GM reveals GMC Yukon 'AT4 Ultimate' to expand reach, profits of high-end SUVs

General Motors will introduce a new “AT4 Ultimate” model to its GMC Yukon lineup for the 2025 model year. This addition aims to expand the reach and pricing of the high-end GMC Yukon models, particularly the Denali line. The “AT4 Ultimate” will occupy a position between the existing “Denali” and “Denali Ultimate” models. By introducing appealing features such as a front skid plate, 20-inch wheels with all-terrain tires, and four-corner adaptive air suspension that can raise the vehicle up to 2 inches, General Motors hopes to further boost sales and maintain an average transaction price of around $80,000 for the Yukon.
