2011 GMC Sierra All Terrain HD Concept

This is new photos of GMC Sierra All Terrain HD Concept different with the previous post. The new photos includes the first photos of the design study's interior that has been spruced up with higher quality and more luxurious materials than the standard Sierra, upon which it is based.

GM plans to debut at next week's North American International Auto Show, GMC says the concept model is an exploration of heavy-duty truck capability combined with greater off-road versatility. Even if the Sierra All Terrain HD Concept doesn't make it as is onto the road, chances are that it will inspire a future production version.
