A full-size pickup variant of the Chevy Silverado.

Overview Information

Designed for serious hauling, the Sierra is the workhorse pickup in the GMC lineup. The 1500 series model can be equipped with engines ranging from a 4.3L V-6 to a 6.0L V-8, all mated to a 4-speed automatic or 5-speed manual. Heavy-duty 2500 and 3500 series models offer 6.0L and 8.1L V-8 options, or a 6.6L Duramax® V-8 diesel. Transmission choices include a 4-speed and 6-speed automatics, or 5-speed and 6-speed manuals. A new Sierra 1500 hybrid model (with a 14 kW electric motor/generator) offers 10% increased fuel economy vs. the standard 1500 equipped with a 5.3L V-8. As an added benefit, the hybrid Sierra can be used as a portable electric power source to run 120V appliances or tools. Sierra trucks are available in 2WD or 4WD drivetrains. The luxurious Sierra Denali offers full-time AWD. As expected, these pickups can be equipped for serious towing capabilities, and have a rated GVWR of up to 12,000 lbs.
