General Motors is developing a brand-new third generation for the GMC Acadia crossover, set to drop for the 2024 model year. We’ve already seen the 2024 GMC Acadia testing as a camo-clad prototype, with spy photos providing us with an early look at the new styling and design. However, one of the big questions remaining to be answered is what will be under the hood. Now, GM Authority has learned exclusive details on the engine set to power the upcoming 2024 GMC Acadia.
According to GM Authority sources, the next-gen 2024 GMC Acadia will cradle GM’s new turbocharged 2.5L I4 gasoline engine currently in the final stages of development. GM Authority was the first to report on this new engine, with specs including a dual overhead cam (DOHC) arrangement and direct fuel injection. The new turbo 2.5L engine could be considered a lower-displacement version of the turbocharged 2.7L I4 L3B, or a “mini L3B,” with both engines following The General’s Cylinder Set Strategy, or CSS. The current CSS lineup also includes the turbocharged 1.3L I3 L3T gasoline engine, the turbocharged 2.0L I4 LSY gasoline engine, and the turbocharged 2.7L I4 L2R gasoline engine.
The 2024 GMC Acadia’s new turbocharged 2.5L I4 gasoline engine will be tagged with RPO code LK0, and, at this point, will likely be the only engine offered for the next-gen crossover. Output will be routed through the GM nine-speed automatic transmission.
Check out the exclusive GM Authority video below for more information on the new turbo 2.5L engine:
Although official output figures for the new 2024 GMC Acadia are still forthcoming, there is still some room to speculate. Assuming the new turbocharged 2.5L I4 LK0 gasoline engine shares identical specific output as the turbocharged 2.7L I4 L3B gasoline engine (114 horsepower per liter, 159 pound-feet of torque per liter), we can estimate that the 2.5L LK0 will produce around 287 horsepower and 398 pound-feet of torque. However, it should be remembered that this is still highly speculative.
As for the 2024 GMC Acadia, the overhauled third-gen crossover will grow in size compared to the preceding second-gen model, dropping in as a new full-sizer that takes the nameplate back to its first-gen roots. The 2024 GMC Acadia will also be more truck-like, and offer better execution of the off-road-oriented AT4 trim level.
As a reminder, the current GMC Acadia offers two engines, namely the turbocharged 2.0L I4 LSY gasoline engine, and the naturally aspirated 3.6L V6 LGX gasoline engine. The naturally aspirated 2.5L I4 LCV was offered previously as the base engine, but it was dropped for the 2022 model year.

Welp… that’s all she wrote for me with this vehicle. Thanks for the memories 2014 Acadia, you will not be replaced with the same.
They had three years to get this right by redesigning the vehicle to RWD and using the off-the-shelf L3B and 8-speed, not going out of their way to downsize the displacement. And do we REALLY think an uprated 9T65 transmission to handle the torque is going to be a long-lasting driveline? It’s leaps and bounds better than the 6T75, but these are the kind of decisions that get GM in trouble.
… and of course they’re going to be putting Z71 and AT4 badges on these things. What a joke.
Guess I’ll be going to the competition for my family-hauler/small trailer towing needs. The ONLY way they salvage this for me personally is if because of the lightweighting of the powerplant, these things come with 1,800 lbs payload/11,000 lbs GCVWR. At least that would offset some of the other considerations.
Same. Was looking forward to buying one but I won’t unless they have at least the 2.7L from the new Colorado.
I thought the Acadia was gonna be built to rival the x5 and cx9. Wtf we doing here? That 2.7 would’ve been perfect for this rig.
Why would they power this gargantuan vehicle with a turbo 4 cylinder? Mary doesn’t know what she’s doing and she needs to step down.
I agree with you.
Hopefully, the fuel MPG will be better than the 2.7 engine. I assume that is why they are engineering it.
Why is GM so averse to hybrids? I don’t get it!. Whats wrong with this engine and a hybrid version? They prefer to go from 100% ICE to full Electric!
An ICE engine is complicated, expensive to build. EV propulsion is also very complicated and expensive to build. Put the two together as a hybrid and it more complicated and expensive. ICE and Hybrids must meet strict EPA requirements, EV’s do not. A few years back an engineer responded to a comment that I made was correct.
The GM Volt Hybrid was a truly well made and engineered product. Owners just loved it, no recalls, no software bugs and reliable. I was at a Chevy dealer in 2012 and the salesman was hoping that the drivetrain would be put into the Equinox. Well it never happened because the cost for a hybrid system was just too expensive.
Tesla is slowly taking sales away from ICE vehicles. This is the trend. ICE vehicles will be around a long time and EV’s will not solve the world problems but it is going in the right direction.
Add to this the cost to develop the Hybrids that will also be around a limited time would also take money away from the EV and battery investment.
GM is going to keep small ICE engines alive as long as possible and then only go full EV when they have to. This is why we are getting versions of each.
To be honest based on what I know the Turbo 4 will move this vehicle just fine odds it will have 310 or very close HP with a bit less torque than the 2.7 as it will not be needed.
People just need to get over the fact that it is not the cylinder count but the output that makes a difference.
I used to be the same way till I had a2.0 turbo with 300 HP. It was faster than either big block car I owned and much more torque. It also got near 3 times the mpg.
More complicated, yes, but it’s a piss poor excuse considering Toyota, Honda and Ford all do a significant portion percentage of certain vehicles with hybrid systems.
Except Toyota seems to have no problems with the hybrid set up and makes oceans of money doing it.
DM That is what GM thought of the 2.7. that mpg would increase. Takes more fuel consumption to move a heavy load with a smaller engine than to use a bigger displacement engine. And I don’t think that by shortening the stroke on the 2.7 to a 2.5 is going to increase economy as the engine will struggle to move that monstrous vehicle along. But then again Mary will decide to use a new 0-0 oil to reduce friction. She is out to prove the Nay Sayers wrong by installing 4 bangers in every GM vehicle. Sort of like drinking a stronger beer in place of an ordinary six pack. It Don’t work.
What may be getting missed here is: what will it do on Uncle Sam’s Treadmill Test? That is all that counts; the real world take the hindmost.
So an engine so called upgrade is to make it smaller with turbo to run probably on premium gas, use oil,run hotter and not be durable.
You determine all of that from one article about a vehicle – and engine – that have yet to be released.
These are premium not required engines. GM is only Premium recommended on performance models or engines you install a tune on.
GM is sensitive to the average buyer refusing the few pennies more on gas.
GMC isn’t going to put a 4 banger into their version of the Traverse. Kind of screws with the Towing Capacity and messes with their “we are professional grade” slogan. Plus, you’ll never see a Chevy best a GMC. IF ITS GOT A 6, out goes my Grand Cherokee L…
They also put a 4 banger in a full size truck…
I’m on my 3rd Acadia but when GM made it smaller, I gave up. Now they’re making it bigger? Too late.. just ordered a tahoe premier.
That 2.5 will out perform the old 3.6 hands down with the big bump in torque and it will easily out perform the 6 in the Grand Cherokee. In a heavy vehicle like these, I want a healthy amount of torque down low to make towing, hauling and day to day driving better. Less down shifting and better mpg.
I would wait until making a statement like that. Look at the current new body style Colorado/Canyon that gained a lot of weight and switched from a 3.6 V6 to the mighty torque monster 2.7 only to have the old body V6 truck outperform not only in 0-60 times but also in highway fuel economy which sucks on the new trucks. If they can keep the weight in check and the new engine has a lot more torque then yes it should outperform the current 3.6
Well I was going to buy the new 2024 but now I won’t be. I would want at least the 2.7L from the Colorado/Canyon. This sucks…
Haha, this will be a big improvement over the 3.6 with all the torque it will offer. the 2.7 would be great but it is for RWD models, this 2.5 will be exactly what the doctor ordered. Don’t get stuck in old ways of thinking, they don’t apply these days…
Folks are really complaining like the performance figures have already been released. This is a fwd application of the 2.7 in my eyes and I’d expect power levels to be much higher than the 3.6 it replaces but just short of the 2.7 Most probably just need to buy a Tahoe if they want RWD and big power
The disappointment with drivetrain decisions continues (with the exception of the 3.0L duramax in the trucks, which frankly I’m still surprised they went ahead with given the overal idiotic nature of their drivetrain strategy).
I have a 2018 Terrain with the 1.6 Diesel, and what a beautiful vehicle to drive. Effortless torque, and unbelievable fuel mileage (I consistently get around 47 MPG highway). They really should downrate the 3.0 Duramax and offer it in the new fullsize crossovers.
Disappointed. Waited for the new Acadia only to have GM pull the engine switch. The current six cylinder, 310 HP is perfect for the new bigger model. Most GMC buyers are towing something and don’t mind the extra cost. If GM pulls the six cylinder I’ll be buying my first foreign vehicle since my Volkswagen in HS. Is GM seriously just trying to make their products less competitive??
Tell us you don’t know anything about cars without actually telling us. In a heavy vehicle and especially for towing you want torque (hence the love for the diesel in trucks). This new engine will probably land around 300hp with a big bump in torque which you really want. This will make it more competitive, better to drive, tow and save more on gas. Cylinder count does not equal anything these days especially a title. They put a turb 4 in their full size trucks and reviews well, it will be fantastic in this new set up. Would be nice if they had some other higher options or a hybrid, but this motor will be improved on over the 3.6. Reliability will not be of concern.
The 2.7 L3B engine was designed as a truck engine for the Silverado but many still cannot get their head wrapped around a 4 cylinder on a full size truck. So with some tweaking it’s a perfect fit for the Colorado with three different tunes.
However, because of turbo technology and DFI, manufacturers no longer sell displacement or cylinders but only HP and Torque. Until you drive a turbo engine you can’t knock a four banger. It is not for every application, probably not but manufacturers have to look at the whole picture. If more is needed there are full size trucks.
No 6 cylinder, then no purchase. head to Ford
We have the 3.6 in an Impala, Terrain, Canyon & Acadia, and it has served us well and reliably in every application- all over 100,000 mi with no issues. If I can’t get a 3.6 in a 2024 Acadia, I won’t be buying a 2024 Acadia.
I LOVE the color midnight blue metallic! I currently lease a 2021 Acadia and was sad to learn the color was discontinued. I was planning on leasing the 2024 Acadia in the same color 😭 the new colors are crappy so not sure I will stay at GMC.
The Volvo XC-90 uses a turbocharged 4 cylinder engine and a turbocharged,supercharged 4 cylinder engine. 250-316 hp respectfully. They are AWD models that will pull up to 5000lbs. Based on the Volvo the 2.5 Turbo may be a good fit?
It’s bad enough We have to eventually say good bye to the The 5.3 best engine (still going in my 2002)which is a long hauler with low RPMs on tach dosent work hard.Remember those commercials about viscosity break down of oil I guess that doesn’t apply to these little four bangers with ten speed transmissions,We are being sold engines that might make 100k without somekind of service ,turbo included.Most people lease could care less about 5yrs down the road.Currently have a Enclave with 3.6 can’t see going up hills while engine is screaming looking for the right gear in keep lower revs and keep up with traffic 4cyl isn’t the answer.At Least offer a 3.6L as option it is a good engine for us car owners.I will pay more for it as long as it comes with badging on fenders lol.Remember GM is trying to keep up with new energy standards in up coming years,Get your 3.6s before their gone like the V8…
We were seriously considering a 2024 Acadia Denali but after learning about GMs ridiculous decision to drop the V6 we will most definitely be dropping our decision to buy one Once again GM has not failed to dissapoint
