Horrible gas mileage in brand new CX-5

[Mike2000z28]

Hi guys, I recently leased a brand new 2025 cx5 GT with 64km on the clock. I got it with a full tank of gas and it has around 204km on it now at pretty much a half of tank.

I literally have a 4km commute to work pure city stop and go, and im driving like a grandmom because I still can't believe the mileage. Im getting around 15L/100 with granny driving.

Keep in mind this is warmer temps and I live in Canada. I used to have a 2008 cx9 GT Awd that got similar mileage but that was expected for that truck. If it doesn't change im going to have to give it back. I was expecting 4 cylinder gas mileage of mid 20smpg, not 16mpg.

Has anyone else this issue with a fresh brand new cx5 with the 2.5 NA?

I could see this mileage being possible with short commutes and city driving. If you took the car for a 5-10 minute drive down the highway, your mileage for that drive would be much better.

I always like to take a new car on some longer cruises, if possible. Especially on the highway for an hour or two.

I should note, though - a highway drive may not be a good idea with such a new car. Since the car is still in it's "break-in" period, you don't want to be cruising along at the same engine RPM for an extended period of time. Usually this means no road trips or long drives. I think a 5-10 min drive would be fine, but to be on the safe side, you'd want to vary the engine RPMs often, and let the engine get up to normal operating temps instead of driving it "cold" often, based on what the owner's manual recommends for new cars.

That's the issue as well as the car doesn't get to operating temp I think. What should the thermostat reading be at full operating temp? 100 degrees celsius?

Cold engine = below rated mileage

Stop and go = very inefficient

I think you would benefit from a hybrid.

Normal operating temp is about 90c. Right in the middle of the temp gauge.

Yeah, but cmon city mileage is city mileage. It's short trips and stop and go. 15l per 100km is to much of a difference. My cx9 was older and got the advertised mileage for the most part.
