Making its formal introduction for the 2024 model year, the third-generation GMC Acadia introduces a wealth of updates and changes, including new styling, a new cabin, a new powerplant, and the latest tech features. Additionally, the all-new 2024 GMC Acadia is significantly larger than the preceding model, offering a big boost to interior room as well. Now, we’re taking a closer look at the 2024 GMC Acadia in the following GM Authority Dimensional Comparison, placing the next-gen crossover’s exterior and interior measurements alongside those of the preceding second-gen crossover.
Exterior Dimensions
Looking over the exterior dimensions of the all-new 2024 Acadia, we find the third-gen crossover is larger than the preceding second-generation in nearly every single measurement. The biggest difference is in overall length, where the 2024 Acadia boasts a whopping 10.6 inches of extra length, and the wheelbase, where the new Acadia is nearly nine inches longer. Meanwhile, overall width and overall height have both increased by more than four inches, while the front and rear track are both about three inches wider.
Notably, the 2024 Acadia is also a little closer to the ground with a 0.4-inch reduction to ground clearance compared to the preceding generation.

Ugh a 4-cyl turbo, no thanks.. I like the rest though. No chance I’ll ever buy an EV or a Turbo.
I have a “before shrikage” 2017, i.e. original body style. How does the revamped 2024 compare dimensionally to mine? Have you reinvented the wheel?
How about a comparison of the Gen1 to Gen3? Loved the Gen1. Walked away from the Gen2.
More than a marketing ploy to make the size of the Acadia more Yukon like. Families will benefit from the increased size. I hope with the extra length GM was able to get rid of the drivers side wheel well protrusion into the drivers leg space. I have owned Yukons since 2004. Will definitely check out the new Acadia.
Appreciate vehicle comparisons.
This article has me very interested in buying. Wife and I have decided to buy a new car for her this year. Her last two cars were Buick Enclaves. However, since kids are gone we have decided to downsize from the Enclave. The earlier Acadia seemed too small. I have been looking into Audi Q 5, BMW 5 series SUV, Cadillac X5 suv and others.
One thing I would like to know, is the Acadia and Buick Envision the exact same size?
As far as someone complaining about the 2.5 cylinder Turbo, I think if he drove one he might change his tune.
@John K…..I think he was complaining because it’s a 4 cylinder and a turbo. Look, GM should have just kept the 3.6L and tweaked it a bit and given it the Camaro’s HP/TQ ratings. Also they could have just turbo charged the 3.6L for a high performance “SS” version/”Typhoon” version to give ST Explorer a competitor. Right now it has nothing.
Turbo vehicles don’t get their MPG’s when they are worked, or driving up many hills on a long trip. Case in point, my step dad had the Furd EcoBust and that thing NEVER EVER got it’s MPGs it was supposed to and he drives it very conservatively!!! He averaged around 17 mpgs with it. Never got above 18 mpg with it, for the 135k miles he owned it for.
My four K2 GMC Sierra’s, two with the 5.3L averaged 21 mpg or better, and my two 6.2L averaged right at 20 mpgs. For comparison to our lake house traveling 75 mph…I’d average always above 21 and he stayed below 17. Same distance, day, weather, mph!!
He has since gotten rid of it and now is on his second T1 GMC Sierra with 5.3L and 10 speed combo. He averages 20. Loves it.
I just despise the lag in turbo’s. It’s always when sitting in intersection trying to take a left.. finally a window opens up, step on the gas, and bog.. That 1-2 second bog down matters… I will never own a turbo because of this. EVERY single turbo on the market has this issue.
Too bad the 2024 Acadia Denali aren’t being built as of yet. Can’t wait to purchase my build when they start, hopefully in March 2024.
Thanks a lot GMC – When we traded in our 2016 Acadia for the 2019 Acadia she drives now, my wife complained that the 2019 is so much smaller. Now that the 2024 goes back to the original size she wants a new one…
That said – I’m kind of liking the 2024 as well.
Good luck finding many in this category soon without a turbo 4. V6 are going bye bye. Besides the power on the Turbo 4’s are where its most usable.
I’ve had GM cars and trucks for decades and most were good. But, I’ve also been stuck a few times with GM experimental engines that were dogs and fell apart. Remember the 80’s Diesel from a gas engine, the V4,6,8 and who could forget the Pontiac Tech 4. I’ll pass on this turbo for now. Buying the first foreign car in decades. The Honda Pilot is running a standard V-6 and has all the current technology. Thanks but no thanks.
You mean the V8,6,4,0
I have a ‘20 AT4 as a work vehicle. I like the dimensions, find it a better handling vehicle than the ‘21 Traverse my wife had. The whole 4 banger turbo scares me a bit. These engines in this application, medium to large SUV configuration, haven’t been around long enough to see if reliability will prevail. These motors are under a lot of stress pushing 2 tons around.
Smaller displacement engines that are stressed with boosted intakes, are never going to be able to loaf along as easily as larger displacement, slower turning engines and no one ever seems to realize that the turbo is considered a “wear” item like brakes or tires and not one manufacturer has any built-in technology to cool and slow these turbos after hot shut-downs which starves them of oil and leads directly to “coking” and expensive replacement. Experience has demonstrated that when turbo engines are “pushed” to yield the performance of the larger engine, any claimed fuel mileage advantage disappears and may even be worse than the larger engine under the same conditions.
The good news is the turbo cooling issue is no longer a thing on these new engines. Modern turbo engines have electric motors that move coolant through the turbo and fresh cool oil when the engine turns off or is in idle. The head GM engineer on the 2.7L I4 turbo talks about how cooling of the turbo and longevity was the main priority. Also, the engine is designed like a diesel engine with this in mind. I understand this is the 2.5L version but they are practically identical. There is a video from TFL truck on YouTube if you would like to see it regarding the new turbo GM engines.
The Chevy guy mentions totally worthless “thermal siphoning” after shut down, not continued electric water pump operation and very glibly skipped over that. There is also no mention of continued oil supply after shut-down either, just that the turbo is the first recipient of freshly-filtered oil downstream of the oil filter. Thanks for the heads up but after viewing the You Tube video three times, he doesn’t claim what you are stating.
They clearly made a mistake with the smaller gen, trying to differentiate it from the Traverse and Enclave, only resulting in lost sales. But there’s now a HUGE gap between the Terrain and the Acadia, unless I’m forgetting a model. The Terrain does NOT need to grow as well.
The Terrain is too cramped. It needs to grow as well, and needs a larger turbo. Most small families that don’t need a 3-row, but need to move to a larger 2-row SUV when their kids grow up. The Terrain does not fulfill that need.
I wish GMC had 2 sizes for this like they do with the Yukon. The new version could have been called the Acadia XL. GMC could use a 2 row midsize SUV.
Can the 2024 Acadia be flat towed behind an rv
Everybody is missing the big question: what’s the CARGO specs now with both Traverse & Acadia? Still 97 cu. ft. behind front seats? After 7 Suburbans, and not being comfortable with HIGH HOOD of the new style, I’m finally downsizing and need the largest cargo area after the Tahoe/Denali. And will the Acadia have the heated wipers? Any advantage to the Acadia over the Traverse? “Inquiring Minds Want to Know”
How does the Cadillac 6 compare to Traverse/Acadia? Same cargo area? Any options not available with the other two?
No sign of curb weight, the 4 banger Will not get the Better gas mileage as V/6. Too much weight ,the Turbo will be Turning W/ your foot in it! And it says in last sentence 2.5 is standard ! How about 3.6 upgrade ??? I. Hope ! How about a2024 GMC Syclone ,Need more INFO.
I love my 2018 Acadia and the size is perfect. I think I will keep it indefinitely since GM will increase the size.
How about a comparison of Curb Weights?
While it might be nice to have larger dimensions, there will most likely be a weight penalty, and the slightly higher horsepower might not be up to the challenge or, at least, lead to a more sluggish vehicle.
With the current models, the larger Chevy Traverse weighs some 750 pounds heavier than the GMC Acadia.
Curb weights are not yet available… but once they are, we’ll write about it.
– AL
Any updates, yet?
Ugh the interior specs are smaller than my 2021 Honda Pilot. I was hoping it would be the same or bigger. Oh well, I will stick with my Pilot.
Get your checkbook out when 7 years or 105,000 miles rolls around on your Honda V6 Earth Dreams Pilot and you need to change out the timing belt on it. The shops will all tell you that when you shell out for that required maintenance that you should also replace your water pump, belt idler, and belt tensioner, change coolant and perform a valve adjustment and everyone quotes about $2550.00 for doing that. Haven’t heard yet what GM is doing on their Turbo four banger for timing belts or chains but the former 3.6 V6 they used in not just the Acadia had this nasty habit of stretching the OHC timing chains. The 2008 3.6 V6 in the Lambda platform was notorious for it.
Lose 10 pounds, you won’t even notice the dimension difference. 😀
