NEW FOR 2011:
- Wind noise reduction enhancements
- OnStar 9.0
- Exterior colour: Grey Green Metallic added
For 2011, changes to the GMC Sierra are minor. There are enhancements to reduce wind noise and OnStar is upgraded to 9.0.
An all-new heavy-duty (2500 and 3500) model is offered for 2011 and is covered under a separate section.
Also sold as the Chevrolet Silverado, and available as a hybrid model, the Sierra is offered in Regular, Extended and Crew Cab models, with short box (5-foot-8), standard box (6-foot-6) and long box (8-foot), and in two- or four-wheel drive.
Engine choices in the 1500 are a 4.3-litre V6 or 4.8-litre V8 with four-speed automatic, and 5.3-litre V8, 6.0-litre V8 and the Denali’s 6.2-litre V8, all with six-speed automatic. The Hybrid uses a 6.0-litre V8 with Active Fuel Management and Auto Stop mode, regenerative braking, and a two-mode continuous electric ratio hybrid transmission, for a fuel economy improvement of up to 32 per cent when compared to a conventional Sierra. The system can launch the truck on battery power and run solely on electricity at speeds of up to 48 km/h, and keeps the engine in its fuel-saving Active Fuel Management mode for longer periods of time.
Features on the WT (Work Truck) include 17-inch steel wheels, air conditioning, manual black mirrors, variable intermittent wipers, overhead console, rubberized vinyl floor covering, standard instrument panel with upper and lower glove boxes, tire pressure monitoring system, driver information centre, tilt steering wheel, 40/20/40 front bench seat with cloth or vinyl trim, centre fold-down armrest, AM/FM stereo, automatic headlamps, and OnStar.
