2026 GMC Sierra 1500 Denali

The cabin is where the Denali separates itself. Super Cruise — the hands-free driver-assistance system with lane change capability — pairs with the Super Cruise wrapped steering wheel and a multicolor 15-inch diagonal head-up display so the road information stays in your sightline, not on the dash.

A 13.4-inch diagonal GMC infotainment system with Google built-in apps handles navigation and voice assistance; Apple CarPlay and Android Auto mirror wirelessly. The Bose Premium 7-speaker sound system, ventilated and heated front seats, heated second-row outboard seats, wireless charging, a 120-volt interior outlet, and a power sunroof round out the inside story.

The Preferred Equipment Group 5SA arms this Denali for real-world work without asking you to sacrifice comfort. The Trailering Package includes an integrated trailer brake controller, trailer side blind zone alert, hitch view, bed view camera, HD Surround Vision, trailer camera provisions, and the In-Vehicle Trailering System app — the full picture every time you back up to a hitch.

Supporting hardware includes an auxiliary external transmission oil cooler, auto-locking rear differential, heavy-duty air filter, and hill descent control. Outside, 20-by-9-inch multi-dimensional polished aluminum wheels wear 275/60R20 all-terrain tires, and the chrome header with Signature Denali chrome grille gives the exterior its rank.

Chrome wheel-to-wheel assist steps, a spray-on bedliner with GMC logo, chrome recovery hooks, and LED cargo area lighting take care of the bed and the approach. The active dual exhaust is sport-mode enabled and makes the 6.2L sound the part.

The Technology Package adds the rear camera mirror — the full-width display that replaces your standard rearview with a camera-fed image — alongside that multicolor head-up display. Forward collision mitigation, rear pedestrian detection, rear cross traffic braking, ultrasonic front and rear park assist, and GMC Pro Safety round out the driver-assistance suite.

Remote vehicle starter, keyless open and start, rain-sensing wipers, perimeter lighting, universal home remote, and a Wi-Fi hotspot-capable connection handle the everyday details. OnStar services-capable and SiriusXM with 360L trial subscription are also included.

Napleton Buick GMC is at 6305 Northwest Hwy in Crystal Lake — on US-14, a straightforward drive for shoppers from McHenry, Woodstock, and Barrington. We're a family-owned group with more than 80 years in the business, and we run a no-pressure process because the truck should sell itself.

If the Denali is what you've been building in the configurator, this one is already here — bring your trailer dimensions and take it on a proper test drive.
