GM has unveiled new photos with its Detroit Motor Show bound GMC Sierra All Terrain HD Concept. Unlike the previous images, this new set of photos are also offering a view of the interior which as you can notice, features higher quality materials than the standard 2011 Sierra HD.

The GMC Sierra All Terrain HD is equipped with a 6.6-litre Duramax turbodiesel V8 plant which outputs 397 horsepower and 765 lb.-ft. of torque, and a six-speed Allison 100 transmission is responsible for putting power to the ground.

In terms of dimension the GMC Sierra All Terrain HD is wider and sits higher above the ground than the standard Sierra, and if for more details regarding this heavy duty truck we'll have to wait until the official unveiling at the Detroit Motor Show.

On January 10th we also might find out if the GMC Sierra All Terrain HD will make it into production or not.
