This model comes finished in Onyx Black with an interior trimmed in Obsidian Rush leather featuring red accents for a bold and upscale aesthetic.

Powering the Yukon AT4 Ultimate is a 6.2L EcoTec3 V8 engine paired with a 10-speed automatic transmission and a capable 4WD system. With the Premium Capability Package and Active Response 4WD, the Yukon is designed for confident driving on varied terrain. The Air Ride Adaptive Suspension system further enhances comfort and handling, while features like Hill Descent Control, an electronic limited-slip differential (eLSD), and a front high-approach angle fascia support off-road capability. Trailering is also a key strength, with the Max Trailering Package, integrated trailer brake controller, blind zone steering assist with trailering, and Hitch View all included. The Extra Capacity Cooling System and heavy-duty air filter help keep systems running optimally under load.

Inside, the Yukon AT4 Ultimate is equipped with advanced technology and premium materials throughout. It features heated and ventilated front seats with massage functionality and 4-way lumbar support, along with power release second-row bucket seats and a power-tilt and telescoping steering column. A 16.8-inch diagonal premium GMC infotainment system anchors the center stack and supports navigation through GMC Connected Navigation. Rear seat passengers benefit from an 8-inch rear touchscreen climate control interface and a Rear Seat Media System. Apple CarPlay and Android Auto compatibility, along with SiriusXM with 360L, provide extensive connectivity and entertainment options. Audio is delivered through an 18-speaker Bose Surround system with CenterPoint technology.

A 15-inch diagonal multi-color head-up display and a digital rear camera mirror help keep key driving information in view. Super Cruise, GMs hands-free driver assistance system, is also included, expanding convenience and safety on compatible highways. The Advanced Technology Package and Advanced Security Package add features such as Driver Attention Assist, Smart Trailer Integration Indicator, a Glass Breakage Sensor, and a Theft-Deterrent Alarm System with interior motion and inclination sensors. Rain-sensing wipers, automatic climate control, and power-retractable assist steps add to daily ease of use.

Exterior touches include body-color door handles, red horizontal-mounted recovery hooks, a black roof-mounted luggage rack, and distinctive 20-inch machined and painted wheels. The dual-pane panoramic sunroof and AutoSense hands-free power liftgate contribute to both functionality and comfort. Wheel locks, sport pedal covers, and bright front and rear door sill plates add subtle but thoughtful finishing details.

The Yukon AT4 Ultimate also includes three years of OnStar Digital Services and Safety Services, providing added peace of mind with access to emergency assistance, vehicle diagnostics, and more.
