2021 GMC Yukon delivers as an upscale full-size SUV

GMC redesigned the Yukon for 2021, adding some refinement to the truck-based three-row SUV. The 2021 Yukon is six inches longer than its predecessor, adding a bit of leg room for third-row passengers, or cargo capacity when the second and third rows are folded down. GMC also classed up the interior of its SUV, giving it some breathing room from its corporate cousin, the Chevrolet Tahoe.

The Yukon still drives like a truck with a backpack on. Unlike more car-like crossovers like the Kia Telluride, it can be a chore to drive around town and in parking lots, but its hefty towing capacity may make up for it. The GMC SUV comes in a handful of trims, from the pricey Denali to the off-road friendly AT4 all the way to the more economical SLE.

5 reasons to buy the 2021 GMC Yukon

What We Like:

Storage: There is more than 25 cubic feet of storage available behind the third row; folding the second and third rows down gets you more than 120 cubic feet of storage. That's more than the Ford Expedition and Toyota Sequoia. The Yukon can also tow up to 8,000 pounds when properly equipped, making it a solid hauler in its own right.

Technology: Wireless Apple CarPlay® and Android Auto are standard, and the Yukon boasts plenty of places to plug in your devices for charging. Otherwise, the SUV's tech features are functional if not flashy. The Yukon offers a handful of driver aids but many aren’t standard, so check the features list of individual vehicles carefully.

Interior: The extra length of the Yukon makes its interior a comfortable, or at least spacious, place to spend your time. While it's nice, and an upgrade on the Tahoe, it's not fancy when compared to more refined SUVs like the Mercedes-Benz GLS or BMW X7. Think “functional luxury” and you’re on the right track.

What Needs Improvement

Fuel Economy: The Yukon gets an EPA-estimated 16 mpg combined. That's worse than the Ford Expedition (EPA-estimated 19 mpg combined) and quite a bit worse than the Mercedes-Benz GLS and BMW X7 (EPA-estimated 21 mpg combined).

If towing is important to you, that sacrifice might be worth it.

Image of Chevrolet Tahoe

The Chevrolet Tahoe has all the size and space. The 2019 Chevrolet Tahoe is available with two engine choices and a six-speed automatic transmission. A front-wheel-drive 2019 Chevrolet Tahoe with the 5.3L V8 engine can tow up to an estimated 8,600 pounds when properly equipped.

This gives you a lot of options if you're looking for a capable people-mover or you’re looking to take a small caravan or boat away on a trip.

There are three trims available to buy: LT, LS, and Premier. The base-level LS trim includes features like Android Auto, Apple CarPlay®, tri-zone automatic climate control, and a six-speaker audio system.
