    Notes from the dealer

    2026 GMC YUKON AT4 ULTIMATE 4WD 6.2L V8 SUPER CRUISE MASSAGE SEATS AIR RIDE SUMMIT WHITE LANCASTER PA

    This 2026 GMC Yukon AT4 Ultimate 4WD is powered by the 6.2L EcoTec3 V8 paired with a 10-speed automatic transmission. Finished in Summit White, this is about as loaded as a Yukon gets, combining Super Cruise, massage seats, Air Ride Adaptive Suspension, panoramic moonroof, Max Trailering Package, and serious AT4 off-road hardware.

    The AT4 Ultimate is what happens when you want Denali-level luxury but don't want a Yukon that looks afraid of dirt.

    Under the hood is the 6.2L V8, producing 420 horsepower and 460 lb-ft of torque. It's smooth and quiet around town, but there's still a big naturally aspirated V8 waiting when you need to merge, pass, or pull a trailer.

    The capability underneath this Yukon is what really separates it. The Premium Capability Package with Active Response 4WD includes an electronic limited-slip differential, while Air Ride Adaptive Suspension and Magnetic Ride Control work together to deliver a more controlled ride on pavement while adding useful capability when conditions get rough. You also get Hill Descent Control, a high-approach front fascia, heavy-duty air filter, and those signature red recovery hooks.

    Inside is where the Ultimate name starts making sense.

    Both front passengers get heated, ventilated, and power-massaging seats. There's a huge dual-pane panoramic moonroof, 18-speaker Bose Surround system, 15-inch Head-Up Display, Rear Camera Mirror, rear-seat entertainment, second-row bucket seats, and power-retractable running boards.

    Then there's Super Cruise, giving you hands-free driver assistance on compatible roads. For an SUV built to swallow highway miles and family road trips, that's a feature you'll appreciate quickly.

    This Yukon can work too. The Max Trailering Package adds an integrated trailer brake controller, Hitch View, extra-capacity cooling, trailer integration technology, and Blind Zone Steering Assist with Trailering.

    And the odometer is sitting an impressive 4,252 miles below the market average.

    If you're searching for a 2026 GMC Yukon AT4 Ultimate 6.2L V8 near Lancaster, this is the one that gives you almost everything in one package. Super Cruise, massage seats, Air Ride, panoramic roof, rear entertainment, serious towing equipment, and real off-road capability without giving up the 6.2 V8.
