2026 GMC Sierra 1500 Denali Ultimate Duramax Diesel

This exceptional Pre-Owned 2026 GMC Sierra 1500 Denali Ultimate Crew Cab 4WD delivers an impressive combination of diesel-powered capability, premium craftsmanship, advanced technology, and everyday comfort. Finished in distinctive Coastal Dune over an elegant Alpine Umber full-grain leather interior, this remarkably well-equipped Sierra has traveled just 8,535 miles and carried an original total vehicle price of $85,790.

Duramax Turbo-Diesel Performance

At the heart of this Sierra Denali Ultimate is the highly desirable Duramax 3.0-liter turbo-diesel engine, paired with a refined 10-speed automatic transmission. The Duramax diesel delivers the strong low-rpm torque diesel engines are known for, providing confident acceleration, composed towing performance, and effortless power when hauling, passing, or merging onto the highway.

Its broad torque delivery allows the transmission to remain in higher gears more effectively, helping provide relaxed highway cruising, fewer unnecessary downshifts, and a smooth, controlled driving experience. For owners who regularly travel long distances, tow recreational equipment, or simply appreciate the durability and efficiency of diesel power, the Duramax engine is one of this Sierras most compelling features.

Impressive Diesel Fuel Economy

The diesel powertrain also offers an important efficiency advantage for a luxurious full-size four-wheel-drive pickup. EPA estimates are an impressive 24 MPG combined, 22 MPG city, and 26 MPG highway. This extended driving range can mean fewer fuel stops during long-distance travel without sacrificing the capability, comfort, and commanding road presence expected from a GMC Sierra.

Denali Ultimate Luxury

As GMCs premier Sierra trim, the Denali Ultimate surrounds its occupants with an interior more commonly associated with a premium luxury SUV. The Alpine Umber cabin features full-grain leather seating, open-pore wood detailing, a leather-wrapped steering wheel, and a premium microsuede headliner.

Both front occupants enjoy 16-way power-adjustable massaging seats with heating and ventilation, while rear passengers benefit from heated outboard seating. Dual-zone automatic climate control, driver-seat and mirror memory, a power sunroof, and a power sliding rear window further elevate the cabin experience.

Advanced Technology and Super Cruise

Technology is highlighted by an expansive 13.4-inch GMC infotainment touchscreen, a configurable 12.3-inch digital Driver Information Center, and a 15-inch multicolor Head-Up Display.

Wireless Apple CarPlay, wireless Android Auto, wireless smartphone charging, Google built-in compatibility, and a 12-speaker Bose Premium audio system create a thoroughly connected and refined driving environment.

This Sierra is also equipped with Super Cruise hands-free driving technology, providing added convenience on compatible roads. Additional driver-assistance systems include Front and Rear Park Assist, HD Surround Vision, Enhanced Automatic Emergency Braking, Rear Cross Traffic Braking, Trailer Side Blind Zone Alert, and a Safety Alert Seat.

Capability and Versatility

The Denali Premium Suspension with Adaptive Ride Control helps maintain a composed and controlled ride, while the two-speed Autotrac transfer case and four-wheel-drive system provide added confidence when road or weather conditions become challenging.

Practical truck features include the versatile GMC MultiPro Tailgate, factory spray-on bedliner, LED cargo-area lighting, integrated trailer brake controller, trailer camera provisions, front recovery hooks, and the Trailering Package.
