While this General Motors division positions its trucks as 'professional grade,' the similar Chevrolet Silverado ranks as the high-volume member of the duo. Sierras are available in half-ton 1500, three-quarter-ton 2500HD and one-ton 3500 forms. No regular 2500 series exists, but a 1500HD is offered. Whereas the higher-rated models provide an increased level of hauling and towing capabilities, the 1500 series offers editions that aren't available in the others, like the Sierra Denali luxury pickup. For 2006, GMC's Sierra Hybrid expands to nationwide availability it previously was offered only in select markets. Though its electrical motor does not actually propel the vehicle, GMC still classifies it as a hybrid. The Sierra Denali is a luxury pickup with a 345-horsepower, 6.0-liter V-8 permanent all-wheel drive and a specially tuned suspension. Chevrolet doesn't offer an equivalent to the Sierra Denali, and GMC offers no equivalent to the high-performance Chevrolet Silverado SS. Offered as a Crew Cab rather than an extended-cab truck, the Denali features leather seats and can be fitted with a sunroof and 20-inch wheels. For 2006, several new packages, trims and configurations are available — most notably a new base-model 1500 SL Crew Cab at a lower price than the 2005 base SLE Crew Cab. Also, the optional 6.6-liter turbo-diesel V-8 on Sierra 2500HD and 3500 models gets more power, and a new six-speed-automatic transmission replaces the previous five-speed in models equipped with this engine. Exterior Light-duty Sierra styling is similar to the heavy-duty models. The Terra4 concept truck inspired the Sierra 1500's front end. Sierras differ from Silverados mainly in the front, which is dominated by a bolder grille and a prominent red GMC badge. Regular-cab, extended-cab and Crew Cab models are offered. Crew Cab trucks have four conventional front-hinged doors. Extended-cab trucks have two front doors and a pair of narrow back doors that open toward the rear and can't be opened unless the front doors are open. The 1500HD is available only in Crew Cab form. Denalis have chrome running boards and a unique front fascia. Interior Regular-cab models seat either three occupants on a bench or two in twin buckets, while extended-cab pickups have a rear bench seat and can carry five or six people. Models with bucket seats have a standard center console that flows up into the instrument panel. Optional uplevel mirrors have a power-folding feature for parking in narrow spaces. For 2006, available camper mirrors offer manually extendable surfaces for increased visibility when towing a camper or trailer. XM Satellite Radio is available. Denali and SLT models have a six-CD changer. Crew Cab trucks can be equipped with a DVD-based entertainment system. Under the Hood The engine choices for the Sierra 1500 include one V-6 and a selection of V-8s. A 195-hp, 4.3-liter V-6 a 285-hp, 4.8-liter V-8 and a 295-hp, 5.3-liter V-8 are offered. A version of the 5.3-liter V-8 can run on gasoline or E85, which is 85 percent ethanol and 15 percent gasoline. An aluminum variant of the 5.3-liter V-8 produces 310 hp. The Denali is fitted with a 345-hp, 6.0-liter V-8, while the 1500HD is powered by a 300-hp, 6.0-liter V-8. Available transmissions include a five-speed manual and a four-speed automatic. Three four-wheel-drive systems are available. Insta-Trac is an on-demand system with a floor-mounted transfer case it is available on base models.
