2010 GMC Sierra HD Concept

The GMC Sierra HD was reworked for 2011 with the addition of an all-new chassis and an upgraded 6.6-liter Duramax diesel engine. But while the capable trucks’ guts were given a transplant, the vehicle’s blue-collar exterior and aging interior were left unchanged.

GM have said that we can expect a Sierra HD Concept at the North American International Auto Show in January. The super-sized concept will likely show one possible design direction for the haul-happy pickup, giving it new sheetmetal to accompany its already very capable hardware. To information detail wait until January to find out.!
