2021 GMC Yukon AT4

Following the breakout popularity of the new Sierra AT4 pickup and the more recently launched Sierra HD AT4 and Acadia AT4, the new 2021 GMC Yukon AT4 is squarely focused on rugged adventure. GMC will offer the new AT4 sub-brand across all product lines by the end of 2020.

“Our mission with the next-generation Yukon was to create an off-road capable vehicle with a premium interior, advanced technology and class-leading space for eight people and their cargo,” said Jim Danahy, executive chief engineer of full-size trucks.

Successor	2022 GMC Yukon AT4

The 2021 GMC Yukon AT4 provides premium off-road inspired design cues to match its strong capability. The first-ever Yukon AT4 features a unique front fascia that both visually carries the rugged all-terrain look and supports off-road capability. Coupled with the available four-corner Air Ride Adaptive Suspension, the AT4 can raise and offer an additional 2 inches (50 mm) of ground clearance. When at this maximum height, the Yukon AT4 offers a nearly 32-degree approach angle for added off-road capability. AT4 provides a contrast to Denali’s chrome-oriented look around the exterior, with trim characterized by body color or dark accents throughout, as well as a pair of red recovery hooks, similar to the Sierra AT4.

Key features of the AT4 include:

Two-speed transfer case
20-inch Goodyear all-terrain tires
Traction Select System with off-road mode
Hill Descent Control
Skid plates protecting key areas of the underbody
AT4-exclusive leather appointed seats and stitching
Unique Jet Black interior color theme with Brandy accents
Heated steering wheel, heated and ventilated front seats and heated second-row outboard seats
