Key Features of the 2026 GMC Sierra 1500 Denali Ultimate

Super Cruise® hands-free driver assistance technology

Standard on Denali Ultimate, Super Cruise® helps make every mile more enjoyable by enabling hands-free driving on a growing network of compatible roads. The system uses precision mapping, in-vehicle sensors, and driver attention technology to support confident lane-keeping and following. It is especially helpful on long highway stretches where reducing small corrections lowers fatigue. Super Cruise® complements other assistance systems such as Adaptive Cruise Control and available up to 14 camera views, helping you approach complex driving with greater ease. With an included 3-year OnStar® plan, you get the support and connectivity to make the most of this advanced capability.

6.2L V8 engine with 10-speed automatic transmission

Standard on Denali Ultimate, the 6.2L V8 brings effortless power for passing, merging, and towing. With 420 hp on tap and a 10-speed automatic that keeps the engine in the sweet spot, acceleration feels smooth and immediate. Max available torque reaches up to 495 lb.-ft., translating into confident low-end pull for trailering and steep grades. Selectable Traction Modes — including Sport mode, available Off-Road mode, and Tow/Haul mode — allow you to tailor responses to conditions. Paired with Denali Premium Suspension and Adaptive Ride Control, the chassis continuously reads the road to help deliver a composed, premium ride without dulling the responsiveness drivers expect from a modern V8 truck.

Over 40" diagonal of combined driver-focused digital displays

The Sierra Denali Ultimate elevates in-cabin command with the most combined driver-focused screen real estate in its class — over 40 inches of crisp, configurable displays. The 13.4-inch color touchscreen with Google built-in compatibility provides seamless access to maps, media, and voice-activated functions. In front of the driver, a 12.3-inch Driver Information Center offers Classic, Progressive, Digital, or Clean layouts so you can prioritize the information you want. The available 15-inch multicolor Head-Up Display projects key data onto the windshield to help keep eyes forward. Add the available In-Vehicle Trailering App to create custom trailer profiles and monitor trailer statuses, and you have a truly integrated view of your truck, your load, and your route.

Alpine Umber interior with full-grain leather seating

Luxury is built into every surface. Denali Ultimate’s Alpine Umber interior features full-grain leather seating with plaited contrast stitching and meticulous trim details. The 16-way power front seats with heat, ventilation, and massage help reduce fatigue on long days, while best-in-class Crew Cab front head- and legroom ensure generous personal space. Quiet-tuned materials complement the 12-Speaker Bose Premium Series with Centerpoint surround sound, so your cabin remains a refined retreat even during demanding drives. Authentic materials — including real wood and patterned aluminum accents — reinforce that this is more than a work truck. It is a distinctly premium environment created to enhance daily life, business travel, and family time alike.

GMC MultiPro Tailgate

The world’s first six-function GMC MultiPro Tailgate turns the bed into a flexible workspace. Use the primary gate for traditional loading, drop the inner gate for a step or load stop, or configure it as a standing-height workstation for on-site tasks. The design makes it easier to move gear and set up for the day, while the available CarbonPro® composite bed adds durability and best-in-class short bed cargo volume up to 62.9 cu. ft. For tight trailheads and busy job sites, available up to 14 camera views — including helpful hitch and bed views — can simplify trailer alignment and cargo checks. It is the kind of practical innovation that owners rely on daily.
