2026 GMC Sierra 1500 Denali

The technology story sets this Denali apart from every other Sierra on the lot. Super Cruise — the hands-free highway driving system with lane-change capability — pairs with a Multicolor 15-inch Diagonal Head-Up Display and a Rear Camera Mirror (replacing the traditional mirror with a wide-angle live feed) for a driving experience that feels a full generation ahead.

The 13.4-inch diagonal GMC Infotainment System runs Google built-in navigation and voice assistance, wireless Apple CarPlay and Android Auto, and feeds a Premium Bose 7-Speaker Sound System. SiriusXM with 360L, a Wi-Fi hotspot, wireless charging, and six USB ports — including two USB-C rear charge-only ports — cover every passenger.

The Denali's capability hardware is equally complete. The Trailering Package includes an integrated trailer brake controller, HD Surround Vision, Hitch View, Bed View Camera, Trailer Side Blind Zone Alert, Trailer Camera Provisions, and the In-Vehicle Trailering System App — everything needed to hook up and go with confidence.

Supporting that is the 6.2L EcoTec3 V8 backed by an Auxiliary External Transmission Oil Cooler, Auto-Locking Rear Differential, and Heavy-Duty Air Filter. On all-terrain 275/60R20 tires mounted on 20 x 9 Multi-Dimensional Polished Aluminum wheels, the Denali Premium Suspension with Adaptive Ride Control smooths the road whether the bed is empty or loaded.

Chrome Recovery Hooks and a Spray-On Pickup Bedliner with GMC Logo finish the working end; Chrome Wheel-to-Wheel Assist Steps and the Signature Denali Chrome Grille dress the exterior.

Inside, the Preferred Equipment Group 5SA brings heated and ventilated front bucket seats, heated second-row outboard seats, a Remote Vehicle Starter System, Keyless Open and Start with Push Button Start, a Power Sliding Rear Window with Rear Defogger, Rain-Sensing Wipers, Perimeter Lighting, a 120-Volt Interior Power Outlet, Universal Home Remote, and a Floor-Mounted Center Console. GMC Pro Safety adds forward collision mitigation, rear cross traffic braking, rear pedestrian detection, Ultrasonic Front and Rear Park Assist, and Lane Keep Assist — plus the Active Exhaust with dual sport-mode enabled outlets and a power sunroof round out the build.

Napleton Buick GMC is at 6305 Northwest Hwy in Crystal Lake — on US-14 near the Metra UP-NW line, convenient for shoppers coming from Huntley, McHenry, Woodstock, and Barrington. We have been family-owned for more than 80 years, and we work toward a straightforward, no-pressure process on every sale.

If the Denali is the truck you have been configuring in your head, this one is on the lot and ready to look at up close.
