Everything You Need to Know on the All-New 2025 GMC Yukon AT4 Ultimate Trim

GMC raised the bar again in the premium SUV segment by introducing the first-ever AT4 Ultimate trim on the 2025 Yukon. This new flagship variant celebrates the fifth anniversary of GMC's AT4 sub-brand by combining exceptional off-road capability with unprecedented levels of luxury and technology.

Rugged Capability Meets Premium Design

The AT4 Ultimate trim establishes a new standard in the Yukon lineup, striking an ideal balance between rugged performance and refined luxury. The exterior commands attention with its bold presence, featuring distinctive AT4-specific design elements that signal its adventurous spirit. Inside, the cabin showcases an exclusive Obsidian Rush interior that sets this trim apart from its siblings. The premium atmosphere is enhanced by three rows of full-grain leather seating, complemented by sophisticated Ash Burl wood accents throughout the cabin. Each design element has been carefully selected to create an environment that feels both luxurious and purposeful.

Advanced Off-Road Performance

The AT4 Ultimate backs up its rugged appearance with genuine off-road capability. The sophisticated Four-corner Air Ride Adaptive Suspension system can elevate the vehicle up to 2 inches, providing enhanced ground clearance when navigating challenging terrain. This advanced suspension system works in harmony with the specially engineered 20-inch wheels wrapped in all-terrain tires, delivering confident handling both on and off the beaten path. A robust front skid plate provides essential protection for the vehicle's underside, allowing drivers to explore with confidence.

Technology and Safety Integration

At the heart of the AT4 Ultimate's cockpit sits a stunning 16.8-inch diagonal Premium GMC Infotainment Center with vertical interface. This advanced system allows for customized integration of maps, audio controls, and vehicle diagnostics in an intuitive layout. The available Night Vision system enhances confidence during low-light driving conditions by identifying pedestrians and animals through thermal detection. The AT4 Ultimate also offers Super Cruise capability, allowing for hands-free driving on compatible roads across North America. These features are complemented by a comprehensive suite of safety technologies, including Front Pedestrian and Bicyclist Braking and Intersection Automatic Emergency Braking.

Premium Comfort and Convenience

The AT4 Ultimate's interior showcases GMC's attention to detail through its expertly crafted three-row configuration. The seats feature a new exclusive leather style with distinctive stitching patterns that reflect the trim's premium position. An available panoramic sunroof bathes the cabin in natural light, creating an open and airy atmosphere for all passengers. The addition of an 8-inch diagonal rear climate control touchscreen ensures that comfort can be precisely managed throughout the cabin.

The 2025 GMC Yukon AT4 Ultimate delivers a sophisticated driving experience without compromising the rugged DNA that defines the AT4 brand. By combining advanced technology, refined comfort, and genuine off-road capability, the AT4 Ultimate creates a new standard for premium SUV excellence.
