General Motors' heavy-duty truck twins - the GMC Sierra HD and Chevrolet Silverado HD - were 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. With Ford and Ram updating the look and feel of their heavy duty pickups over the past year, we're thinking GM won't stand idly by forever, and we may have a peak at the next Sierra sooner than you think.

Our friends over at PickupTrucks.com are reporting that sources within 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. Will the concept look production-ready, or will it be a pie in the sky rendering on wheels? We'll have to wait until January to find out.
