With more than 100-year heritage of building professional grade vehicles, the 2007 GMC Sierra lineup elevates industry standards higher with segment-best V-8 power and fuel efficiency, along with agile ride and handling and the quietest interior of any full-size truck. The ’07 Sierra models – including the unique Sierra Denali – deliver the light-duty segment’s highest-rated towing capacity of 10,500 pounds and offer a maximum payload capacity of 2,160 pounds. Sierra is offered in light-duty and heavy-duty models, available in several trim packages, including SLE1, SLE2 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. Buyers have a selection of 7-different engines that range from the 195 horsepower, 4.3-liter V-6 to the 6.2-liter V-8 rated at 400 horses. The engines are backed by proven Hydra-Matic electronically controlled automatic transmissions, including a 4-speed automatic and a new 6-speed with the 6.2 V-8.
