Sierra

GMC recently added a hybrid-powered version to its full-size pickup line, though it doesn't include the assist of an electric motor and only saves about a mile per gallon. It employs a flywheel-alternator starter system that's used to de-power its 5.3-liter V-8 engine when the vehicle is stopped to realize about a ten-percent increase in fuel economy. The onboard electric motor can also be used as a portable generator on a job site or at the campground. With an all-encompassing array of configurations, the Sierra, along with its Chevrolet counterpart, the Silverado, can meet a wide range of buyers' needs. A wide range of available powerplants includes the standard 4.3-liter V-6, as well as optional 4.8-liter, 5.3-liter, and 6.0-liter V-8 engines. Heavy Duty models can be fitted with a diesel V-8 or a big-block 8.1-liter gasoline V-8. The 1500 Denali version includes the top V-8 engine and a long list of included amenities. A new-for-2006 VortecMAX performance package is available for light-duty trucks, and includes a 6.0-liter V-8 and enhanced towing package, with a limited-slip differential that's housed in a new, 9.5-inch rear axle, Also, the available Duramax 6.6-liter diesel V-8 is enhanced for 2006 with features that enable smoother, more refined performance with less smoke. A new Allison 1000 six-speed automatic transmission is available for heavy-duty models equipped with the Vortec 8100 V-8 or Duramax Diesel engines. Also for 2006, half-ton extended cab/short box models and new base-model 1500 SL Crew Cab models (with 2WD and 4WD) that carry a lower retail price than previous Crew Cab models are added to the line. What's more, 20-inch chrome wheels become newly available on SLE and SLT 2WD and 4WD Extended Cab and Crew Cab models with the Sierra Special Edition package.
