2025 Yukon AT4 Ultimate: GMC's Most Sophisticated Off-Roader Yet

November 22 2024

The automotive landscape undergoes a significant transformation with the introduction of the inaugural GMC Yukon AT4 Ultimate, signifying a considerable advancement within the luxury SUV segment. This new flagship trim delivers unprecedented refinement while maintaining the rugged capability that defines the AT4 nameplate. Canadian drivers gain a vehicle equally suited to urban sophistication and backcountry adventure.

Elevating the AT4 Legacy

The 2025 Yukon AT4 Ultimate builds upon five years of AT4 sub-brand excellence. GMC engineered this premium trim to exceed expectations in luxury and capability. The AT4 Ultimate creates a new category of vehicle that refuses to compromise on comfort and competence.

The powertrain options deliver exceptional performance for every driving scenario. The available 6.2L V8 engine produces 420 horsepower and 460 lb-ft of torque. For the first time in AT4 trim, drivers can select the 3.0L Duramax Turbo-Diesel engine, generating 305 horsepower and 495 lb-ft of torque. This power combines with a 10-speed automatic transmission to deliver smooth, confident performance across varying terrain.

Capability Meets Sophistication

The AT4 Ultimate backs its premium positioning with substantial off-road hardware. The front skid plate and 20-inch wheels with all-terrain tires provide fundamental trail capability. The Four-corner Air Ride Adaptive Suspension system raises the vehicle up to 50 millimeters, improving ground clearance when navigating challenging terrain.

This advanced suspension system automatically adjusts to changing conditions, maintaining optimal ride height and comfort whether crawling over obstacles or cruising highways. The system also lowers the vehicle at highway speeds to improve aerodynamics and fuel efficiency.

Premium Interior Experience

The Obsidian Rush interior transforms the cabin into a sophisticated retreat. Full-grain leather seating spans all three rows, complemented by Ash Burl wood accents. The unique leather seat styling features distinctive stitching patterns and premium materials that elevate the interior ambiance.

The centerpiece of this premium environment is the 16.8-inch diagonal Premium GMC Infotainment Center. This vertical interface allows customizable integration of maps, audio controls, and vehicle diagnostics. The available 8-inch diagonal rear climate control touchscreen ensures passenger comfort throughout the cabin.

Advanced Technology for Every Journey

The AT4 Ultimate introduces Night Vision technology to the GMC portfolio, enhancing confidence during low-light driving conditions. This system uses thermal detection to identify pedestrians and animals, displaying alerts through the head-up display and driver information center.

The available Super Cruise hands-free driver assistance system covers an extensive network of compatible roads across Canada, expected to reach 1.2 million kilometers by the end of 2025. This technology delivers hands-free driving and trailering capabilities, reducing driver fatigue on long journeys.

The 2025 Yukon AT4 Ultimate arrives at Canadian dealerships by the end of 2024, characterizing the perfect fusion of luxury and capability. This revolutionary trim level delivers the sophistication modern drivers demand while maintaining the authentic off-road capability that defines the AT4 name.
