The all-new 2024 GMC Acadia debuts the crossover’s latest third generation, and with it, a long list of updates and changes. Some of the most impactful changes are new exterior and interior dimensions, with the next-gen Acadia measuring in with sizable increases to overall length and passenger room, among other metrics. In fact, the 2024 GMC Acadia is the biggest Acadia ever, even out-measuring the full-size first-generation model, as outlined in the following GM Authority Dimensional Comparison.
Exterior Dimensions
Let’s start outside, where we find the third-generation GMC Acadia out-measures the previous second-gen crossover by a significant margin, with an overall length that’s 10.6 inches longer, a wheelbase that’s 8.9 inches longer, an overall width that’s 4.2 inches wider, and an overall height that’s 4.3 inches taller.
Interestingly, the third-gen Acadia is larger than the first-gen model as well, and by a significant margin to boot, with a wheelbase that’s more than two inches longer, an overall length that’s 3.26 inches longer, an overall width that’s 1.36 inches wider, and an overall height that’s just over an inch taller.
The only dimension where the first- and second-gen Acadia show larger measurements than the third-gen is in ground clearance.
First Gen | Second Gen | Third Gen | |
---|---|---|---|
2007 – 2016 (2017 Limited) | 2017-2023 | 2024 – present | |
Wheelbase (in.) | 118.9 | 112 | 120.93 |
Overall Length (in.) | 200.7 | 193.4 | 203.96 |
Overall Width (in.) | 78.2 | 75.4 | 79.56 |
Overall Height (in.) | 69.9 | 66.7 | 70.97 |
Front Track (in.) | 67.1 | 64.5 | 67.6 |

Rear Track (mm) | 1704 | 1638 | 1709 |
Ground Clearance (mm) | 187 | 182 | 171 |
Interior Dimensions
Given the third-gen Acadia’s larger exterior dimensions, it should come as no surprise that the 2024 GMC Acadia’s cabin offers a good deal more passenger room than the preceding second-gen model. Second-row hip room and third-row hip room show the biggest increases at 5.1 inches and 5.7 inches respectively, while first-row legroom was increased by 3.3 inches, second-row legroom was increased by 1.8 inches, and third-row legroom was increased by 2.4 inches. Shoulder room was also increased by 2.6 inches, 3.3 inches, and 3.6 inches on the first, second, and third row, respectively.
To drive the point home even further, the third-gen Acadia is also larger than the first-gen Acadia with respect to nearly every interior metric, with the exception of third-row headroom and third-row legroom, albeit marginally so.

As a reminder, the 2024 GMC Acadia cradles the turbocharged 2.5L I4 LK0 gasoline engine, as GM Authority was the first to report. The 2024 GMC Acadia rides on the GM C1 platform, while production takes place at the GM Lansing Delta Township plant.

Hope to see more generation comparisons of GM vehicles.
It also comes with the smallest engine ever.
And most powerful! Isn’t technology grand?
Not always. An overworked 4 cyl turbo with AFM. No thanks. The wife has been waiting for ’24 to come out, but on this news she’ll keep the Honda Pilot that she dislikes.
Not always, no. But it’s backwards thinking IMO to automatically assume the engine is “overworked” when a manufacturer is spending millions to develop an engine for a specific platform, just because it has a lower displacement than before. Modern turbos are reliable, wouldn’t argue more reliable than NA but reliable to 150-200k miles, before mentioning the increases in power and fuel economy.
Where’s the cargo space specs ?? Many don’t use the back seats but need the cargo capacity…
As a GM fan & owner of two(2) Envoys both XL versions & one being the Denali with the 5.3v8 I wanted something different but comparable in size & utility to upgrade to & was wishing GM would bring the Envoy back or create something better or comparable but unfortunately for me this isn’t what I thought it would be! I love the Envoys body on frame layout & the rear wheel drive functionality! This just doesn’t cut it for me so I guess I’ll keep on trucking with my Envoys until GM creates something more suitable for my liking! A new Envoy would be nice GM but not like you did with the Trail Blazer please! Keep it true to the original size & functionality platform with better interior design & ergonomics & I’ll be in line for another go but until then Envoyin myself!
How is it bigger if the third row legroom is still an inch short compare to the first gen? I know it’s significantly bigger than the second gen for sure. Also is there spec for comparing the first, second, and third gen traverse?
They can change all cosmetics inside & out they want. But it is the electronics that are the core problem. We have a 2017 Acadia SLT. We have heard from other Acadia owners all the way to 2023, having similar issues. First is a Check Suspension caution. Dealers charged $$$ to attempt to fix. No joy. No code set makes harder to fix. Second is dashboard looks to be possessed. Driving and all of sudden radio displays cycling through every option. Your speed display shows all options to choose like phone, radio, light & door options, etc. Dealer needs a $1,200 computer change. Third. Driving and all of a sudden your Temp indicator goes to zero (cold). The cooling kicks on high speed to cool engine. No heat in cabin. Temp thermostat replacement $1,000. It’s not in front for easy change you can do. It’s in rear of engine bay, have to pull intake manifold and other parts. Now a two hour job. Fourth. You shut off the engine, you get Shift to Park caution every time. You have cycle the shifter. I have talked to many owners when I see one, they have similar issues. In other words, I will not buy a GMC again. Heard Sierra trucks and cars are have electronic problems. But hey, it still looks pretty.
Well, all of those issues stink. I have had 2 Acadias and picking up my 3rd one today. I have never had ANY issues with any of them and love my AT4s!
We have had Acadia’s since 2007. Really like the handling of this vehicle. We had 2 of the 1st gen with #1 having the timing chain & transmission issues. We bought new in 2015 with no real issues other than one annoying squeak when the temps are +5C down to -7C range. No squeaking in summer and also none when it gets really cold. Not one mechanic had been able to find the problem yet. A/C system has leaked very slowly in 2023. I did not want the 2nd gen due to the smaller size. I am enthused with the 2024 from what I read but going down to a 2.5L engine – hopefully that results in improved fuel mileage.
My 2008 Saturn outlook (Acadia’s sister) was my favorite “mom car” and “trip car” ever owned!
When it finally died in 2020, thought I knew what I wanted and went straight to the GMC dealer for a new Acadia. Boy was I disappointed!
For the first time in four generations I stepped outside the GM product line – wound up with a Hyundai Palisade. No complaints and it has served me well, but have always missed the girth and seating height of the Outlook!
Excited to get into a new Acadia and hoping it lives up to its 1st Gen size, feel and handling!
Does the new 2024 Acadia still have the thermostat placed like the 2017 Limited, with tearing apart part of the engine to get to it? I loved my Acadia but my husband who is an engineer was totally put off by the design. We also farm so he is pretty mechanically handy. We were stranded in the Colorado mountains for a week waiting for parts and service. Not a bad place to be stranded, but!!! We are now looking to replace it and I have looked at the Mazda CX 90, Honda Pilot and Telluride. Still like my GMC but no way will I get my husband to purchase if the thermostat and steering wheel fluid container is in the same place. The information on the power of the motor also concerns me. What do you all think?
