The powertrain is the story. The Duramax 3.0L turbo-diesel I6 sends power through a 10-speed automatic, and the Preferred Equipment Group 5SA adds the hardware that makes this a serious work truck: an integrated trailer brake controller, trailer side blind zone alert, hitch view, bed view camera, trailer camera provisions, the in-vehicle trailering system app, and an auxiliary external transmission oil cooler.
The auto-locking rear differential and hill descent control give the 4WD system real utility off the pavement, and the heavy-duty air filter and 220-amp alternator reflect a truck built for sustained work. The spray-on bed liner with GMC logo and LED cargo area lighting round out the bed.
Inside, the Denali Premium Suspension with Adaptive Ride Control is paired with 20-inch multi-dimensional polished aluminum wheels on 275/60R20 all-terrain tires — refined on the highway, capable when the road ends. The Technology Package adds a multicolor 15-inch diagonal head-up display and a rear camera mirror.
Super Cruise hands-free highway driving with lane change is fitted, alongside forward collision mitigation, rear pedestrian detection, rear cross traffic braking, trailer side blind zone alert, and HD Surround Vision with ultrasonic front and rear park assist. The 13.4-inch GMC Infotainment System runs Google built-in with navigation and voice assistance, wireless Apple CarPlay and Android Auto, and is backed by a Bose 7-speaker audio system.
The cabin adds wireless charging, a 120-volt interior power outlet, heated and ventilated front seats, heated second-row outboard seats, remote start, and a power sunroof.
Napleton Buick GMC is at 6305 Northwest Hwy on US-14 in Crystal Lake — on the Metra UP-NW line and convenient to Woodstock, Barrington, Fox River Grove, and Carpentersville. Family-owned for more than 80 years, we work without pressure. When this Denali arrives, ask us to have it ready for a thorough walk-around — the diesel alone is worth the drive.
