The GMC Sierra HD has undergone a complete revamp for 2007. Outside it has been redesigned to differentiate it from both its GMC light-duty siblings and its Chevrolet Silverado HD counterpart. Inside, it features two distinct interiors: a well-equipped “pure pickup” style and a more family-oriented, amenity-laden style. Under the hood it offers more powerful gasoline and diesel powertrains backed by GM’s new 5-year/100,000-mile warranty.
