2026 GMC Yukon XL AT4 Ultimate

Experience the right-hand drive 2026 GMC Yukon XL AT4 Ultimate Diesel in Summit White with a Jet Black/Walnut interior only from Autogroup International, blending full-size luxury with off-road confidence. Powered by GMC’s refined 3.0-litre Duramax® Turbo Diesel inline-six, it delivers exceptional torque, quiet efficiency, and long-distance capability – perfectly suited to both adventure and everyday refinement.

The AT4 Ultimate adds premium off-road engineering, including an Active Response 4WD System, two-speed transfer case, Magnetic Ride Control, Air Ride Adaptive Suspension, and underbody skid plates for all-terrain durability. Bold 20-inch machined aluminum wheels wrapped in all-terrain tyres, red tow hooks, and exclusive AT4 styling details complete the commanding presence of this flagship SUV.

Inside, the GMC Yukon XL AT4 Ultimate surrounds you with technology and craftsmanship. Premium full-grain leather upholstery, heated and ventilated first- and second-row seats, heated steering wheel, and power-folding third-row seats ensure every passenger travels in comfort. The 15-inch GMC Premium Infotainment touchscreen with Google built-in, 12-inch digital driver display, Bose® Performance Series audio, and head-up display deliver cutting-edge connectivity and entertainment.

With this Yukon XL you get real-world comfort and practicality: second row captain’s seats for an easy walk-through and individual seating, plus 4.6 cm more third row legroom so adults actually fit. You also gain a boot that holds six full size suitcases behind the third row, which the short wheelbase cannot match.

Safety and confidence come standard with HD Surround Vision, Rear Pedestrian Alert, Automatic Emergency Braking, and Lane Keep Assist with Lane Departure Warning.
