giant wheels and a big body kit. Those big holes in the hood are fuctional, by the way: according to the Geiger press release, 'they guard against thermal indispositions of the turbo engine.'

Beware those thermal indispositions...

Now watch Clarkson thrash the Z06 back in 2006: 

Now share it...
