2025 GMC Terrain Gets Slightly Better Fuel Economy Over 2024 Model

The 2025 GMC Terrain is poised to usher in the crossover’s latest third generation, complete with a long list of changes, updates, and upgrades. Although the 2025 Terrain has yet to make its formal introduction, GM Authority has already uncovered fuel economy ratings for the new Terrain. Interestingly, the 2025 Terrain offers slightly better fuel economy when compared to the 2024 model year.

The front end of the next-gen 2025 GMC Terrain.

The insights were provided via Natural Resources Canada (NRCan), which has already released fuel economy ratings for the 2025 GMC Terrain. NRCan typically posts the same fuel economy estimates as the EPA. According to NRCan, the 2025 Terrain returns slightly better fuel economy in several driving conditions when compared to the 2024 model.

More specifically, units of the 2025 GMC Terrain equipped with front-wheel drive provide an extra 2 mpg in the city and an extra 1 mpg combined when compared to estimates for equivalent 2024-model-year vehicles, while units of the 2025 Terrain equipped with all-wheel drive provide an extra 1 mpg in the city.

The NRCan fuel economy figures were converted from L/100km to mpg, then compared to mpg figures for the 2024 GMC Terrain, which were provided by the EPA. Check out the table below for a full breakdown of the 2025 GMC Terrain fuel economy estimates:

2025 GMC Terrain Fuel Economy Ratings vs 2024 GMC Terrain
Model Engine Drivetrain Driving Type 2025 MY L/100 KM 2025 MY MPG Equivalent 2024 MY MPG + / – 2024
Terrain Turbo 1.5L I4 LSD FWD City 9.2 26 24 +2
Highway 8.3 28 29 -1
Combined 8.8 27 26 +1
Terrain Turbo 1.5L I4 LSD AWD City 10 24 23 +1
Highway 8.4 28 28 -
Combined 9.3 25 25 -

Notably, the 2025 Terrain once again cradles turbocharged 1.5L I4 LSD gasoline engine, but introduces a few significant changes to the drivetrain. Front-wheel-drive models will now utilize a continuously variable transmission (CVT), with peak torque now rated at 184 pound-feet at 2,000 rpm. All-wheel-drive models will feature GM’s eight-speed automatic transmission, with peak torque rated at 203 pound-feet of torque at 2,000 rpm. The 2024 GMC Terrain was equipped exclusively with the GM nine-speed automatic transmission.

In addition to slightly improved fuel efficiency, the 2025 GMC Terrain also introduces significant design and interior changes. The overhauled interior takes cues from the 2024 GMC Acadia, providing a more modern and refined cabin experience, while the exterior design was tweaked to follow the latest GMC design language.

Production of the 2025 GMC Terrain will take place at the GM San Luis Potosí plant in Mexico, with production expected to kick off in October.

  1. Wait for the US numbers! Jeez, Louise. Folks will read this and assume the US numbers will be the same. In any event, these numbers, like the Equinoxes, are pretty bad.

    1. The test method is the exact same. Look at the results from previous years and this should be obvious. I am sure that GM just does 1 test and submits the same results to each country.

  2. They need to add the 2.0L motor. This 1.5L is too stressed for this size of vehicle. The 1.5L belongs in the Trailblazer and the now older Trax model

    1. You opinion defeats the purpose of planned obsolescence my friend.

  3. As a GM buyer for 60 years I am appalled with this GM trend to 4 cylinder motors of less than 2 liters. I owned a 2016 terrain with 2 liter 4 cylinder which performance and gas mileage was just adequate. My Terrain replacement is a 2019 Tiguan with 4 cylinder 2 liter with turbo which is a slight notch above the Terrain.

    In 2016 GM also offered a v6 in Terrain but was out of my price range at time. In 2019 I was ready for a new Terrain but GM had dropped the 6 cylinder – what a disappointment, but my disappointment was only beginning. In 2019 GM was only pushing a smaller turbo 4 cylinder 1.5(?) liter which I test drove and it was pathetic as This version was always “on boost”, due to the lack of cubic inches, just keep up with city traffic and they moved the gears selector to the dash which took away the Terrains sportiness of the previous console gear selector of 2016. Some styling cues were made to rear quarter panels that made rear vision more difficult. Stylistic changes are not always good!

    These GM turbo 4 cylinders of less than 2 liters are just boat anchors and I will not return to GM family until they get this anemic 4 cylinder motor theme out of their system. Worse yet they are placing the same motor in an Acadia. What is next a 1.5 liter 4 cylinder Corvette? These motors are a bad joke.

    For $36-$48k I want something sportier than a skate board with a anemic 4 cylinder motor.

    1. Jim, where to begin. First, that motor is NOT in the Acadia, the 2.5 based on the Silverado 2.7 is in there and has been reviewing well.

      Second, come back to the new school way that your outdated way of thinking replaces. I love a big displacement, but a smaller turbo motor drives so much better then a NA motor of similar HP as it lacks TQ. Give me a 1.5 making 190hp/220tq over a 2.5 NA giving 200hp/170tq any day.

      I just rented a 1.5 Equinox in Nashville a few weeks back, specifically picked it out as I wanted to get a refresher on the motor. Wow, some of things people (such as your self) say shows two things, A, they haven’t driven that motor and/or B, they completely miss the demographic of this class of vehicle. The 1.5 is towards the top in terms of all around behavior. With all the torque it is nice to drive around town and cruise down the highway. It wasn’t needing to downshift or rev at a slight hill or merge and keep up with traffic. The only place it could have used another 15-20hp was foot to the floor highway speeds which lets be honest, 0.005% of the people who shop this class are needing or trying to use.

      It is a great little motor, not sure all the hate on it here. Well, honestly I do, it is some so called older car guys that think everything should run 0-60 in under 6 seconds and cubic inches determine all. That is not the case. That equinox would run to 60 in the mid 8’s and got nearly 30mpg in my hands for the long weekend. Nothing super special but a good little car that was comfortable, quiet and adequate with power, which is exactly the class of person that drives these. With variable van turbos power is nicely spread out. The 2.0 a few on here hold to some pedestal didn’t sell. The coming Hybrid will help with the optional more powerful engine which most of the competitors have as their option, not many offer big gas turbo motors as an option and all their standard motors are on par with the GM twins.

      Nice ramble there Jim, next time do a little homework on the class and buyer and spend a little time in one without thinking it should have Camaro power, atleast you will have a little more of a honest review then…

      1. Turbo’s introduce dangerous lag.. I’ve owned a couple turbo’s, never again. They cause accidents as the lags for split second while waiting to get through intersections. EVERY turbo has lag, and they are even more pronounced on these baby 4-cyl engines. Punch it and wait, and hope that 1-2 seconds of stalling doesn’t get you hurt. Torque doens’t matter if you have to wait on it.

        Reply
        1. Most are done correctly today and there more low end torque to avoid the lag.

          You will need a new excuse.

          My last 2.0 Turbo has so much low end it would spin the tires rolling at speed,

          Reply
          1. not at all.. they all still have a lag. Eventually there is great torque.. There is no turbo to match the instant feel of na engine. That second can be necessary for safety. I have been in too many intersections with an XT4 & 5 that had turbos. Each had a hesitation. Modern schmodern, it still needs to wind up. Sometimes you have a small window, and I don’t want to be caught waiting.

      2. Stop spreading disinformation about the 2.0T. They didn’t sell well in 2021 when GM severely cut back production on this engine and forced more 1.5t’s on the market and then dropped it in 2022. There are a ton of 2018-2020 Equinox’s and Terrains with 2.0T engines. We see them all over the place, at the auctions, car dealers and on the road. They did sell when GM offered them and so many of our customers ask why they can’t get this engine anymore especially on the pricier SLT and Denali trims of the GMC! Dialing back production and claiming an engine didn’t sell is false and misleading especially when it was to satisfy an agenda to lower production costs by streamlining.

    2. … my 2017 Terrain Fwd 2.4 gets better fuel economy. I regularly see 32-34mpg on highway

      This isn’t an improvement.

      Reply
      1. Couple of my family members have the 1.5L equinox and terrain. They regularly see over 32 mpg WITH the AWD. And the best I’ve seen is 40 mpg. We had the 2.4L in the past and i would rather take the 1.5L any day. The torque is so much better.

    3. Jim… You’re obviously having a Brandon moment.

      Here’s some assistance for you.

      The 2016 GMC Terrain had two engine options: a 2.4-liter four-cylinder engine and a 3.6-liter V6 engine:

      2.4-liter four-cylinder engine
      The standard engine, which produces 182 horsepower and 172 pound-feet of torque at 4,900 RPM.

      If you had ‘weak power’ in a 2.0, you must have pulled a plug wire loose….

  4. A disposable CVT in a GMC. Wow. -How low can one go!

    Reply
  5. This and the Equinox are the same basic vehicle correct? So how is it the Nox has gotten a little worse and this is just a little better? What gives?

    BTW, although I’m not an SUV buyer, that white one in the picture that is fully painted is the nicest looking of them all.

    1. The 6-spd in this year’s Nox is more efficient .

  6. The Angry Mustache Grill is a deal breaker.

  7. Just think how far General Motors has gone in the last 20 years. Your car now requires three 1.5 liter engines to get what was then standard equipment. And throw in a CVT instead of a transmission to make it feel like your 40K is getting flushed down the toilet.

  8. I have a thought I’d like to get out to everyone…I’ve owned a few GMC Terrain’s over the years, my latest is a 2023 Denali, and it comes with 4wd whether you want it or not, here in So.Cal. I really don’t need it, but have to pay extra for it, go figure, why am I stuck with an option that I don’t want ot need, let me save a few thousand dollars, seems simple enough.
    My contention is simple, if GMC is serious about building “Professional Grade” vehicles (whatever that means) then please take a closeer look at your competetion in each segment you’re competing with then not only match the top seller and most highly rated vehicle in each segment but exceed in every area possible! What’s my point? Simply this…”stop building vehicles that are basically just Good Enough”, go to the next higher level, exceed you’re competitiors in overall design, in interior room, in top of the line interior materials, and yes, offer more than just one “acceptable” powertrain combination for the masses”. While the Terrain’s 1.5 liter 4 cylinder is “meh, okay” it has it’s limits and when driven in heavy city traffic or at moderate highway speeds, it is getting the job done…but life isn’t all just traveling at moderate speeds in city traffic, sometimes there are those of us who’d appreciate perhaps a 2 to 2.5 liter turbo engine in excess of 200 to 250 horsepower in this (for me) perfect sized SUV…I don’t need a bigger vehicle, the style and over all size is perfect for me. The secret to success, giving the customers what they want, by making options available that suit those potential customers needs and competing directly with others in this same segment of the market. If your competitors can do it GMC, then the only reasons for you not offering a direct competing drivetrain ect. is either plain laziness or a sincere lack of an understanding of what it takes to become a “top tier leader” in that segment of the market you’re competing in. If you continue to build vehicles that are “just good enough” and or “just adequate” (in power and other areas) you’ll never obtain the sales and repeat customer buyers that you’ll need to sustain your profit margins. Just good enough is never…good enough. Period.

  9. What Rick said!! I’ll just add I used to drive an Aztek with similar power numbers to the 1.5L, about 185/205 if I recall. The engine was great around town and up to about 60. After that it would “run out of breath”. When we go on road trips we travel over freeway passes that are 5-7% grades for 5-7 miles. The engine could maintain 65, but not without working really hard. If you have to slow down for a truck passing a slower truck getting back up to speed is a tall order. Compare this to our Terrain with the 2.0L or our Saab 9-3 with the turbo V6 (both about 250/250 in hp/ft-lb) and they fly up the hills with no problem. Passing on 2 lane highways when necessary is a lot less dramatic too.

    I’ll just add that our household thinks of it as a safety issue. To me it’s no different than wanting AWD for the snow. It doesn’t snow all the time where we live but I sure want the feature when it does. Like a better engine it also costs more $$ and sacrifices some mpg, but I want it and am willing to pay for it.

    1. Look GM is in a box. THey are a division that has to sell a cooperate platforms and engines while still meeting ultra high CAFe ratings and still keeping the price below Cadillac. Not easy.

      I know everyone has their specific own little wants and needs but the days of meeting them all are over.

      Today while some may offer appealing packages they make what you touch feel good but the bits under the skin are crap. That is why Hyundai has issues like bad engines and suspension issues.

      In this day and age of all models are over priced it is hard to package 3 models under the same brand. But GMC makes butt loads of money so it is what it is.

  10. Pretty sad that a tiny 1.5T can only muster 28 highway MPG with either the FWD or AWD model which shockingly is what the far more powerful 2.0T got with AWD in 2018-2021 or 29 with AWD! The city figures are up slightly but what is GM’s issue with highway numbers? They keep dropping as time goes on yet other companies with these types of vehicles are well over 30 for the highway. These numbers put GM on the bottom
