GMC revealed its all-new 2021 Yukon and Yukon XL full-size SUVs on Tuesday, complete with a new independent suspension system, an off-road-focused AT4 trim, and an available Duramax diesel straight-six engine.
The Yukon is basically a re-skinned, more luxurious version of Chevrolet’s new Tahoe and Suburban, so prepare to see many of the same updates. The trucks have grown slightly in size versus the previous generation, and buyers now have three choices of engine: The standard 5.3-liter V-8, a 6.2-liter V-8 making 420 horsepower and 460 lb-ft of torque, and a 3.0-liter Duramax turbodiesel—a first for the Yukon.
All three engines send power to the wheels via a 10-speed automatic transmission and a four-wheel-drive system. There’s also an available “Active Response 4WDTM” feature that pairs a limited-slip different to a system that actively monitors road conditions to ensure maximum traction at all times.
The high-spec Denali trim gets a larger, more detailed chrome grille, paired to LED exterior lighting. For the first time ever, GMC is giving Denali Yukons an entirely different dashboard and instrument panel, along with unique seats and four different color schemes to choose from. Also standard on the Denali are a 360-degree camera system, a 15-inch head-up display, rear pedestrian alert, and magnetic ride control. Options include 22-inch wheels, air ride suspension, and a panoramic sunroof.
For 2021, GMC is introducing a new off-road trim dubbed the AT4. It gets a unique fascia with rugged looks, two tow hooks, and a skid plate, along with a slew of other improvements. There’s hill-descent control, an off-road drive mode, all-terrain Goodyear tires, and a two-speed transfer case as standard, with air ride available as an option. With the air suspension installed, the AT4 can provide an extra two inches of ground clearance, and a near-32-inch approach angle.
The Yukon and Yukon XL will be built at GM’s Arlington, Texas assembly plant, with production set to begin in Summer 2020. GMC says pricing and further specifications (like power output for the base and diesel engines) will be released closer to production.
