The 2026 Yukon XL Elevation is designed to make the "carpool shuffle" feel like a luxury getaway. With Tri-Zone Climate Control, everyone stays at their ideal temperature, while the heated seats and steering wheel keep NH winters at bay. Need to load up for a weekend at the lake? The power-release second-row seats make it easier than ever to expand your cargo space. Under the hood, the Elevation delivers the confidence of a standard 5.3L V8, available in both 2WD and 4WD. For those looking for the cutting edge of convenience, look for models equipped with Super Cruise—the industry's first true hands-free driver assistance technology—making those long road trips easier than ever.

The AT4 takes everything you love about the Elevation trim and adds a rugged, premium edge. It's the perfect balance of "go-anywhere" capability and "stay-all-day" comfort. Inside the cabin, you're treated to ventilated seating and the latest tech, while the exterior makes a bold statement with its 20-inch machined wheels and off-road styling. Experience the future of driving with available Super Cruise hands-free technology—the perfect companion for the long road back from a weekend adventure. Pair that with the available Air Ride Adaptive Suspension, and you have a full-size SUV that can raise itself for obstacles and lower itself for easy entry.

The difference between the 2026 GMC Yukon XL AT4 Ultimate and the standard AT4 comes down to one thing: the AT4 Ultimate is a fully loaded, more luxurious version of the already-capable AT4. Stay ahead of the curve with standard Super Cruise hands-free driver assistance technology and available Night Vision, which uses thermal imaging to help you spot hazards in the dark. While the technology is cutting-edge, the capability remains legendary. With standard 4WD, a high-output 6.2L V8, and the ability to raise the vehicle's height via the Air Ride Adaptive Suspension, you are prepared for any New England weather or terrain. All this is wrapped in a sophisticated exterior featuring unique AT4 Ultimate badging and premium accents.

Experience a ride that adapts to you. With standard Magnetic Ride Control, the Denali smooths out every imperfection in the road, ensuring your passengers enjoy a serene, first-class experience from Rochester to the coast.

For even more confidence and comfort, available features include Night Vision and second-row heated and ventilated executive seating with massage and integrated Bose head-restraint speakers—making the Denali Ultimate the ultimate choice for drivers who want unmatched luxury in a full-size SUV.
