For 2009, the Sierra lineup enhances its segment-best fuel economy with a new six-speed automatic that is paired with V-8 engines (except the 4.8L). Additionally, the 6.2L engine previously exclusive to the Sierra Denali is offered on SLT crew cab models; it is also more powerful than last year's model and E85-capable. Other new features and content changes give customer more choices that support both safety and convenience.
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.
The unique Sierra Denali, a truck that fuses performance and unmatched luxury, also returns for 2009. It is a distinct model, with features that elevate its performance and design, such as a 6.2L all-aluminum V-8 engine with E85 FlexFuel capability, variable valve timing and a six-speed automatic transmission.
New SLT standard equipment for 2009 includes a six-speed automatic transmission, including heavy-duty cooling; automatic locking rear differential; heavy-duty trailering package; 18-inch chrome-clad aluminum wheels; remote vehicle starting system and Bluetooth connectivity for phones.

It is outfitted with special shocks, unique four-bar grille, exclusive leather-appointed interior, 18-inch chrome wheels and more (see Sierra All-Terrain section below).
