When it comes to luxury, the editors at the duPont Registry know a thing or two. They measure the finest things in life and discuss their value to their well-heeled readership. Recently, they had a chance to review a GMC Yukon Denali Ultimate to see if GMC’s most luxurious Yukon could meet their high standards.
The 2026 Denali Ultimate is offered in Yukon and Yukon XL. Either way, you are treated to an elevated level of equipment above the Denali trim. Exclusive features include a four-corner Air Ride Adaptive Suspension for a smoother ride. You also get Super Cruise hands-free driving with a three-year OnStar Super Cruise Plan.
The 2026 Yukon Denali Ultimate has upholstered Woodland Mahogany full-grain leather seating surfaces with 16-way power front seats that include a massage feature. For that finishing touch, the 2026 Yukon Denali Ultimate adds a set of 24-inch machined aluminum wheels with After Midnight Metallic Finish.
While the feature list is comprehensive, you can add more to the 2026 Yukon Denali Ultimate with a host of available equipment. For example, there is a second-row executive seating option with heating, ventilation, and massaging features. There is a set of speakers for the head restraints that are part of the Bose Performance Series CenterPoint Surround 22-speaker audio system. There’s also night vision.
Powering the 2026 Yukon Denali Ultimate model is a 420-horsepower 6.2-liter V8 engine or a 3.0-liter six-cylinder turbodiesel with 495 pound-feet of torque. Both engines come standard with 10-speed automatic transmissions and four-wheel drive.
The 16.8-inch diagonal Premium GMC Infotainment System with Google Built-in serves as the technological heart of the 2025 Yukon Denali Ultimate. The duPont Registry said that the new touchscreen “makes reading maps at a glance effortless while offering enough real estate to have multiple apps open simultaneously.”
Editors at the duPont Registry liked the fact that there were actual physical controls in the 2026 Yukon Denali Ultimate, augmenting the large touchscreen. They said that “GMC made the excellent decision to retain physical controls via a row of switches that are almost hidden in plain sight. The result is an interior that feels high-tech without losing its tactility.”
When it came to the standard Super Cruise, the duPont Registry said that “not only does it allow for hands-free driving, but it also does a good job of keeping this family hauler centered in the lane, even if…road markings aren’t always the most clearly defined.”
When it came to taking the 2026 Yukon Denali Ultimate on the road, the duPont Registry said that it was “a pleasant place to be. It remains relatively quiet on the highway. Its front seats are supportive but not firm, and this truck’s air suspension system has no trouble soaking up larger bumps at speed.”
In conclusion, the duPont Registry stated that "the Yukon manages to offer a luxury SUV experience in a package that allows you to fly under the radar.” That is high praise for those of us who want refined luxury.
