GMC SIERRA
From job-ready Work Truck models to the unique combination of performance and luxury that is the Sierra Denali, the GMC Sierra lineup is one of the broadest in the industry. Powerful Vortec-based powertrains, backed by fuel-saving six-speed automatic transmissions, help Sierra models deliver among the industry's best fuel economy and performance - all with responsive ride and handling traits, and an exceptionally quiet driving experience. Sierra 1500 is available in several trim packages, including Work Truck, SL (crew cab only), SLE and SLT, along with 2WD and 4WD configurations. Three cab styles - regular, extended and crew cab - and three cargo box lengths - 5 foot 8 inches, 6 foot 6 inches and 8 foot - are offered. All models except the Work Truck model come with a distinctive chrome hood molding.
