The GM portfolio has a new luxury truck in its lineup, the 2011 GMC Acadia Denali. The tag applies to luxury versions of its Yukon SUV and Sierra pickup with distinct styling add-ons, standard luxury gear like leather trim and DVD navigation, and in those trucks and SUVs, an all-wheel-drive system that takes the place of a more basic four-wheel drivetrain. In the Acadia, the Denali trim can be applied to seven- or eight-passenger versions No drivetrain changes are made from the standard 3.6-liter V-6 and six-speed automatic, though the front-driver will be offered with optional all-wheel drive. GMC says the basic version will earn a 24-mpg highway mileage rating from the EPA. Cosmetic distinctions from the standard Acadia include a new grille, front and rear bumpers, high-intensity discharge headlamps, and 20-inch wheels. Inside, Denali drivers will get tri-zone climate control, DVD navigation with real-time traffic, satellite radio, USB connectivity, Bluetooth connectivity, a power driver seat, remote start, leather upholstery, and heated and ventilated front seats.
