This full-size SUV combines versatility with refined engineering. The EcoTec3 5.3L V8 engine paired with a 10-Speed Automatic transmission delivers the power you need for towing and hauling, while achieving 15 city and 20 highway MPG. The available 4WD system ensures confident handling across varied terrain and weather conditions.

Inside, the Yukon AT4 prioritizes your comfort and connectivity. The heated and ventilated front seats adjust to your preferences, while the heated steering wheel welcomes you on cold mornings. The 15-inch diagonal multi-color head-up display keeps important information in your line of sight, and Apple CarPlay and Android Auto integration keeps you seamlessly connected to your devices.

Safety remains paramount in this design. Forward Collision Alert, Automatic Emergency Braking with Front Pedestrian Braking, and Lane Keep Assist work together to help protect you and your passengers. The HD Surround Vision system and rear cross traffic alert provide visibility when you need it most, while the Safety Alert Seat offers additional awareness during potential hazards.

The spacious three-row layout accommodates up to eight passengers comfortably, with power-folding third-row seats that maximize cargo flexibility. The powered rear liftgate and power-release second-row bucket seats make accessing the interior effortless. Premium leather seating surfaces, heated rear outboard seats, and an overhead console with ambient controls elevate the cabin experience.

The AT4 Premium Package distinguishes this model with a panoramic power sunroof that floods the cabin with natural light, along with power-retractable assist steps featuring perimeter lighting both practical and visually distinctive. The included technology package, premium floor liners throughout all rows, and an all-weather cargo mat demonstrate GMC's commitment to protecting your investment.
