2026 GMC Yukon XL Denali

Comfort and technology inside: The Preferred Equipment Group 5SA brings perforated heated and ventilated driver and front passenger seats, four-way power lumbar for both front seating positions, power-release second-row bucket seats, and a 15-inch diagonal multi-color head-up display. The Advanced Technology Package adds Super Cruise hands-free driver assistance, an auto-dimming rear camera mirror, and the rear seat media system — so the back row has its own entertainment.

A 16.8-inch diagonal GMC Infotainment display anchors the front console, with wireless Apple CarPlay and Android Auto, navigation, a mobile hotspot, and wireless charging. Power tilt and telescopic steering column, an AutoSense hands-free power liftgate, and power-retractable assist steps with perimeter lighting round out the daily-use details.

Suspension, ride, and driving assistance: Magnetic Ride Control suspension works with the air ride adaptive system to read the road continuously and adjust damping in real time — a meaningful upgrade on a vehicle this size. Super Cruise allows hands-free driving on compatible divided highways.

The 15-inch head-up display keeps speed and navigation visible without looking down. Driver Attention Assist, forward collision mitigation, pedestrian impact prevention, blind zone steering assist, lane keep assist, and cross-traffic collision avoidance are all on board.

The 6.2L V8 paired with the 10-speed automatic delivers the power delivery expected at this trim level.

Trailering, when you need it: The Max Trailering Package adds hill descent control, an integrated trailer brake controller, the 2-speed electronic Autotrac active transfer case, Hitch View, Smart Trailer Integration Indicator, blind zone steering assist with trailering, and an extra-capacity cooling system. The Enhanced Trailering Technology Package layers on trailering assist guidelines, trailer camera provisions, and a wired auxiliary trailer camera.

The Denali Reserve Package contributes the dual-pane panoramic power sunroof and the power-retractable assist steps. The Advanced Security Package includes a theft-deterrent alarm, vehicle inclination sensor, interior movement sensor, and glass breakage sensor.

All-weather floor liners for the first and second rows and a set of four wheel locks come from the factory as well.

This Yukon XL is on the lot at 6305 Northwest Hwy in Crystal Lake — on US-14, a short drive from Algonquin, Lake in the Hills, and Huntley. Napleton Buick GMC has been part of the Napleton family for over 80 years; the process here is straightforward and unhurried.

If the full-size SUV that earns its keep on a road trip is what you have in mind, this one is worth a walk-around.
