Dealer notes
The 2026 GMC Sierra 1500 Denali Crew Cab — new, with delivery miles only — is on the floor now at Napleton Buick GMC in Crystal Lake, finished in Onyx Black with a Jet Black Forge Perforated Leather interior. This is the diesel Denali: the Duramax 3.0L Turbo-Diesel inline-six paired with the 10-speed automatic and 4WD, dressed at the Denali level with Super Cruise, an adaptive suspension, a power sunroof, and a complete trailering suite already aboard.

Super Cruise is the centerpiece of this Denali's technology story. The hands-free driver assistance system — with lane-change capability — works alongside the multicolor 15-inch diagonal head-up display (Technology Package) and the rear camera mirror to give the driver a full picture of the road ahead and behind.
A 13.4-inch infotainment touchscreen with Google built-in apps, wireless Apple CarPlay and Android Auto, and a Bose 7-speaker premium audio system round out the cab. Up top, a power sunroof opens the interior on clear northern Illinois days.
The Preferred Equipment Group 5SA loads this truck for serious work. The integrated trailer brake controller, in-vehicle trailering system app, trailer side blind zone alert, hitch view, bed view camera, and trailer camera provisions make every hookup deliberate and every haul monitored.
HD Surround Vision and ultrasonic front and rear park assist add confidence in tight quarters. The spray-on bedliner with GMC logo, auto-locking rear differential, 2-speed transfer case, hill descent control, and heavy-duty air filter mean the truck is as capable off-pavement as it is on the highway.
The Denali Premium Suspension with Adaptive Ride Control smooths the transition between both.
Inside, the comfort build is thorough: heated and ventilated front seats, heated second-row outboard seats, wireless charging, a 120-volt interior power outlet, remote vehicle starter, and the chrome wheel-to-wheel assist steps for easy entry. The 20 x 9 multi-dimensional polished aluminum wheels and the Signature Denali Chrome Grille with chrome header give the exterior the presence that matches the trim level.
275/60R20 all-terrain tires are fitted from the factory.
Napleton Buick GMC is at 6305 Northwest Hwy in Crystal Lake — on US-14, convenient from Algonquin, Cary, Lake in the Hills, Carpentersville, and Lakewood, and a short drive from the Metra UP-NW line. We have been family-owned for more than 80 years, and our approach is straightforward: no pressure, no surprises.
If the diesel Denali is on your list, we would be glad to walk you through this one.
