The EcoTec3 5.3L V8 engine paired with a 10-speed automatic transmission delivers the muscle needed for confident towing and hauling, while the 4WD system ensures capable handling across varied terrain. With an EPA rating of 16 city and 20 highway MPG, this powertrain balances performance with reasonable fuel efficiency for a truck of this caliber.

The AT4 Premium Package elevates your driving experience with a dual-pane panoramic sunroof that floods the cabin with natural light, creating an open and airy atmosphere. The power-retractable assist steps make entry and exit effortless, while perimeter lighting adds both safety and style during evening arrivals.

Inside, the cabin feels refined and purposeful. Heated and ventilated front seats with 12-way power adjustment ensure your comfort on long drives, while a heated steering wheel adds a premium touch during cold mornings. The rear passengers enjoy heated outboard seats and a power-folding third row, making this vehicle genuinely accommodating for extended families or groups.

Technology seamlessly integrates into daily driving through the 15-inch head-up display, which keeps essential information within your line of sight. The Bose 9-speaker audio system paired with SiriusXM 360L connectivity, Apple CarPlay, and Android Auto gives you control over your entertainment and navigation. A rear media system keeps rear passengers engaged, while the hands-free power liftgate adds convenience when your hands are full.

Safety and capability work in concert throughout this SUV. Hill Descent Control, Lane Keep Assist, Rear Cross Traffic Alert, and Automatic Emergency Braking provide modern protection, while the HD surround vision camera helps you navigate parking and tight spaces with confidence.

This 2021 Yukon AT4 is ready to take you forward. We invite you to experience its commanding presence and thoughtful engineering firsthand at our showroom.
