GM Introduces GMC Yukon 'AT4 Ultimate' to Expand Range of High-End SUVs

DETROIT — General Motors is expanding its high-end GMC Yukon lineup to include a new “AT4 Ultimate” model as part of updates to the full-size SUV for the 2025 model year.

The new model will slot between the luxury “Denali” and “Denali Ultimate” models. The automaker declined to comment on pricing for the new AT4 Ultimate, but Denali models currently start at about $77,300 and just under $100,000, respectively. The current AT4 model starts at $73,500.

The Denali models, now in their 25th year, have become a money-making machine for GMC. In recent years, the automaker added the “Ultimate” and “AT4” models, featuring off-road styling and some unique parts, to further expand the range and pricing of the high-end models.

“We're raising the bar for what our customers expect from GMC's flagship model and the addition of the AT4 Ultimate trim fuses ruggedness and capability with craftsmanship and refinement,” Duncan Aldred, GMC global vice president, said in a statement.

AT4 sales account for about 17% of total Yukon sales, compared to Denali models, which account for more than 50% of large SUV sales.

New AT4 Ultimate models include a front skid plate and 20-inch wheels with all-terrain tires; adaptive air suspension at all four corners that can lift the vehicle up to 2 inches; and other features.

Higher-trim models have helped GMC achieve an average transaction price of about $80,000 for the Yukon, according to GM.

In addition to the AT4 Ultimate, the 2025 Yukon will receive updates including new styling, larger screens, second-row executive seating and increased availability of a 3.0-liter diesel engine to help improve range and fuel economy compared to gas-powered models.

The 2025 GMC Yukon will be produced at GM's Arlington, Texas, assembly plant and is expected to be available in late 2024.
