Here Are The 2025 Buick Enclave Fuel Economy Ratings

Earlier this year, GM Authority reported that Canadian fuel economy ratings for the all-new Enclave showed some improvements over the preceding generation. With that in mind, the Environmental Protection Agency has released its fuel economy figures for the 2025 Buick Enclave, and the numbers paint a similar story.

2025 Enclave units equipped with a front-wheel drivetrain are rated at a combined 23 mpg, while AWD examples are rated at a combined 21 mpg.

2025 Enclave FWD 2025 Enclave AWD 2024 Enclave FWD 2024 Enclave AWD
Engine Turbo 2.5L I4 LK0 Turbo 2.5L I4 LK0 3.6L V6 LFY 3.6L V6 LFY
Transmission 8-speed auto 8-speed auto 9-speed auto 9-speed auto
EPA city/highway/combined ratings (mpg) 20 / 27 / 23 19 / 24 / 21 18 / 26 / 21 17 / 25 / 20

Meanwhile, 2024 Buick Enclave units with FWD were rated at a combined 21 mpg, while AWD units were rated at a combined 20 mpg. Looking over all the fuel economy ratings as a whole, the 2025 Enclave is notably more efficient compared to the preceding generation.

As a reminder, the 2025 Buick Enclave’s online configurator is currently live and ready for exploring. Prospective buyers have the ability to choose between one of three trim levels – including Preferred, Sport Touring (ST), and Avenir – and shuffle through all the available options and features. Notably, each trim is offered with its own unique set of finishes, wheels, and colorways.

In regard to the powertrain, the turbocharged 2.5L I4 LK0 gasoline engine, rated at 328 horsepower and 326 pound-feet of torque, is equipped as standard throughout the entire model range, and is matched to the GM eight-speed automatic transmission. This output is directed to the front wheels, or all four wheels as an option.

Under the body panels, the next-gen Enclave is underpinned by the long-wheelbase version of the GM C1 platform. Production takes place at the GM Lansing Delta Township plant in Michigan, with the first units arriving on dealership lots just last month. Pricing starts at $46,395.

  1. I’ll take the 3.6L back, please. Knew this was coming. Not enough of an improvement to justify the new 4-banger.

    1. Huh? If gives you 20 more HP, 60 more TQ and an improvement in MPG? You do know the further we get in the ICE vehicles the hard the returns are getting right? You weren’t going to get an 8mpg improvement. Some people are just so entitled and have zero clue. I will gladly take a bump in mpg with a big bump in power. This 2.5 looks to be over built like the 2.7 so should last as long or more likely longer than the 3.6. So wins across the board, but beachy for some reason is not happy. Good thing GM doesn’t listen to you on how to run a company…

      1. We’ll have to wait for actual timed acceleration runs to know if the new engine is actually quicker but from several online reviewers it looks like this new engine doesn’t improve performance compared to the outgoing 3.6 and has a notably worse soundtrack. I’ll also bet real world fuel economy is barely different but that remains to be seen

    2. Beachy, then you’ll just have to go buy a 2024 (or before) Enclave.

    3. Exactly, hey GM how about a Small Block V8 or V6 that sips fuel, Figure it Out!! Most of us are not fans of the Beefed Up Noisy 4cyl that is Not Getting any Significant Improvement on fuel. I have a 355hp 2001 V8 LS1 Corvette that gets better Mpg on road trips
      In 6th gear OD!!

      1. That thing weighs 3200 lbs with a tiny frontal area and low drag, duh…. Plus it only has 25more hp than this motor, Wow!!!!

  2. My how we have made such progress backwards.

    Pathetic numbers when you consider large Buick sedans from 30 years ago were getting that or higher. Welcome to the age of big, fat, ugly and over-weight SUV’s.

    I’m sure glad that it’s not me paying the gas bills on these things.

    1. Just for fun:

      1996 Buick Roadmaster with the detuned Corvette V8. Rated MPG of 15 city, 24 highway and 18 combined. That was a huge sedan with a monster V8 and not much different from this Enclave AWD no matter if 4 or 6 cyl.

      Now 1994 Park Ave: 17/25/20. The difference though is that the RM and PA would consistently do better than the ratings. This is through my personal experience as well as reported MPG from many customers over the years. This box Enclave? I’m willing to bet they will struggle to hit the rated MPG. Once again, going back to my experiences and personal testimony from customers is that the Enclaves have never gotten the MPG they were rated at.

      1. If people keep driving over the speed limit of course they will never match the Rated MPG.

        1. @HAHA: Doing over the speed limit certainly does affect the MPG, but when you are also doing that in a cement block design that is over-weight and ugly to boot, the MPG’s will never be good. This SUV/CUV craze is negatively affecting everything around us on a daily basis just so overweight people can ride around in their tall fat gas hogs.

          On the flip side, you could drive that RM or PA from many years ago at a constant 70 miles per hour and exceed the ratings all day long. Try that in these boxes.

      2. cim88,

        Let’s do some math here. It averages 3mpg less, with 70 less HP and better aero dynamics (it is only 60 inches tall), yeah, good thing we didn’t stay in those dated ways.

        Funny, my personal experiences are Enclaves exceed their MPG ratings. See how the internet works?

        You have a full size CUV weighing 2.5 tons able to out accelerate, hold more, tow more, get better mpg with a ton more room inside, but people still complain? This new motor is more powerful and gets better mpg yet people still complain. You just can’t win. They don’t want EV’s, here is a nice new powerful ICE motor for you that meets emission standards for the next X years so you can have ICE, but you’re going to complain. GM could have made a motor with 260HP and 330 ftlbs and gotten another 5mpg but you all would have complained about not enough power like that old roadmaster was.

        1. TMI: Your comment is difficult to follow, but I’ll try.

          First part I don’t understand at all.

          Your personal experience? And then you say the internet? Contradiction anyone? So MY personal experience was selling them starting back in 2008 with the first ones. I sold both Buick and GMC, so we had the Acadia and Enclave. Not a single one could pull anything over the rated numbers (unlike the older Buick cars) and nearly every customer I got feedback from would tell me their real world driving MPG. It wasn’t pretty. Most were consistently in the high teens. Real world from real drivers. Not the internet.

          Not everyone wants a “full sized CUV (SUV) that comes in at 5,000 lbs. Hold more? Tow more? Ya, that once or twice a year when they needs to haul some large box that they could have had delivered cheap or for free. So drive these big fat gas hogs all year for that? And no, they don’t get better MPG than the older cars.

          If they want to win, then they need to start building cars that buyers actually want. Take the entire Buick lineup today and combined they sell about the same as just the Malibu alone. And, if GM actually cared about the Malibu and promoted/advertised it, the Malibu would blow every single SUV that GM sells out of the water and come close to the two highest selling CUV’s. But hey, go ahead and keep pushing these fat gas hogs. Your children and grandchildren will benefit from it when they can no longer go outside due to heat and climate problems. But at least you got to keep driving your SUV’s.

          1. Very Simple, give the Buyers Options! I Personally Expect Options for a 50k plus Vehical Purchase, it’s just that Simple!!

  3. If they had a hybrid you could have similar power and torque but also have 35mpg combined.

  4. I’ll also keep my 2023 V6 it’s smooth running and gets average 20 mpg and up to 28 on road trips, I’ve even had up to 30mpg!! Hey GM Stop reinventing the wheel improve what you already have, give the Customers Engine Options!
