Hummer introduced an exciting SUV concept at the Detroit Auto Show 2008 with the Hummer HX.

The Hummer HX features sci-fi styling and is more compact than a Hummer H3.
The slight green glow of the Hummer HX comes from the E85 (85% Ethanol and 15% gasoline) FlexFuel 3.6l SIDI V6 engine.
The roof panels, fender flares, and doors can be removed to dig some serious dirt, while being close to the action.

The design of the Hummer HX is actually from three young designers who just started at GM with a degree from the College for Creative Studies in Detroit.
