MPGs with 2023 Hybrids

As I've gotten used to driving a hybrid, I've found it quite interesting how driving habits seem to impact fuel economy in ways I didn't initially expect. I likely will not change my driving style in the interest of maximizing fuel economy over time, but in the past week or two have paid a bit more attention to check if my 23 touring model is in the expected MPG range. So far it definitely is with my average in the 42-44 range with mixed city and highway miles. But with some caveats ...

If you truly push the car non-stop very aggressively, yes fuel economy suffers and you'll be lucky to be in the 30s especially if you're in a hilly area. No surprise there. But ... on the flip side if you drive the car very conservatively as if you were trying to conserve gas (as I would in any other traditional ICE), fuel economy also seems to suffer. That is, If I gently accelerate to desired speed with light pressure on the accelerator, the engine is on the entire time fueling either the battery or the drive motor, and the direct drive clutch is not engaged until you get to desired speed. Fuel economy suffers this entire time. However, if I accelerate more briskly to desired speed - whether it's 40, 50, 60, 70, whatever - then settle into that speed, the engine turns off and you're EV, or the direct drive clutch engages for higher MPGs. Maybe this is old news for hybrid owners, but I found it quite interesting. And I've found it very useful to use regenerative breaking to both charge the battery and save the brakes. In a few short weeks, driving a different car that doesn't have this feature is suddenly odd! I really like that feature. Regardless, it's been refreshing that in my limited experience more aggressive driving actually seems to yield better MPGs!

Curious if others have noticed this?

As I mentioned in the first post the gentler I drive the lower the MPGs. (to a point ..
can't drive Ultra aggressive and expect to be in 40s range). Accelerating more rapidly to desired speed increased MPGs in my experience. I'm in 42-43 range consistently mixed highway city. Highway alone seems to dip to 39-40 for me. This is touring with 20" wheels btw. Give it a try and experiment. It's easy to see avg mpg on screen each drive or you can reset trip computer. And yes use regen paddles if you care about efficiency - brakes do some regen but i believe less than paddles.Hope you see improvements!
Touring comes with 19" wheels and tires. Did you put some aftermarket larger ones on?

I have read some "expert" say similar things about maximizing mileage on the Honda hybrid system. As for myself, I have the Touring with just over 800 miles on it so far. I have to admit, I drive it very gingerly, in Individual mode which I have selected all of the economy attributes except for the heavier steering. The trip computer says 41.9 mpg to date. I noticed it getting better and better as time goes on. Not sure if that is from rising temps or break in. It seems that for short trips in colder weather, the mileage is not very good because the ICE motor is running a greater percentage of the time to get the engine up to operating temperature and the cabin warmed up. I have gone on some shorter trips, mostly county roads (45-60 mph) and gotten over 47! Also noticed, highway driving into a strong 25-35 mph headwind only got 37mpg over about one hour or 50 miles of driving. Made up for that though on the return trip.

Oops getting cars mixed up - my mistake! Yes, accord has the 19 inch tires.

Same here - on my fifth tank and better average mileage each one. And also weather warmer here on average each tankful (really don't need heat nor ac right now). Only other difference is that I accelerate a bit more aggressively now versus earlier tanks. But it really might be weather driving the improvement.

Just did my first actual fill up. According to fuelly, 40.7mpg. Better than the cars read out. I am impressed that it got that high considering it’s been sub 50deg most of the time.

For those curious, just did a 10 mile journey to and from doggy daycare on city/suburban drivings. Drive there I had the heat on and was driving carful since the pup was in the car, 30.5mpg. On the way back no heat on, car was already warm and driving more aggressively, 54.8mpg. Goes to show much ambient temps (mainly to heat up the engine and battery) and climate control impact fuel economy
3000 miles so far. All fillips right around 50mpg
17" wheels or 19"?

Mine is the ex-l with 17” wheels . Prefer look of the sport wheels but liked the idea of an extra 4mpg
I am at 3k miles and my average MPG is 35, it's way lower than the estimate. From an efficiency perspective this car is an disappointment. I should have done my homework better.

What is your Avg. Daily commute speed? Mine is 75-80 mph and this car is not in it's efficiency zone.

What trim - touring?
I now have around 1200 miles on my 2023 touring hybrid with 19" wheels. I finally crossed 38 mpg threshold this week and that is from mile 0 as I haven't reset to track each tank. i drive 45 min each way daily and 80% highway in central PA. it seems to be going up a 10th or 2 each week. maybe weather, maybe break in? I ran in eco mode for about a month and then decided to say "screw it" and run in normal mode on highway and pop into sport mode once and a while on short trips around town. If I could get to 40 mpg no matter where I drive it i will be very happy. I never had 17"s to compare but i think the ride is smooth. would i like 4 more mpg with 17's? sure. But my aftermarket 19's with gloss black painted caliper looks really sharp with the Pearl White. The real issue will be winter driving on these with all season or put oem 19's back on with snow tires or buy 17's and run snow tires? I heard the cross climate 2's do very well as all season tires even in snow but they are pricey and also will prob lower mpg by 3--4 mpg...

I didnt really research hybrid pros/cons before buying and just thought 44/41 on sticker was pretty much guaranteed. Next time around will know better and do more research. But to me the car drives and looks great!!

Yeah - 75-80 is not that efficient. Should be a little better though. I get low 30's in my '13 EX at that speed. But if I slow down to 65 it's around 40 or a bit more. 55 mph and I'm close to 50 mpg. Speed has a huge impact as do wind, temperature and a/c use. Going 80 into a headwind in temps around 0-10 F and I'm at about 27 mpg. My best tank has been 54 mpg. 740 miles averaging about 65 on a couple of warm days (but not warm enough for a/c) and a slight tailwind. Also went from 5,000 ft to about 2,000 in elevation.

So a lot of factors involved and huge differences can be expected.

On trips where I am doing around 75mph or so and care more about getting there than mpg, my 2017 Accord Touring hybrid gets about 38-39mpg..... So doesn't seem that far off for those speeds with 19" wheels vs the 17" on mine.
2023 hybrid sport. After almost 300 miles I am at a bit over 47mpg with an even mix of street and highway driving. I'm not very aggressive with the gas but drive at speed limit to 5+ mph over. Mostly flat roads, not many hills. Mostly drive in economy mode, but some sport mode as well.

That's pretty accurate. If not aggressively driving, the hybrid trims equipped with 19" wheels can achieve high 40s MPGs in mixed driving. With the 17" wheels, these hybrids can get above 50 MPGs.

I test drove a 2023 Accord ex-L yesterday and was very confused about the regen paddles. You use the paddles to produce regen when slowing, but for the next slowdown, you start from zero with the regen? Does a driver need to use the regen paddles religiously to get the max city MPG? When the FEDs do the mileage testing, are they using the regen paddles? What difference in MPG can a driver using the paddles aggressively produce versus ignoring them?

I like to be involved in my driving (sure do miss the manual trans) but flipping the paddle seemed tiresome...
