The 2017 GMC Sierra 3500HDs are offered in 4x2 and 4x4 models with either a single rear wheel (SRW) or a double rear wheel configuration if extra payload and/or towing requirements are needed. The bold new exterior houses a choice of gas or bi-fuel (gasoline and CNG) 6.0-liter V8 or Duramax 6.6-liter diesel engines, a fully updated cabin with available IntelliLink connectivity and other features designed for the most discerning truck owners. GMC designers evolved the Sierra 3500HD's familiar shape while adding distinctive details like standard projector headlamps, available LED signature accent lighting and detailed new grilles. All Sierra models have chrome grille surrounds and premium black wheel arch moldings, and different trim levels feature chrome belt moldings, mirror caps and door handles, as well as unique wheel designs and grille details. A new double-cab model, which features forward-hinged rear doors, replaces the previous extended cab, and allows easier access to the back seat, especially in tight parking spaces. The rear doors on crew-cab models are larger, and combined with revised seats, create more rear legroom and enable easier entry and exit for back seat passengers. The body and chassis are designed to improve ride and handling, comfort and capability. Four distinct trims are offered and these include the Base, SLE, the SLT on double or crew cabs and the Denali which are available on crew cabs only. Regular cabs have 8-foot box lengths, while double cabs are available with either 6-foot, 6-inch or 8-foot boxes, and crew cab customers can choose between 6-foot, 5-inch or 8-foot boxes. The standard engine on all Sierra HDs is a 360 horsepower and 380 lb-ft of torque 6.0L Vortec gasoline V8, matched to a six-speed automatic transmission. A bi-fuel version of the 6.0-liter will run on either gasoline or compressed natural gas is available. The re-engineered optional Duramax 6.6-liter diesel, with 445 horsepower and 910 lb-ft of torque, is mated to the Allison 1000 6-speed automatic transmission. Standard Trailer Sway Control keeps both the truck and trailer heading in the same direction, automatically. All models receive a standard automatic locking rear differential. The CornerStep bumper, combined with handholds built into the new box rail protectors, makes it easier to access the box. IntelliLink, standard on all models except the base work truck, provides easy-to-use connectivity for the job site or the family vacation, with natural voice recognition and enough ports and power outlets to support multiple devices. For owners whose work or recreation takes them off road, the Z71 Package includes Rancho shocks, a skid plate and Hill Descent Control.
