GMC Sierra All-Terrain HD Concept

Due to be released at the Detroit International Auto Show from GM: The GMC All-Terrain HD concept. You may be familiar with the half ton Sierra All-Terrain (different wheels, grille, interior than a standard Sierra) but the HD goes a little more off the map…. Powered by the 6.6L Duramax diesel, the truck also has an extra 3 inches of ground clearance, is 4 inches wider, and rides on 20-inch wheels wrapped in 35-inch offroad tires with Fox off-road shocks (same as used on the Ford Raptor.)

Inside, the concept comes with Denali-spec interior and satin metal finishes – much like it’s half ton counterpart, but also has the upcoming next generation 80 gB hard drive that we’ll be seeing across the full GM line in the next few years. Being a concept there are no plans to actually produce the truck… yet… but if it were to be produced you would likely see it come from a third party firm as opposed to rolling off the GM production line looking like that.

Will be excited to see the concept at the Detroit show, and maybe find a few more details about possible production of the truck, but for now enjoy the pictures.
