2026 GMC Yukon Denali Ultimate

The chassis and powertrain make the case first. Magnetic Ride Control continuously reads the road and adjusts the dampers in real time, so the Yukon absorbs Illinois highway expansion joints without float or crash.

Active Response 4WD goes further: it torques individual wheels through corners, not just between axles. Under the hood the 6.2L EcoTec3 V8 breathes through a dual exhaust system and routes power through a 10-speed automatic.

The 2-speed electronic Autotrac active transfer case with hill descent control handles the moments when pavement ends. Rolling it all forward are 24 x 9.5 selective machined and painted wheels — the sticker identifies the finish as After Midnight Metallic — wrapped in 285/40R24 all-season tires.

Inside, the Preferred Equipment Group 5SB defines this truck's character. Both front seats heat, ventilate, and massage independently; each has a 4-way power lumbar adjuster and a 2-way power upper shoulder bolster.

The driver's seat adds a memory position. The steering column tilts and telescopes under power, and the 4-spoke leather-wrapped wheel holds the controls. Super Cruise — the hands-off highway driving system with automatic lane change — is the headline technology, paired with a 15-inch multi-color head-up display that keeps navigation and speed at eye level.

The 16.8-inch diagonal GMC Infotainment touchscreen anchors connectivity: wireless Apple CarPlay, Android Auto, and a built-in Wi-Fi hotspot. Audio is an 18-speaker Bose surround system with Centerpoint processing.

Second-row passengers get power-release bucket seats; the third row is managed from the second row or the AutoSense hands-free power liftgate. An 8-inch diagonal rear touchscreen controls climate for rows two and three.

Power-retractable assist steps deploy automatically when a door opens.

Driver assistance spans adaptive cruise control, blind spot monitoring with cross-traffic alert, rear parking sensors, a 360-degree camera system, trailer assist, and the fog lights and advanced headlight control that come standard on this trim. The sport pedal cover kit, bright door sill plates, and Vader bodyside moldings finish the exterior details.

The dual-pane panoramic power sunroof opens the cabin when the weather cooperates.

Napleton Buick GMC is at 6305 Northwest Hwy on US-14 in Crystal Lake, right on the Metra UP-NW line and convenient to Fox River Grove, Algonquin, Cary, Carpentersville, and Lakewood. We have been family-owned for more than 80 years, and there is no pressure here — just a straightforward process and the people who know this vehicle well.

If the Denali Ultimate is on your list, this one is on the lot and ready to look at.
