2026 GMC Yukon XL AT4

The 2026 Yukon XL is GMC's largest SUV, a three-row full-size that prioritizes passenger space and towing capability for big families. It goes head-to-head with the Chevrolet Suburban, Ford Expedition Max, and Jeep Wagoneer L in the extended-length SUV segment. The Yukon XL feels substantial on the road, with confident straight-line stability and a commanding view over traffic. The ride is generally composed for a vehicle this size, though the independent rear suspension helps smooth out rough pavement. Inside, the cabin offers generous space for eight, with a cavernous cargo area behind the third row and upscale materials on higher trims. The AT4 sits between the Elevation and Denali trims, adding off-road hardware like the two-speed transfer case and air suspension without pushing all the way into luxury territory. The 5.3L V8 makes 355 horsepower and pairs with a ten-speed automatic, giving you enough grunt for daily driving and towing, while the four-wheel drive helps keep you moving on dirt or snow. The air ride adaptive suspension and Magnetic Ride Control come standard on the AT4, which helps smooth out rough trails without ruining the highway ride.
