RENNtech's Pikes Peak-inspired hybrid GLK

Of all the trucks that have proliferated into the Mercedes-Benz line-up, the GLK isn't exactly the most aggressive. But according to the latest reports, Mercedes is lining up an array of aftermarket tuners at the SEMA show to infuse what appears to be more than a little testosterone into the compact sport-ute.

First up to bat is RENNtech, the Florida-based company responsible, among other things, for the bringing the McLaren SLR 722 to America and actually getting it to produce 722 horsepower. RENNtech has taken inspiration from the Pikes Peak challenge – one of the most iconic and power-craven hill-climb events in the world – to create this hardcore GLK. Little is known in the way of details, but the vehicle is said to feature RENNtech's first performance hybrid drivetrain.

Brabus, Blvd Customs and Legendary Motorcars are also said to be preparing modified GLKs for SEMA, although Mercedes has not yet confirmed its participation in the show.
