This post here confirms all my observations. I'm at 2000 miles and hitting 38.9 mpg. My best hwy mpg has been 38 mpg, well below 47 hwy mpg as advertised. The recharge behaviors cruising the highway is the same. That baffles me.

I'm in Wisconsin, a much colder environment than others have been reporting. A lot of details have been shared by others such as the cold and winter blends and what not. But I can't believe they have that much impact when the 2014 Corolla ECO that I traded in achieved 43 to 47 mpg hwy most of its life. (2014 Corolla ECO advertised mpg was 42.) No one can convince me that 38 mpg hwy is acceptable for a vehicle advertised at 49 hwy.

Our Civic Hybrid was expected to be an mpg improvement, but feels like it was a lateral move or a step back. I really want this to work out.

I love this car. It's style, size, power, how quiet it is. I want it to achieve what was advertised. My wife and I have discussed trading it in on a Corolla Hybrid. We have a long history with Corollas.

Conditions definitely affect the mileage. I just drove about 25 miles on secondary roads at a maximum of 50 mph and I got 63 mpg. On a long highway run at 80 mph, I get about 45 mpg. On a cold morning I get about 38 mpg. The government mileage estimate is under very specific conditions and should not be taken as the daily expected mpg unless you drive under those same conditions. For me, the fuel economy is great, but I bought this car for the comfort, power, and handling as well.

Toyota does hybrids better than anyone. That said you’ll lose more on the trade than you will ever make up in fuel economy.

Corolla's interior is blahhh comparing to Civic. I would Never get Corolla just for gas mileage.
I would not mind Prius Prime (as price is identical or close to Prius non-prime due to feds rebate) but I am NOT paying monthly subscription for navigation Toyota is asking for. What a DUMB move... cloud BS.

Stay with Civic; mileage will improve over time. You cannot expect 'fantastic' mileage after few thousands miles plus driving at high speed in winter. Duh...

The Civic is also a bigger car with an attractive stance on the road. The Corolla is a better buy but looks more economy car on the road. Let’s face it looks count even more in this segment, you don’t want to look like your driving an economy car if it can be helped.

As cars get more efficient, the variations in fuel economy becomes larger. Each use case outside of the norm has much greater mpg impact. (and mpg is a terrible metric.. but thats a topic for another day).

For example, you’ll notice the mpg impact of adding a roof rack to your civic much more than a suburban.

No one mentioned if they were driving mostly in normal, eco or sport mode. Shouldn't that effect the mpg?

First 1,000 miles was ECO mode. Following information from many fine people like you, I have switched and stayed in Normal mode. Did it make an mpg difference? Can't tell. It does feel better accelerating, however.

You know what is kind of funny? 0 to 60 in a Civic is 6ish seconds. That's about as fast as my 75 Mustang with a modded 302 V8. :)

There are a couple of differences. In SPORT mode your regen will not auto-reset but will remain at the level you set with the paddles. This is useful on winding mountain roads as it mimics driving a manual in a lower gear. In ECON mode it will lower the effectiveness of you A/C so you won't want to use it on a hot day. After four months and about 7,000 miles I mostly never look at the mode switch other than occasionally using SPORT mode for the above mentioned reason.

1,11 miles in. A road trip of 600 miles returned an average mileage of 38. Not happy with that either. My 22 turbo got 44 on the way. It has an EVAP code. Going in to be serviced. Will mention the milage concerns with the dealer. Does anyone notice an increase in mileage after a break-in period?

Same here after 1,100 miles. Struggling to get 38mpg.

I'm struggling too - to understand how so many people are experiencing this. At just over 7,000 miles my life average is still at 48.9 mpg. Granted I have had no winter and all of it has been solo so no passengers but honestly I would have to keep it in SPORT mode and drive it like I stole it to get down to 38 mpg. There must be some underlying cause because you are not the only one reporting these sort of results. I'm guessing it's cold winter weather perhaps combined with seasonal fuel blends for the area you are in. I'm in California with many hills and mountains so I don't think terrain has any real effect, what you lose going up you gain coming back down. I've also done many highway miles though I've not really done much over 85 mph if at all.

I'd be interested to hear what long term results show. If you never reset the Trip B meter you can use it to get a more realistic estimate. These results reported after only a couple of hundred miles could be all over the map.

I would say most of the difference comes down to conditions (cold weather) and the variance of that people call 'highway' driving.

Scenario 1 (worst case): 'Highway' driving at steady state/continuously at 75mph for 3 hours, at 35f temp. I would get something like 38mpg in this instance.

Scenario 2: 'Highway' driving a commute to work which might have the majority highway, and is a 20 minute trip. Even 15% of non-highway during a 'highway' trip can make a noticeable difference to the average mpg if the trip is only 20 minutes long. I would get something like 41mpg in this instance assuming conditions equal to scenario 1 (75mph, 35f).

Scenario 3 (best case): 'Highway' driving could mean driving on the highways in/around a city where traffic/speeds change between 55-70mph and the temerature is 70f, with 15% as 'city' driving getting to/from the highway. In this ideal 'highway' trip scenario I would get probably close to 50mpg by my estimations/experience.

In my experience so far (~3,500 miles) I think anywhere between ~37-50mpg is a realistic average for 'highway' driving, with the variance largely depending on speed, temperature, and the type of 'highway' driving you do. Terrain (hils/mountains) could also make a difference, but I cannot comment on that, as so far I have been driving mostly in fairly flat areas.

I live near NYC, currently at 4,000 miles,
43.949 lifetime avg
34.828 last tank (multiple remote starts with the heat cranked, mix of driving.. highway stop and go commute, highway normal speed,l ocal back roads)
usually keep it economy, but lately i've been putting into normal, and making use of the paddle "shifter" to use regenerative breaking when possible.

I haven't seen over 40mpg since my 12/1/25 fill up, so gas used at the end of November. I think weather plays a huge factor, and it'll be interesting to see the yearly MPG averages. A lot of North America will also have enough heat come summertime we'll be running the AC in the car using up precious energy to cool the car, so i'm not so sure it'll be better then winter time MPG., leaving just the fall and spring for people to get the advertised MPG, and the winter and summer dragging the overall down.

I'm at just under 7k miles with lifetime average reading 48.8 mpg mostly very warm, including a trip to Las Vegas and back with A/C always on and have pretty much never used ECON mode. Prior to the onset of "winter" which here in California means dropping down to a bone chilling 40 deg F the average was 48.9 so using heat definitely hits harder than A/C.

Where are you getting the MPG ratings you are quoting? From the trip computer? Or are you actually hand calculating?

I just had a ~250 mile fill-up where the trip computer claimed low 40's. Actual MPG was only 38.

I've done both and found the results close. If you are going to manually calculate you need to do it over multiple fill ups because different pumps at different temperatures and barometric pressures will shut off at different levels so you are not necessarily getting a more accurate result going on a single fill. Also you need to be patient and get a long term average, give it time.
