I have 500 miles on my new 2025 honda civic hybrid sport touring. I drive mainly highway. I do drive 7 to 8 miles over the speed limit on cruise control. I don’t drive aggressively and there is some hills, but I’m only getting 38 miles per gallon instead of 48 miles per gallon.
So not sure if the 7 or 8 miles over the speed limit would reduce the mpg by 10. That’s a little far fetched. If so they should state that in there mpg add. Please give me better news than what I’m seeing so far on my dash? Thanks
I also drive to work in a snow belt area. I have never had low profile tires and wonder about driving with these tires in snow and ice roads
 
hi I purchased my 2025 civic hybrid sport hatchback touring in March., currently on a trip from Halifax Nova Scotia Canada to Newfoundland Can. So far have put close to 2000 km on the vehicle. I am recording my mileage and gas consumption- so far it appears to be doing well…average 4.8 litres per 100 km. I‘m pleased with that.
Things im not so happy with is (1) the cabin road noise… i expected better. (2) No spare tire - so I prepared and purchased a spare wheel and tire - hard to get, which is stored behind the driver seat. The goop / slime with an air pump is just silly. (3) no jack or wheel wrench is ???. (4) a few other irritating issues. I know it’s a good vehicle but………
Happy travels

Note that the hybrid civic does not get much better mileage on the highway than the gas only Civic. If most of your driving is highway, you will not see much difference between your previous car and the hybrid.
I disagree if you keep speed at 65 mpg. I just traveled RT to Phoenix from Tucson AC all the way Cruise on 65mpg and average for trip was 54
 
I recently bought a Honda Civic Sport Hybrid Hatchback, but I’m experiencing poor gas mileage. I’m not sure if there’s a break-in period or procedure I need to follow, but the car isn’t giving me the fuel efficiency I expected. For comparison, my 2016 Honda Civic averages around 33-34 MPG, and the hybrid isn’t performing noticeably better.

I’m unsure if I’m doing something wrong or if there’s an issue with the car itself, but it’s frustrating. I’m considering taking it back to the dealer to figure out what’s going on.

Has anyone else experienced something similar or know why this might be happening? Any advice would be appreciated before I take it in for service. Thank you! View attachment 23581
For me the driving style makes all the difference. Very slow acceleration out of stops can make a huge difference. I'm consistently getting around 45 mpg in city and some days more and I'm running AC continuously.

I actually get anywhere from 46 to 43 mpg on the thruway. Sorry but I don’t drive like a grandpa. I drive 65 miles to work and 65 back home. I set cruise at 73mph. I say it’s not bad. Im not a speed demon by no means. I’m actually saving a lot on gas. I don’t always drive thruway home. Back roads I get 48 to 49 mpg. I had just gotten the car when I posted this. So overall I’m very pleased with the civic Hybrid. Only thing now is the #3 piston went with only 12,500 miles. Have to get a brand new engine now. Hopefully no other issues after that🤞🏻🤞🏻🤞🏻🙏🏻🙏🏻🙏🏻
 
There's alot of factors that contribute to mpg. Top three is weather temperarure, driving habit, and tire pressure/wheel alignment. If you drive it with the ICE always on (maintenance mode) expect 28-32mpg. In normal conditions 47-50mpg.

I'm a gearhead that does alot of WOT and spirited driving. Currently the fastest civic hybrid 14.4s and still get 50mpg.
 
Out of curiosity, I did a test. 2023 Civic eHEV Advance (european hatchback hybrid).

Starting and finishing at the same highway rest area, going up and down a highway. 90% highway, 10% highway junctions. Doing 5 runs at different speeds on the same road circuit.

Fair weather, no wind, 16°C / 60°F outside air temperature, 20°C / 68°F road temperature, 45.5 km / 28.3 mile distance, 273m / 896 ft of elevation gain and loss. Road was empty, apart from junctions and start/stop I was travelling at cruise control speed.

These data look great - thank You !

Focusing in the English system measurements, I was surprised that at 75 mph the electric drive was still occasionally on.

And the mpg numbers are encouraging. My gas powered FIT only gets around 36 mpg at 75 mph. And of course the hybrid does nothing but get much better at lower speeds.

It’ll do up to 80mph depending on battery charge level. I’m at 50.1mpg now.
 
Thanks for your feedback on the road noise. I've been asking about this on the forum and not many responses either pro or con. To me, that is a bigger issue than lack of spare tire, which is annoying but more obvious.
Lack of a spare tire is a lot more of a concern depending on where you live and drive. You won't realize that until you get a flat at the worse time, in the wrong place, in lousy weather. Not down playing the road noise issue- I am very very disappointed with the road noise infiltration into the cabin - I have a 2025 civic touring hybrid sport hatchback. With the Bose 12 speaker audio. Might as well have a transistor radio. Trying to be positive but.
