2026 GMC Sierra 1500 Denali Ultimate

At the heart of the 2026 GMC Sierra 1500 Denali Ultimate sits a standard 6.2-liter V8 engine paired with a 10-speed automatic transmission, delivering the kind of confident, responsive power that serious drivers demand. For those who prefer diesel capability, an available Duramax 3.0-liter Turbo-Diesel engine is also on the table. The standard TurboMax engine produces 310 horsepower and best-in-class standard torque of 430 pound-feet, with available max towing of up to 9,400 pounds. When properly equipped with a Double Cab 2WD configuration and the available Duramax engine, the Sierra 1500 can tow up to 13,300 pounds — making it ready for demanding hauls and heavy-duty weekend adventures alike.

Step inside the Denali Ultimate and you're immediately surrounded by exceptional craftsmanship. Full-grain leather seats with plaited contrast stitching make a striking first impression, while 16-way power heated and ventilated front seats with a massage feature ensure every ride is thoroughly comfortable. A 12-speaker Bose Premium Series audio system with Centerpoint surround sound fills the cabin with rich, immersive sound. The Sierra 1500 also offers best-in-class standard Crew Cab front head- and legroom, ensuring that passengers have plenty of space to stretch out. Real wood trim, patterned aluminum accents, and Forge perforated-leather seating surfaces complete the premium atmosphere from every angle.

The 2026 Sierra 1500 Denali Ultimate equips drivers with an impressive and intuitive suite of technology. Standard Super Cruise hands-free driver assistance technology comes paired with a three-year OnStar One plan, giving drivers the freedom to go hands-free on a growing network of compatible roads. The cabin features over 40 inches diagonal of combined driver-focused digital displays, keeping critical information vivid and accessible at all times. An available ProGrade Trailering System streamlines the hitching and towing process, while up to 14 available camera views help drivers navigate tight spaces and manage a trailer with total confidence. A signature Denali Vader Chrome grille and exclusive 7-spoke Ultra-Bright 22-inch machined aluminum wheels with Bright Chrome accents complete the bold exterior statement.

GMC Pro Safety technology gives the 2026 Sierra 1500 Denali Ultimate a comprehensive foundation of driver assistance and collision-avoidance features designed to help keep you aware and protected. Available features include Front and Rear Park Assist, HD Surround Vision, and Hill Descent Control — an antilock braking feature engineered to provide a smooth, controlled descent on steep grades. For off-road ventures, Terrain Mode is available on 4WD models equipped with a single-speed transfer case, offering finer control at low speeds on rough surfaces. These technologies work together to give you added confidence, whether you're navigating city streets or venturing off the beaten path.
