Detroit 2011: GMC Sierra All Terrain HD Concept Dwarfs The Competition
By Brandon Turkus
January 11, 2011
While we have already previewed GMC’s Sierra All Terrain HD Concept, seeing it in the flesh is a different deal entirely. This thing is big, and the two-foot tall stand that GMC mounted it on certainly made it look even bigger.
We snapped a fair few pictures of this monster, which we have posted in the accompanying gallery. And if this isn’t enough, check out the preview we did of the HD Concept a few weeks back (right here).
