Heralding the arrival of Big Red’s third-generation three-row crossover, the 2024 GMC Acadia features many upgrades over the preceding model, including fresh exterior styling, vast improvements to the interior, and an all-new powertrain. With the third point in mind, today we’re checking out the Environmental Protection Agency’s (EPA) fuel economy ratings for the 2024 Acadia.
Before jumping in, here’s a quick review of the 2024 Acadia’s powertrain. Under the hood lies the turbocharged 2.5L I4 LK0 gasoline engine, rated at 328 horsepower and 326 pound-feet of torque. Meanwhile, the GM eight-speed automatic transmission handles the shifting duties through either a FWD or AWD setup.
It’s worth noting that the 2023 GMC Acadia was offered with the choice between the turbocharged 2.0L I4 LSY gasoline engine, rated at 228 horsepower and 258 pound-feet of torque, and the naturally aspirated 3.6L V6 LGX gasoline engine, rated at 310 horsepower and 271 pound-feet of torque. Interestingly, the second-gen Acadia utilized the GM nine-speed automatic transmission.
With that covered, here’s 2024 GMC Acadia fuel economy figures:
Model | 2024 Acadia | 2024 Acadia | 2023 Acadia | 2023 Acadia | 2023 Acadia | 2023 Acadia |
---|---|---|---|---|---|---|
Engine | Turbo 2.5L I4 LK0 | Turbo 2.5L I4 LK0 | Turbo 2.0L I4 LSY | Turbo 2.0L I4 LSY | 3.6L V6 LGX | 3.6L V6 LGX |
Transmission | 8-speed auto | 8-speed auto | 9-speed auto | 9-speed auto | 9-speed auto | 9-speed auto |
Drivetrain | FWD | AWD | FWD | AWD | FWD | AWD |
City MPG | 20 | 19 | 22 | 22 | 19 | 19 |
Highway MPG | 27 | 24 | 29 | 27 | 27 | 26 |
Combined MPG | 23 | 21 | 25 | 24 | 22 | 21 |
Looking over the numbers, we find that 2024 Acadia FWD units split the difference between the two 2023 Acadia FWD powertrains with a 23 combined mpg rating. Meanwhile, 2024 Acadia AWD examples are comparable to 2023 Acadia AWD units equipped with the larger 3.6L V6 engine at 21 combined mpg.
As for the differences, it’s worth noting that the all-new Acadia is bigger than the outgoing model, and thus likely heavier as well. Actually, it’s the biggest Acadia produced so far.
Speaking of increased size, the third-generation GMC Acadia moves to the long-wheelbase variant of the GM C1 platform, which now incorporates tech features like the GM Global B electrical architecture. Production has also been moved to the GM Lansing Delta Township plant in Michigan.

WOW what a Big difference, Now check the Towing RATE !!!
Samer as before, no change.
GM should have left the V6 9-Speed drive line alone and increased the V6 HP, the 310 hp V6 is a great smooth running economical engine and you gain practically nothing with the Experimental 2024 Acadia 4 Banger that is pushed to its Max limits!! I’ll sit this one Out!
Totally agree. Why not utilize the 2.7 that the trucks are using for a few years.
They did utilize the 2.7 L3B by reducing the stroke by 50cc to increase higher hp greater range over truck lower end torque.
Why? The V6 drove bad at lower RPM’s and had to be revved to make any power, not to mention any slight hill required a downshift. The new engine makes more power, especially in the torque department that matters most with these heavier vehicles, and gets better mpg. Not sure the love for the V6, it wasn’t fully in its element before. It wasn’t bad, this just shows what a proper motor can do.
That is funny you think the new motor is “pushed to its max”, not even close grandpa. The 2.7 that this was based on is built like a diesel and one of the hardest motors to kill in durability testing from sources close to the matter have stated.
OK When are they going to start building and delivering these 2 dealers..2025 is on the horizon…or is this some new GM concept? When did GM start dumbing down?
Already being produced and many in transit to dealers.
I own a 2019 Buick Enclave with the 3.6 engine and I get 25-26 mpg on the hwy. Saying that the new Acadia is bigger and heavier and that is why mpg is less with the 2.5 turbo is not right.The new Acadia is the same size as my Enclave. GM should have left things alone with the 3.6 9 speed.The 2.5 turbo will be a dud for the Acadia as well as the 2025 Enclave. I’m going to wait and see what GM does for 2026 before I purchase another on of their vehicles.
The MPG isn’t less, it is more in the FWD and the same in the AWD version. Not sure how a bunch more power, especially in the torque department, while getting better or the same mpg is a dud, but ok, you know better…
I’m trading my 2022 V6 Acadia by end of year for a top line V6 Buick Enclave while they last, they ride handle and far superior to Acadia with great cargo space!!
GM is SO far behind the curve! Amazing they stay in business.
How so? They just gave it a big power bump with a slight bump or the same mpg with a bunch more standard features. Still looking for that behind the curve reasoning…
I really like the new Acadia, and I’m glad they dropped the 3.6L. I had it in my 22 XT6 Premium Luxury and I absolutely hated it! Nevertheless, it makes no sense to be going backwards with MPG in the Acadia.
That is nonsense, I owned 2 310hp V6 Acadia’s and a 310hp V6 Terrain and they were all good smooth running economical imagines which is why I stayed with GM, not doing the beefed up turbo 4 banger, sitting this potential disaster Out!
Maybe he should be more clear on what he didn’t like about the 3.6, then maybe you wouldn’t say it is nonsense? I bet it is because the motor lacks torque and needs to be revved to make any power and requires a down shift at any change in incline or head wind. You can’t lug the motor either. Not saying it isn’t smooth (though it could be better), it just doesn’t have the proper power delivery for heavy vehicles which this new motor fixes.
What is with the dated thinking that a smaller motor can’t move a larger vehicle for long periods reliably? Technology can easily eclipse historical figures reliably. Back in the day a diesel made what, 200 hp and 500 foot pounds of torque? Now they have more than doubled that in the same size motor. But based on sheer cylinder count a four cylinder can’t get a 50% increase and be reliable? It is all how it is built, and it is well known the 2.5/2.7 family is build like a diesel, reliability will not be its issue. No disaster here, the 2.7 in a full size truck has done very well, no reason a smaller vehicle with a slight displacement reduction won’t have a problem.
Come to the present, you will like what they are doing here!
The 3.6 v-6 was a great engine and there was no good reason to get rid of it. Another stupid decision that will cost GM customers.
There were tons of great reasons, first and foremost it wasn’t properly set up for this size of vehicle in terms of its powerband. It has no low end torque and has to rev and down shift to do anything, not good in a large heavy vehicle. Not sure why customers won’t be happy about a solid HP bump, large torque bump where it matters most in an engine that is built solid like a diesel. Only the uniformed would make that decision/comment…
TMI you talk a great story and I assume you do not even own a 2024 Acadia, however, most buyers are not interested looking at 4cyl vehicals. We happen to prefer quite smooth running V6 / V8 power, maybe bring the small block V8 back. I know the difference and I’m not interested in buying a 4 cyl again! GM should have just improved the 310HP V6 and bumped that engine up and added the turbo now that would be a great mid Size 2024 Acadia improvement!
With gas prices never being “cheap” again in our lifetime, I struggle why people love V6/V8 engines. In the old days, when gas was $.99/gallon or less, it made sense. With prices surging over the littlest of things, driving those large motor vehicles is expensive. The 4 cylinder motor is not what it once was with all the new technology, which is what TMI’s point was…
Matt I agree, however the savings in mpg with the 4 cyl is crumbs, I tried the 2022 4cyl turbo and took it back after 3 months and traded back for a 22 V6 Denali there was Zero benefit and the engine was noisy and not smooth like the 310hp V6. That said, they need to market a significant improvement in fuel savings to get the average buyers attention and as of Today GM has failed to do this! My 2001 LS 1 V8 6spd Vette gets close to 28mpg cruising in #6 go figure this MPG game out!
GM, in my opinion, don’t have a choice. EPA is dictating what they can do with their technology. Why would they plan on Cadilac becoming all electric? The home of CTS-V Blackwings and Escalades-Vs. For every vehicle they produce that is not making the mark on the EPA’s MPG and “Smog”, they get fined. Only way to counter this is using carbon credits. If they don’t have the carbon credits, they have to buy them from competitors. Ram/Dodge shelled out 3 to 4 billion to Tesla for their credits. The fine is much more if they don’t have the credits…. I believe the big three did create this issue over years of lobbied self-induced regulations keeping small companies from starting and it came back to bite them.
My most recent concern is part availability. If you are looking at new, talk to a service rep and ask if they are having issues getting parts for their vehicles and inquire about the models you are looking at. I have a ’22 Silverado LTZ loaded 6.2 18,000 miles it was in for knocking and loss of power. It was in the shop waiting on a water pump gasket for over a month. They could only get the part if they bought the pump with it. GM “Loyalty” was notified. Now 4 months later and at another dealer the truck is still not fixed. The new dealer ordered an engine which came in but cannot get the radiator. They do not want to put it back in service in fear of metal in the oil cooler of the radiator. Dealer stated the part is at other locations, but those dealers do not want to give them up for availability from GM is limited/backordered. Don’t expect GM to help, Loyalty department strings you along until you cry Lemon Law and then Lawyers get involved. Funny that I have an old 2005 Avalanche that I can get any part for to do with the drive train within 2 weeks normal shipping. I guess my grandfather was right, they don’t make them like they used to. BTW Ram, Ford, Toyota have the same issues.
