2026 GMC Sierra 1500 Denali

The Technology Package brings two standout features: a rear camera mirror that replaces the conventional rearview with a wide-angle camera feed, and a multicolor 15-inch diagonal head-up display that projects speed and navigation data onto the windshield. Super Cruise adds hands-free highway driving and lane-change capability on mapped roads.

The 13.4-inch GMC Infotainment System runs Google built-in navigation and voice assistance, connects wirelessly to Apple CarPlay and Android Auto, and streams through the premium Bose 7-speaker sound system. A SiriusXM with 360L trial subscription, wireless charging pad, Wi-Fi hotspot capability, and multiple USB-A and USB-C ports round out the connectivity picture.

The Preferred Equipment Group 5SA loads the Denali with the trailering suite that makes this truck genuinely useful on a job site or at a boat launch: an integrated trailer brake controller, Trailering Package, in-vehicle trailering system app, trailer side blind zone alert, hitch view, bed view camera, HD Surround Vision, and trailer camera provisions are all included. The spray-on bedliner with GMC logo, LED cargo area lighting, chrome wheel-to-wheel assist steps, chrome recovery hooks, and heavy-duty air filter add working capability.

The 20 x 9 multi-dimensional polished aluminum wheels wear 275/60R20 all-terrain blackwall tires. The 2-speed AutoTrac transfer case with off-road mode and hill descent control handle low-traction conditions; the auto-locking rear differential and Denali Premium Suspension with Adaptive Ride Control keep the ride composed whether the bed is loaded or empty.

Inside, the Denali delivers ventilated front seats, heated front and second-row outboard seats, a power-raking and telescoping steering column, remote vehicle starter, keyless open and push-button start, rain-sensing wipers, power sliding rear window with rear defogger, deep-tinted glass, a 120-volt interior power outlet, floor-mounted center console, and universal home remote. GMC Pro Safety adds forward collision mitigation, rear cross traffic braking, rear pedestrian detection, ultrasonic front and rear park assist, and lane keep assist.

The active dual exhaust is sport-mode enabled. The power sunroof and perimeter lighting finish the exterior presentation alongside the chrome Signature Denali grille.

Napleton Buick GMC is at 6305 Northwest Hwy on US-14 in Crystal Lake, convenient to Cary, Algonquin, Lake in the Hills, and Huntley, and right on the Metra UP-NW line. Napleton is a family-owned group with more than 80 years in the business — no-pressure, straightforward from the first conversation.

If you've been looking for a Denali with the full technology and trailering build, this truck is worth a close look.
