(L to R) 2021 GMC Yukon AT4 and Denali

GMC has finally released the updated pictures and specs for its new 2021 Yukon line.

GMC has now taken its turn in releasing the full specs and image gallery for the all-new Yukon and Yukon XL line. Before we go too far, please note the prior story on the Suburban/Tahoe line we covered in-depth one month ago:

You can also watch the live reveal of the Suburban and Yukon right here in full HD. You won’t find this video on the GM site. Our own Zane Merva captured it live.

The all-new 2021 Yukon and Yukon XL ride on a new platform, are larger inside than the prior generations, and have an all-new suspension setup.

With a nearly 5-inch-longer wheelbase and 6.1-inch increase in overall length compared to the current model, Yukon offers 41 percent more third-row legroom and 66 percent greater cargo volume behind the third row. Maximum cargo room increases by 30 percent

All of the best applicable new features of the updated Sierra and Suburban/Tahoe are to be found on the new Yukon SUV line and the Yukon will now have an AT4 variant for better off-road capability. “GMC Yukon is the full-size premium SUV that’s made to be used,” said Duncan Aldred, vice president of Global Buick and GMC. “The new Yukon delivers what customers value most – premium features, purposeful technology and all-terrain capability.”

2021 Yukon and Yukon XL – One Paragraph Synopsis

Data dumps are great, but we know fans want the straight scoop. Here it is:

Interior: All-new interior design across the Yukon lineup, highlighted by a Denali-exclusive interior and a new, class-leading available Power Sliding Center Console. A class-leading available 15-inch-diagonal multicolor Head-Up Display projects speed, navigation, safety features and other driver-centric information when properly equipped.
Suspension and Driveline: First-in-class, available, four-corner Air Ride Adaptive Suspension delivers exceptional ride comfort and, when 4WD LO is engaged, allows drivers to raise the body up to 2 inches for additional ground clearance when traveling off-road (late availability). A new available Active Response 4WDTM System combines technologies including an electronic Limited Slip Differential, to continuously monitor road conditions and react to improve traction, handling and overall control. Then there is Magnetic Ride Control.
Trailering: Nine camera views are now available, the most in the segment, increase driver awareness, including High Definition Surround Vision, Rear Camera Mirror and GMC’s ProGrade trailering system.
Engines: The most powerful engine in the full-size SUV segment, an all-new 6.2L V8 with Dynamic Fuel Management (standard on Denali) delivers an estimated 420 horsepower, paired with a standard 10-speed transmission. Yup, the 3.0-liter diesel is an option.

2021 GMC Yukon Denali

Yukon Denali

GM’s “Alaska Mountains Alaska Mountain” trim earns the business of 60% of Yukon shoppers. With the new generation, the Yukon Denali becomes more special. Each Denali has a unique interior differentiated from the rest of the Yukon lineup. Denali will have four color schemes. Each of the four color  includes real wood trim, with a natural texture. The leather surfaces in the Denali Yukons are cut and stitched by hand in a unique Denali pattern. “Yukon was the model in which Denali originated in 1999, and now more than 20 years later, we’re introducing the quintessential Denali,” says Helen Emsley, executive director of Global Buick and GMC Design. “It delivers a first-class experience with an all-new, exclusive interior and a bolder, more distinctive exterior design.”

Power Sliding Console

Available on Denali, AT4 and SLT, the power sliding console moves Yukon’s main storage console between the driver and passenger seats. It is able to slide back up to 10 inches, offering an expansive storage area that GMC says enhances overall storage flexibility and organization.

The console also offers hidden storage. When back, front seat occupants gain access to an open space for a purse or bag. There is also an additional hidden drawer underneath the console’s main storage bin, which provides secure storage and additional peace of mind (everyday carry?).

GMC will offer the new AT4 sub-brand across all of its product lines by the end of 2020. The Yukon AT4’s unique front fascia and rugged all-terrain look offers buyers a choice to Denali’s chrome-oriented look around the exterior. The AT4 also has capabilities that back up its off-road vibe. “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.

-Two-speed transfer case
