Second is the RENNtech Rally Racer. It was inspired by cars that tackle the Pike's Peak hill climb in the unlimited class. This GLK is fitted with RENNtech's first hybrid powertrain to improve acceleration off the line and exiting corners.
Third, a GLK by Boulevard Customs. This shop decided to turn their vehicle into a street machine, giving it a widebody kit hanging over massive 26-in. wheels. Inside the Urban Whip, passengers are treated to a custom interior and a hugely powerful sound system.
Last, the Legendary Motorcars Company has gone the opposite way with their GLK, instead creating an off-roader called the Four Corners Rock Crawler. The vehicle features a unique winching system for bringing skateboarders and wakeboarders up to speed so that they can grind down the vehicle's special side rails.
