GMC Acadia vs. Yukon: Which Is Bigger?

In the GMC world of SUVs, bigger is often better. Right? The Yukon reigns supreme on big space. Or does it? GMC makes three three-row SUVs, the Acadia the Yukon and the giant Yukon XL. Is the Acadia really a better Tahoe alternative?

GMC Acadia vs. Yukon: which has more cargo space?

The easiest way to measure size is in the interior cargo room. The Acadia holds 79 cubic feet of cargo with all the seats folded, and 41.7 with the third row folded. But the Yukon? Well it holds 72 cubic feet behind the third row, and a massive 123 cubic feet of stuff behind the second row. For the even bigger Yukon XL, count on 145 cubic feet behind the front row and almost the same amount of space behind the third row as the Acadia has with the third row folded.

But, all of that space comes at a cost in sheer vehicle size. The Yukon is 17.5 feet long, and the XL is nearly 19 feet long, so good luck squeezing that into a Trader Joe’s parking space. The Acadia, however, is much better for city driving with a length of 16 feet, and it’s six inches narrower which helps a lot when you’re parking. The Chevy version of the Yukon is the Tahoe, while the Chevy Traverse is the Chevy version of the Acadia.

The Yukon has a lot of leg room

In the third row, the Yukon’s size really stands out, with 35 inches of legroom. That’s plenty for real adults to sit comfortably in the back. But, if you really need the room, the Yukon XL adds almost another two inches of leg room. If you’re carrying seven passengers regularly, the Yukon XL is your go-to SUV. But, if you’re only occasionally ferrying seven, maybe the easier-to-park Acadia is for you.

The Acadia is comfortable, but every dimension inside is just slightly smaller. The rear seat passengers still get a generous 30 inches of leg room, but that’s about 10 inches less than second-row passengers get.

The Tahoe has more power, too

The Acadia comes standard with a 2.0-liter turbocharged four-cylinder. Don’t let it’s small size fool you, it has 228 horsepower. The optional V6 makes a healthy 310 horsepower, which should be plenty. All Acadia SUVs get GMs 9-speed auto, which should help to maximize the power from either engine. You can also order it an off-road ready AT4 package with four-wheel drive.

While you can get GM’s mighty 6.2-liter in the Yukon with 420 horsepower, you’ll pay for that power both at the dealer, and the pump. You have to step up to the AT4 or Denali packages that start at about $76,000, and then you’ll only get 16 mpg combined. It comes standard with the 355-horsepower 5.3-liter V8 and, to the delight of many, you can still get the 3.0-liter Duramax diesel that helps with massive torque for towing.

How much is a GMC Yukon?

While the Yukon may be bigger, it’s also a lot more expensive. The Yukon starts at about $58,000, while an Acadia starts at about $39,000. The base Yukon comes well equipped, but the SLT for $66,000 has more of the options that most of us like, such as heated seats and wireless charging. The longer XL version starts adds about $3,000 to the base price.

The comparable upgraded Acadia SLT, however, starts at about $43,000, while the off-road focused AT4 starts at $45,000. With the money you save, you can always buy an extra trailer for the Acadia, which tows up to 4,000 pounds.
