Two comments for the OP:

1. You can change a setting in the settings menus, to have either the trip A or trip B odometer automatically reset when the gas tank is filled. This is handy if you are recording odometer miles and actual gas purchased, to manually compute mpg for each tankful of gas. Of course, you still need to record the data....

2. Most Accord Hybrid owners seem to report that "actual" mpg (computed from the odometer readings and actual gas purchases) is better than what the car reports. This is the opposite of most cars, when tend to report mpg that is a bit better than actual. In my case, the car's calculation is typically 2-3 mpg worse, than a manual calculation, and sometimes the discrepancy is even larger. I suppose I should be happy that the reality is better than what the car says. But I find it to be "psychologically" annoying.....

I find it to be a nice surprise.

by the way, while at a closed track recently I ran the car at full speed for many miles. Reset mpg meter and got 21. Wow - that’s actually pretty good as that’s as bad as you can get in mpg with foot to floor in sport mode going all out. Interesting....

Yeah, the first time I flipped over to sport mode and went for a floor stomping ride (woke up five minutes before my work shift started) by 17 mile trip yielded 31. Granted a fair amount of that was sub 60 on the interstate in traffic so that helped out. Was still impressive that stomping it returned better than nursing my other car.

Just joined with a 2020 EX-L trim. I upgraded from a 17' Civic EX-T MT. Was a fun car to drive and keep, but my regular 75mile-one-way commute to NYC really asks a quieter ride with more safety/convenience features.

The fuel economy is fabulous! On highway at 70-75 mph it manages to reach 45+ mpg, beating Civic at roughly 40 mpg. The city mpg is also fantastic, I can easily hit 50+mpg vs below 30mpg for the Civic.

It is really engineering apex.

I have a 2019 EX-L I bough new last October. I currently have 15K miles.
I'm extremely impressed with the fuel economy on this car. I've managed to average 50mpg during Chicago winter with winter tires on. I also have a spare tire in the trunk.
Since it warmed up a bit, I've been getting 60+mpg the last 4K miles (about 7 tank fill ups). My personal best tank for was 63.3 mpg (filled up at 676.4 miles with 10.68 gallons) and best range was 701 miles on a different tank which yielded 60.6mpg. My first oil change came around 11K, at which time I put on the stock tires back on, so not sure how much this contributed to the overall improvement in the fuel economy. My suspicion is that the ambient temperature is by far the biggest factor as I noticed huge variance in mpg on individual drives on cooler days. The tires run about 36 psi.
My drives are about 80% open roads with 35-55mph speed limits and 20% Hwy going 70mph, depending on the drive. I think I can beat my record if I try and don't drive on the Hwy.
My personal best drives were about 70mpg just cruising about 40 miles and 80 mpg on a 21 mile commute to work.
All of my numbers posted here are measured at the pump. The trip computer underestimates by about 2-3 mpg, on average. I've kept a spreadsheet with all of my mpg numbers I can post here sometime if anyone is interested.

May I suggest a site like FuelEconomy.gov - The official U.S. government source for fuel economy information. and/or Fuelly - Track and Compare your MPG ? It helps to promote the HAH, and you can put the results in your signature here.

I'll check it out. Do you know if data can be entered retroactively?

Yes, it can, on both sites. You have to include a date with each entry.

filled mine up at the pump yesterday... 212.1 miles on the trip meter, pump read 4.64 gallons... 45.7 mpg... the more I drive it the better it gets, this is with ~2050 miles on it now... about 50/50 mix of city and highway for what little I do these days... staying at home sucks

and, I'm basically seeing what others have noticed... the instant economy gauge reads about 2-3 mpg lower from what you calculate at the pump... dunno why that would be, just a quirk to get used to I guess

 

[RickBlaine]

I have a 7th Gen 2.4 (4 cylinder) engine with a 5 speed automatic. So why am I posting in your thread? Because last week was the first time I put gas in it in about 9 weeks. So I feel like an honorary 10th Gen Hybrid owner using his car every day. Now I know what the fuss is all about- I almost forgot how to add gas.

By the way- I get 34 on highway and 24 in the city. Pathetic, I know....

Wife is pushing for a Hybrid.

happy wife, happy life...

in all seriousness... yeah, go for it, the iMMD setup is really nice

I collected some interesting data points recently about how significant hwy speed matters.

Traveling routinely to NYC from New Haven then back, about 75 mile one-way, either I-95 (much less hills) or CT-15 (much more hills).

First we see ‘to’ data because the three times I almost followed identical navigation instructions. I pick a speed and try to keep this as much as I can on hwy. When I arrives, I read the avg. speed and mpg from the instrument panel. Doing the math, it seems staying at 60 mph will save me almost 0.5 gal more fuel one-way than 75 mph, at a cost of 11 min longer.

The ‘back’ data is not comparably significant, because I took CT-15 for the first 2 times and I-95 for the 3rd time. By principle CT-15 would cost more due to frequent uphill/downhill. Still, I’ll try 65 mph on I-95 next time if there’s no construction.

Hmmm, I'm not sure that I believe these numbers are accurate. You may need to have your trip computer re-calibrated. I think maybe by changing different tires back and forth your computer is a little confused. Seriously, unless you are driving downhill, with the wind at your back, there is no way you are getting that kind of MPG.

 

[rgoodman]

Did you know that you can have the dealer calibrate your Accord for your exact tire size? They can go into the your car's system and set it for any tire size.

his winter tires are smaller diameter than the stock ones I would guess... that's the only way it's going to read a consistent 25% better fuel economy than what the vehicle is rated at... any other answer / excuse is a fish story

 

[OG1]

The numbers are absolutely accurate. I've kept track since the third fill up, the last 14k miles (30 fill ups). All tank mpgs are calculated at the pump after fill up. My winter tires are stock size, and the highest mpg I reported are on all seasons that came with the car.

Can you please explain how one would only drive down hill for 14 k miles? I usually end up at the same location at the end of the day where I started started...my home.

Attached is my trip computer from the other day driving to work. It was reset prior to my departure, at which time I started with 4 bars of battery charge (same as ending). You can see even the trip computer estimates 700 mile range. My return trip the same day showed about 66mpg... The average is still over 70 mpg.

 

[johnbell2]

that's great, but no one I've seen posting their mileage can reproduce those numbers... that pic shows you're in EV mode which skews the numbers on instantaneous... there's no way you're getting 60 mpg in normal driving under normal HV mode

 

[OG1]

The numbers are not instantaneous...they are average for the trip. The EV mode only skews things if you start with full battery and end the trip with empty (I've already addressed this) and with HAH battery size the difference would be marginal over a 20 mile trip. The EV mode makes no difference whatsoever....and just to be clear the only time I turn on EV is when I'm parking to avoid ICE turning on while in my garage or before I can take a picture (in this case).

Not sure why you are so vested in using completely false reasoning in disproving my numbers.

 

[OG1]

For your convenience, I went down to my garage and took pictures of my trip A, which is reset at beginning of every drive, and trip B, which is reset at fill up.

Keep in mind at the pump I constantly get 3 mpg over the trip computer when I'm close to 60mpg mark.

 

[Ziyang]

The numbers are absolutely accurate.

I don't think you have any purpose of intentionally fake numbers...

60+ or even 70+ mpgs are of course fantastic and what I also wish to have. It's just nobody else can ever reach this level, and therefore we are wondering if your vehicle has made some systematic errors. But if not, it will be great that everybody can learn from your success and gain a 20% better fuel economy.

A few of my thoughts regarding your numbers.

1. Do you fuel your car with ethanol-free gas? Ethanol comes with 33% less energy than gas, so compared to common E10 gas (contains 10% ethanol), ethanol-free gas should give 3% better numbers. Costco once had bad reputation for putting 25% ethanol (I don't know exact number) in their gas, thus causing significantly shortened mileage; now they are doing ok with 10% ethanol (they claim so).

2. Have you looked at other distance source than the trip computer? For example, you may start Apple Map navigation, which will show exactly how many miles the trip is, for your next long trip at the beginning and reset your trip A. Then, you can compare with your trip computer to make sure it doesn't over-estimate your mileage when you arrive.

When people are referring to tire sizes, etc. those factors would finally affect point 2 mentioned above. After all, your fuel economy is calculated from mileage divided by gas volume. I think you can start looking into these two factors.
