2003 Chevrolet Cheyenne

While it was understood that the Chevy Cheyenne would not be going into production itself, the bold truck featured design cues that GM planned for near- future product. That included the wheels-to-the-corner layout, innovative two-position tailgate and side access panels. The Cheyenne came equipped with a 6.0-liter version of the Vortec V-8 that pumped out 500 horsepower and 580 lb.-ft of torque.
