The Terradyne pickup truck was first displayed to the public at the 2000 North American International Auto Show. It featured a 6.6 L Duramax diesel V8 engine and GMC's Quadrasteer four-wheel steering, which later became a production option on full-size pickups for the 2002 model year.[1] All four doors were designed to part in the middle, sliding torward the front and rear (similarly to minivan doors) rather than swinging outwards.[2] It also featured an extended cab pushed forward to create more room for passengers, and a cargo bed that can be expanded from six feet to eight by means of an extending tailgate and is equipped with 110 and 220 volt power outlets, fed by an on-board engine-driven 5000 watt generator.[3]

The Terracross was an all-wheel-drive concept SUV unveiled in 2001.[4] It followed a design language similar to that of the preceding Terradyne concept and shared similar sliding rear doors.[5]

Notable features included a three-panel sliding glass roof, and a reconfigurable mid-gate and window that can create a rear cargo compartment separate from the passenger area.[4] This idea was later used on vehicles like the GMC Envoy XUV and Chevrolet Avalanche. Similar to the rear doors of a minivan, the rear doors open by sliding toward the rear of the vehicle parallel to its sides. There are no B-pillars, and the front passenger seat can swivel to face the rear seating area.[4] The interior of the vehicle is surrounded by translucent green lighting, and it includes sophisticated electronics such as a laptop computer integrated into the dashboard and an OnStar system.[5]

The Granite was a compact crossover SUV introduced at the 2010 North American International Auto Show in Detroit.[8][9] If produced, the Granite would have been GMC's smallest crossover SUV.

It was powered by a 1.4 L EcoTec turbocharged I4 that produced 138 hp (103 kW) and 148 lb⋅ft (201 N⋅m) of torque, matched to a six-speed automatic transmission.[9]
