The feature that separates this Sierra from other 2026 Denalis is Super Cruise — hands-free adaptive cruise control with hands-free lane change on compatible divided highways, paired with a wrapped Super Cruise steering wheel and a multicolor 15-inch diagonal head-up display (Technology Package). The rear camera mirror replaces the standard mirror with a wide-angle camera view, and the HD Surround Vision with bed view camera and hitch view makes every hookup visible from the cab.
The Denali Premium Suspension with Adaptive Ride Control reads the road continuously and adjusts damping in real time — a meaningful difference on long highway pulls and rough county roads alike.
The Preferred Equipment Group 5SA covers the full trailering suite: an integrated trailer brake controller , trailer side blind zone alert, trailer camera provisions, in-vehicle trailering system app, auxiliary external transmission oil cooler, auto-locking rear differential, and hill descent control. 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 complete the working end.
On the road, a Bose 7-speaker premium sound system , wireless charging, SiriusXM with 360L, Apple CarPlay and Android Auto wireless mirroring, and a 13.4-inch diagonal GMC Infotainment display with Google Built-In keep the cab connected. Comfort features include ventilated and heated front seats , heated second-row outboard seats, a power sliding rear window with defogger, remote vehicle starter, keyless open and push-button start, and a 120-volt interior power outlet.
The 20-by-9-inch multi-dimensional polished aluminum wheels wear 275/60R20 all-terrain tires, and the signature Denali chrome grille with chrome header finishes the exterior.
Napleton Buick GMC is at 6305 Northwest Hwy on US-14 in Crystal Lake — easy to reach from Cary, Algonquin, and Lakewood, and right on the Metra UP-NW corridor. Napleton has been family-owned for more than 80 years, and there is no pressure here, just straightforward answers and time to look the truck over at your own pace.
If you tow regularly and want a diesel Denali that does it with every available assist turned on, this is the one to walk around.
