2026 GMC Sierra 3500HD Denali Ultimate

The 2026 GMC Sierra 1500 Denali Ultimate represents the most advanced and luxurious pickup in GMC history. Designed for the discerning driver who accepts nothing less than the best, the Ultimate trim takes the legendary Denali nameplate and elevates it with exclusive Vader Chrome accents, a world-class interior, and standard high-performance hardware.

This Denali is dressed in a bright Glacier White Tri-Coat Exterior Paint with a stunning Alpine Umber Interior.

Mechanically, this Denali is outfitted with the best of the best. Under the hood is the legendary 6.6L Duramax V8 TurboDiesel producing a staggering 470 horsepower and an absolutely crushing 975 lb-ft of torque. It's paired to the renowned Allison Heavy-Duty 10-Speed Automatic Transmission with an AutoTrac 2-Speed Transfer Case, and an Eaton Auto-Locking Rear Differential with 3.42 Gears giving you all the equipment and all the power to tackle any weather condition, conquer any terrain, and basically pull a house right off it's foundation.

A convenient Remote Start System pre-conditions the engine and cabin, bringing them up to operating temperature. Great for those cold winter mornings. This Sierra also comes equipped with an engine block heater.

Keyless Entry welcomes you to Heated & Ventilated Full-Grain Leather Bucket Seats with Position Memory, Genuine Wood-Panel Interior Inserts, a booming BOSE 12-Speaker Premium Audio System with Apple CarPlay & Android Auto capabilities, and an inspiring Powered Moonroof.
