The Off-Road SUV Looks To Send It Through The Snow

GMC Yukon AT4

In the mountains of Vail, Colorado, GMC has taken the liberty to show off its latest breadwinner: the 2021 GMC Yukon. While the standard model is already an impressive piece of kit for the road, the brand looks to take things into the trails with the 2021 GMC Yukon AT4 off-road SUV.

The all-new 2021 GMC Yukon AT4 joins the Sierra AT4 and Canyon AT4 pickups, as well as the Acadia AT4 in GMC’s more adventure-ready line-up. With the edition of the full-size SUV in AT4 trim, GMC is slated to offer the AT4 sub-brand across their entire product line by the end of 2020. Like its fellow AT4 products, the Yukon AT4 carries a number of changes over the standard eight-passenger family hauler to improve its performance when the road ends.

Mechanically the 2021 GMC Yukon AT4 takes a note from Sierra AT4, with a unique front fascia, a two-speed transfer case and four-wheel drive coming as standard. The package also includes electronic aids by way of GM’s Traction Select System featuring off-road mode, as well as Hill Descent Control. 20-inch Goodyear all-terrain tires are fitted to help make the most of the Yukon AT4’s off-road capability, with underbody skid plates in place to add to the drivers peace of mind on the trails.

Perhaps the most interesting piece of hardware on the Yukon AT4 is the optional four-corner Air Ride Adaptive Suspension, which allows the off-road SUV to offer an additional 2 inches of ground clearance upon raising the suspension. This allows the truck to have an impressive 32-degree approach angle, for added off-road clearance. This system also lowers the SUVs ride height at highway speeds for added efficiency, while featuring the ability to drop the Yukon AT4 even further for ease of entry and exit once you’ve reached your destination.

Inside the Yukon AT4 features a Unique Jet Black interior color theme with Brandy accents, AT4-exclusive leather appointed seats and stitching, a heated steering wheel, as well as heated and ventilated front seats and heated second-row seating.

The Yukon AT4 will also benefit from having the most powerful engine in the full-size SUV segment as an option, thanks to the 6.2L L87 V8 with Dynamic Fuel Management which should produce an estimated 420 horsepower and 460 lb-ft of torque, paired with a standard 10-speed transmission as the sole transmission option. The 355 hp/ 383 lb-ft 5.3L L84 V8 found in the Sierra AT4 pickup will serve as the standard engine option. And while the 3.0L Duramax diesel will not be offered on the Yukon AT4, the off-road SUV will receive a 3.42 rear axle ratio (compared to the standard 3.08).

The first ever GMC Yukon AT4 could be just what the full-size SUV segment is looking for, which is also a space that GM has dominated for quite some time. With the popularity of luxury SUVs on the rise, producing an adventure-ready variant seems like a no brainer for GMC.
