2026 GMC Sierra 1500

The 2026 GMC Sierra 1500 Denali Ultimate Crew Cab 4WD combines premium luxury, advanced technology and serious truck capability in GMC’s flagship Sierra trim. Finished in Onyx Black with an exclusive Alpine Umber interior, this Sierra is powered by the 3.0L Duramax Turbo-Diesel paired with a 10-speed automatic transmission and four-wheel drive.

The Duramax diesel delivers the strong, confident performance expected from a premium full-size truck, while a 2-speed Autotrac transfer case, automatic locking rear differential and Denali Premium Suspension with Adaptive Ride Control help provide capability without sacrificing ride quality. StabiliTrak with Trailer Sway Control and Hill Start Assist adds further confidence when towing or travelling on challenging roads.

Trailering capability is supported by the factory Trailering Package, integrated trailer brake controller, In-Vehicle Trailering App, Trailer Side Blind Zone Alert and HD Surround Vision with Bed View. A 120-volt power outlet is provided in both the cargo bed and instrument panel, adding useful functionality at the jobsite, campsite or cottage.

The Denali Ultimate cabin is designed around premium comfort with full-grain leather seating in Alpine Umber. Both front occupants receive heated and ventilated 16-way power seats with lumbar adjustment and massage functionality, while the second-row outboard seats are also heated. A heated leather-wrapped steering wheel, power tilt and telescoping steering column and driver seat and mirror memory further enhance everyday comfort.

Technology is highlighted by Super Cruise, with up to three years of OnStar One with Super Cruise included. The Sierra also features a 13.4-inch GMC Premium Infotainment touchscreen with Google built-in and navigation capability, wireless Apple CarPlay and Android Auto, a 12.3-inch digital Driver Information Centre, 15-inch Head-Up Display and Rear Camera Mirror.

A 12-speaker Bose premium audio system delivers an upscale listening experience inside the cabin, while the dealer-installed MultiPro Audio System by Kicker brings additional audio capability to the tailgate area. A power sunroof adds natural light and an open-air feel to the premium interior.

Outside, the Onyx Black finish is complemented by the Black Badging Package with black GMC emblems and badging. GMC MultiPro power steps provide convenient cab and bed access, while the MultiPro Tailgate adds versatile loading and work functionality. A factory spray-on bedliner, LED cargo-area lighting and moulded splash guards add protection and practicality.
