Mercedes-Benz has twisted 4 of its new GLK compact SUVs over to after market tuners to craft one-off custom cars.

The RENNtech Rally Racer has been stimulated by the Pikes Peak hill climb rally cars, but has an extra trick: a hybrid power train, with the electric motor adding up further backing for quicker acceleration off the line.

Merc tuner Brabus has constructed the Widestar, with wide-track body kit, extensive wheel arches, new bumpers, special Brabus wheels and customized inside.

Boulevard Customs has severed off the roof of its GLK, equipped a wide-body kit and 26″ wheels, made over the interior and matched a bespoke sound system. The outcome, called Urban Whip, is rather significant of the customized Suzuki Vitaras accepted in the UK in the 1980s.

Legendary Motor Cars, meanwhile, has created the Four Corners Rock Crawler, which has beefed-up 4WD plus a winch to tow skateboarders – who can also ride down the car’s side rails.

The GLK 350, with 3.5-liter V6 petrol engine, will be for sale in North America in January 2009. The GLK will also be for sale in Europe, but not the UK.

The custom cars will be displayed at the SEMA show in Las Vegas next week.
