Dealer notes
The 2026 GMC Yukon AT4 Ultimate is a new, five-door three-row 4WD SUV at Napleton Buick GMC in Crystal Lake — finished in Onyx Black with an Obsidian Rush with Red Accents full-grain leather interior. It has delivery miles only, meaning it has never been titled or registered.
Where the Denali Ultimate leans toward luxury touring, the AT4 Ultimate layers genuine trail-ready hardware underneath that same premium interior, making it the right Yukon for the driver who wants both trail capability and first-class comfort on the same weekend.

The Preferred Equipment Group 4SG builds the off-road foundation: all-terrain 275/60R20 tires on 20 x 9 machined and painted wheels, a front skid plate, red horizontal-mounted recovery hooks, hill descent control, front high-approach angle fascia, and the Premium Capability Package with Active Response 4WD and Magnetic Ride Control suspension. The 2-speed electronic Autotrac active transfer case handles the transition from pavement to trail, and the power-retractable assist steps make entry and exit easy regardless of terrain.
A heavy-duty air filter rounds out the outdoor hardware.
Inside, the Preferred Equipment Group brings the long-haul comfort story: perforated heated and ventilated front bucket seats with power massage for both driver and front passenger, 4-way power lumbar adjustment on both sides, power-release second-row bucket seats, and a dual-pane panoramic power sunroof. The driver gets a power tilt-and-telescopic steering column and a sport pedal cover kit.
An 8-inch rear touchscreen handles climate for the back rows. Sound comes from the Bose 18-speaker surround system with Centerpoint. The 15-inch multi-color head-up display keeps eyes up on speed and navigation.
Super Cruise hands-off cruise control with lane change — part of the Advanced Technology Package — handles the long Interstate stretches, and Apple CarPlay and Android Auto connect wirelessly. Bright front and rear door sill plates and black roof-mounted luggage rack side rails add the finishing details, and the Floor Liner Package covers every row with all-weather floor liners and includes an all-weather cargo mat.
Napleton Buick GMC is at 6305 Northwest Hwy in Crystal Lake, on US-14 near the Metra UP-NW line and a short drive from Lake in the Hills, Huntley, and McHenry. The Napleton family has been in the automotive business for over 80 years, and the process here is low-pressure — bring your questions and we will work through them.
If your weekends run from pavement to two-track and back, this AT4 Ultimate is worth a look.
