The beloved GMC Yukon enters its fifth generation with an all-new design for the 2021 model year. The most notable changes include a longer wheelbase for more interior space and a redesigned cabin with a premium look and feel. The 2021 GMC Yukon is available in four trim levels: SLE, SLT, AT4, or Denali.


The Yukon is available with three engine options. Standard on most Yukon models is a 5.3-liter V8 rated at 355 horsepower and 383 lb-ft of torque. Exclusive to the Denali model is a 6.2-liter V8 that delivers best-in-class 420 horsepower and a robust 460 lb-ft of torque. An available 3.0-liter turbo-diesel is also offered, which can output 277 horsepower and 460 lb-ft of torque while averaging high fuel efficiency.

All three engines come paired to a 10-speed automatic transmission. Rear-wheel drive is standard on most versions of the Yukon, though four-wheel drive comes standard on the AT4 trim and is an option on all versions. When equipped with the available Maximum Trailering Package and 5.3-liter V8, the 2021 Yukon can tow up to 8,400 pounds.

The Yukon also offers the all-new available Active Response 4WD™ System and the available Four-Corner Air Ride Adapative Suspension, a first-in-class system, for unparalleled performance on any terrain.

If you are looking for more rugged capabilities, choose the AT4 trim with off-road features like all-terrain tires, a ski plate, and front tow hooks.


The Yukon has three rows of seats for seven, eight or nine passengers, depending on if you prefer bench seats or captain’s chairs.

This model year, the SUV brings more space for your crew and their belongings. Third-row passengers now have 34.9 inches of legroom and there’s now 25.5 cubic feet of cargo space behind the third row — both welcome enhancements. Keep your small essentials within reach thanks to the available Power-Sliding Center Console, which includes a hidden storage drawer to conceal special items.

Aluminum accents and leather seating surfaces with accent stitching create a stylish look and comfortable interior in the SLT and SLE models. The fierce attitude of the Yukon AT4 is on full display in the cabin courtesy of Jet Black details, dark brush aluminum accents, and AT4 badges embossed on the head restraints of the front seats.

Your drives will be more enjoyable when you choose the available panoramic sunroof. The dual panes allow in plenty of light and fresh air. A power sunshade lets you easily let as much or as little sunshine in as you want.


The redesigned 2021 Yukon is a modern SUV packed with advanced technology. It comes standard with a 10.2-inch touch screen with the latest General Motors infotainment system. You can utilize the standard Apple CarPlay® and Android Auto™ compatibility to sync your phone’s screen to the vehicle’s touch screen.

The Yukon boasts a maximum of eight USB ports, one 12-volt power outlet, and two 110-volt power outlets to help power compatible devices. Premium available tech features include a wireless charging pad and a navigation system.

The available Rear-Seat Media System will help keep your passengers occupied on even the longest drives through Illinois. The two 12.6-inch high-definition screens located behind the front-row headrests clearly display your children’s favorite movies or shows.
The next generation Yukon Denali overflows with luxury and an exclusive design for the cabin, centered around a signature instrument panel. You can choose from among four color themes to outfit the interior to your personal style. Premium leather seats and authentic wood complete the sophisticated look. The Bose® Performance Series Audio System uses 14 speakers with Centerpoint® surround sound to flood the cabin with a high-quality aural experience.

The signature Denali Grille presents a bold element for the exterior. Its 10,000 reflective surfaces and chrome finish cast a brilliant look in motion.

The Yukon Denali has an overall length of 210.0 inches, while the XL Denali stretches to 225.2 inches. Behind the third row, you will have 25.5 cubic feet of space to fill in the Denali, but if you need more, the XL Denali offers 41.5 cubic feet of space.
