The 2011
GMC Sierra 1500 shares its basic design and engineering with the
Chevrolet Silverado 1500, but dresses in more image-conscious trim. Unfortunately, the Sierra 1500 doesn't change from the 2010 model. This means that its bold
GMC-badged grille will be the main visual distinction from the Silverado. The vehicle's overall look is handsome and confident. The 2011 will again offer a three-cab roster consisting of a two-door regular cab, an extended cab, and a crew cab.
