One of the world’s most hardcore roadsters has been given a shot in the arm to produce this – the GTK concept.

Danish tuner Kleemann has taken a standard Mercedes-Benz SLK 55 AMG and ramped up the power to a monstrous 540bhp.

And this power means a 0-62mph time of just 3.7 seconds – faster than a Ferrari F430 – and a top speed just shy of 190mph.

Kleemann has bolted on a supercharger to the SLK’s 5.4-litre V8 engine – which in standard guise churns out 360bhp – and has fitted massive 380mm vented brakes, 20-inch specially-designed Kleemann alloy wheels, a Kleemann limited slip differential, and retains Mercedes’ 7G-Tronic seven speed auto box.

And this drivetrain is housed inside a stunning concept car body – with only the doors, roof and windows remaining the same as the AMG production version.

Kleemann employed car designer Christian Brandt to head up the ‘top secret’ GTK design project, and the concept car features radical new styling including carbon fibre body panels along with other ‘high performance Kleemann products’.

The GTK concept is a showcase for future design and performance ideas that may come across in future Kleemann-built Mercedes-Benz cars.
