The truck will offer an enhanced TurboMax engine, the available Duramax 3.0-liter Turbo-Diesel, an all-new 5.7-liter V8, and an all-new 6.6-liter V8. Every available engine will use a ten-speed automatic transmission.

GMC has not announced horsepower or torque ratings for the new 5.7-liter and 6.6-liter V8 engines. Those specifications will be released later.
Official towing and payload ratings have not yet been released. Capacity will vary according to the engine, drivetrain, cab, bed, axle ratio, trailering package, and other equipment selected. Once ratings are announced, the Valley GMC team can help shoppers configure a Sierra for towing a boat to Lake Tapps, pulling a camper for a weekend in the Cascades, or hauling equipment around the South Sound.
Yes. GMC has confirmed Super Cruise with trailering capability. Additional trailering technologies, camera views, packages, and trim availability will be detailed closer to launch. These features can make it easier to manage a trailer on busy highways or during longer trips beyond the Puget Sound region.
Super Cruise can provide hands-free driver assistance on compatible roads while towing when the truck is properly equipped and all system conditions are met. Automatic Lane Change and Turn Signal Initiated Lane Change are not available while trailering.
The Sierra 1500 will offer several powertrain and trim choices for drivers who regularly encounter steep grades, wet roads, and changing mountain conditions. Available four-wheel drive and off-road-oriented AT4 and AT4X models can provide added capability when heading up SR 410 toward Crystal Mountain or traveling across the Cascades. Drivers should still use appropriate tires, carry required traction devices, and check current road and weather conditions before winter travel.
The Sierra 1500’s redesigned cabin and available driver-assistance technology should make daily travel through Auburn, Tacoma, Kent, and the greater Seattle area more comfortable. Super Cruise can provide hands-free assistance on compatible roads under proper conditions, while the ten-speed automatic transmission is designed to work with every available engine. Feature availability will depend on the selected trim and equipment.
Yes. The Sierra 1500 Crew Cab offers the passenger space and versatility many families need without giving up truck capability. For example, a Valley GMC Sales Manager switched to a Sierra 1500 as his primary family vehicle after finding that the cabin could comfortably accommodate his three children and that the available lease incentives made the move appealing. Offers change over time, so shoppers should ask Valley GMC about current programs.
Its available four-wheel drive, spacious bed, trailering capability, and selection of off-road trims make the Sierra 1500 a versatile choice for boating, camping, mountain biking, snow sports, and other Pacific Northwest activities. Valley GMC can help match the engine, cab, bed, and trim to how you plan to use your truck.
The announced Denali Ultimate layout includes a 16.3-inch center display, an 11.5-inch passenger screen, a 12.2-inch Driver Information Center, a 15.0-inch Head-Up Display, and an 8.5-inch Rear Camera Mirror. Together, the truck offers more than 60 combined diagonal inches of digital displays.

It is the model most directly aimed at drivers seeking serious off-pavement capability.
The Denali Ultimate receives a standard all-new 6.6-liter V8, more than 60 inches of combined digital displays, a 16-speaker Bose audio system with front head-restraint speakers, forged wood accents, and a standard three-year Super Cruise subscription.
