This truck combines serious towing and hauling capability with the refined appointments you expect from the Denali nameplate. The Duramax diesel engine delivers the torque needed for demanding work, while the 10-speed transmission provides smooth power delivery across varied driving conditions. The cabin reflects Denali's premium positioning with genuine wood accents, leather-appointed seating, and a comprehensive technology suite that keeps you connected and informed on every journey.

Weather protection and visibility are prioritized throughout the truck. Rain-sensing wipers, automatic high-beam headlights, front fog lights, and power-sliding rear windows with defogger ensure you maintain control in challenging conditions. Heated and ventilated front seats, along with heated rear outboard seats, add comfort during cold weather drives. The winterized features, including an engine block heater and heavy-duty battery, prepare the truck for demanding climates.

The technology integration enhances both convenience and safety. The in-vehicle trailering system app provides real-time information about your trailer, while hitch guidance with hitch view simplifies maneuvering. Automatic emergency braking, forward collision alert, and rear cross-traffic alert work together to help prevent accidents. The surround vision system with multiple camera angles gives you complete awareness around the truck, whether navigating tight spaces or backing into a trailer.

The off-road suspension and traction control systems adapt to changing conditions, while electronic stability control maintains composure during aggressive maneuvers.
