Specialist tuning firm creates unique SLK-based supercar
29 October 2007

Kleemann is best known as a specialist Mercedes tuning company, but it's now gone a step further and created the Kleemann GTK concept.Designed by Christian Brandt, the newly revealed GTK openly takes styling cues from Mercedes, and uses the SLK55 AMG's 5.5-litre V8 engine and chassis, but that's where the similarity ends.The GTK is fitted with a Kleemann supercharger that boosts power to 533bhp and torque to 516lb ft; a huge increase over the standard SLK55's 355bhp and 376lb ft.As you'd expect, the resulting statistics are impressive. It's claimed that the Kleemann GTK will hit 62mph in 3.7sec and is limited to 186mph. The GTK also gets a Kleemann limited slip differential, uprated brakes and the Mercedes 7-speed automatic gearbox.No prices have been released, but Kleemann does state that the GTK will not go into mass production. A handful of examples will be sold, but the GTK is more of a showcase for Kleemann's abilities, and a hint at the design direction planned for future Kleemann-tuned Mercedes. This is probably a good thing. Considering the SLK55 barely handled its power at our 2007 best driver's car test, an extra 178bhp is not what Merc's tyre-shredding baby roadster needs.
