Key Features of the 2026 GMC Yukon XL

3.0L Duramax Turbo-Diesel I6

The available 3.0L Duramax Turbo-Diesel inline-six pairs robust low-end torque with a quiet, composed character that suits the Yukon XL’s mission. It is the powertrain to choose when you want strong pull at low rpm for merging with a trailer, easing up a grade, or navigating stop-and-go traffic with a full cabin. The engine’s broad torque band complements the standard 10-speed automatic, helping the transmission keep revs low and shifts smooth. GMC engineers tuned the Duramax for refinement, and you feel it at idle and highway speeds alike. When your plans include a boat ramp, a cargo trailer, or an extended family road trip with loaded luggage, the diesel’s confident thrust makes the big SUV feel unflappable.

16.8-Inch Diagonal Center Touchscreen with Google Built-In

Every Yukon XL features a vertically oriented 16.8-inch touchscreen that anchors the cabin with crisp graphics and intuitive menus. Google Built-in provides native access to Google Maps, Google Assistant, and Google Play, while wireless Apple CarPlay and Android Auto keep your preferred ecosystem front and center. A built-in Wi-Fi hotspot supports multiple devices on family trips, and an available rear-seat entertainment system adds dedicated screens to keep passengers engaged. The interface is quick to respond, with climate, camera, and towing views logically arranged so you can keep your attention on the road. The result feels integrated — fewer taps to do more, and the kind of clarity that gives you confidence at a glance.

Denali Details and 16-Way Front Seats with Massage

Denali raises the bar with thoughtful materials and long-haul comfort. Open-pore wood trim with laser-etched topographical patterns, satin-finish metals, and available 16-way power front seats with heating, ventilation, and massage turn everyday drives into a restorative routine. Craftsmanship is evident in the way surfaces meet and in the quieted cabin that lets the Bose audio systems shine — with 10, 18, or an available 22 speakers strategically placed for immersive sound. Selecting Denali Ultimate pushes the premium experience even further, approaching flagship-luxury territory while retaining the everyday usability and durability that define GMC SUVs.

Advanced Trailering Camera Views and Alerts

GMC’s trailering toolkit puts practical technology to work. Transparent Trailer View uses clever camera stitching to virtually “see through” a compatible trailer, revealing obstacles directly behind it. The system’s Jack-Knife Alert can warn when your steering angle risks an acute trailer articulation, while multiple hitch and surround views aid alignment, backing, and tight-space maneuvers. Combined with the Yukon XL’s stable, long-wheelbase stance and strong powertrain options, these features help you tow with the assurance that you have the visibility and information you need when it matters most.

AT4 Off-Road Enhancements

If your routes take you beyond pavement, the AT4 adds confidence-building hardware. A two-speed transfer case supports low-range control, while 20-inch wheels wrapped in all-terrain tires and underbody skid plates increase protection and bite. An available air suspension can raise ground clearance by up to approximately two inches to help clear obstacles, and the chassis’ independent rear suspension supports both ride composure and stability on uneven surfaces. The AT4’s capability is not just about occasional trails — it also pays dividends in deep snow, muddy boat ramps, and rutted jobsite access roads.
