Although My Honda+ has its faults, I think it is proving to be a little more “reliable” of late, so I thought I would share some data from recent Journeys, together with stats for AVG miles/kWh. I have been pleasantly surprised with the results lately, so will combine with Average Speeds and Max Speeds from App, to show the range. Unfortunately the App still doesn't yet show my quicker return trip today, only Outgoing. Ambient temp around 6°C with E wind chill. So not warm.

So first this is my table of recent trips, which shows 3 short local trips to buy a morning paper. Quicker trip home today so only 3.0, compared with the average 3.6 or 4.1 on Sunday, which was very sedate, but cold!

I also find that on days where I have been out early, rather than use my e-bike, because ambient temp is around 2°C plus wind chill, I get much better economy on the 2nd journey that day.

You can see these longer trips are achieving 3.9 or better. The exception is my trip to Bath (for an eye test) which was a much quicker run both ways. And I got a Driving Score of 999 coming home, which is a joke. Outgoing I reached a Max of 82 overtaking (didn't want to follow a diesel van). So not always driving like a Saint.

On my outward trip to Bruton today, I arrived with 6.6m/kWh but this is downhill. Going on to Shepton Mallet Tesco to charge we were at 4.6, and then coming home, the economy dropped overall to 4.1 - but that was in part a spell chasing a large Merc 4x4 for awhile, who was clearly “in a hurry” to get somewhere!

One other factor that may be helping my overall economy, is my habit of free top up charging at Tesco. That would apply to Shaftesbury & Shepton journeys, but not Frome or Bath. That must be keeping the battery juices nicely fired up.

And I couldn't resist adding the App shot that shows Temp inside my car as 22°C this is never right, although it did show 15°C until I refreshed it !

Hope this is of interest to some. I'm not using much heating, sometimes the wheel & seat, on early trips, so drain from ancillaries is minimal.

Another thought added today. Going down to Post Office today, I achieved 6.0m/kWh max en route and arrived with 5.0. Round trip AVG 3.7 which was good, given ambient temp was 0-1°C see below. So I wonder whether my “downhill” leg in One Pedal mode, with Max 3 chevrons helps to “warm up” my battery, and hence gives me excellent economy over such a short run, in cold conditions. No heating, just wheel warmed for a bit. I was dressed for the cold, and only a short trip.

Thanks for posting these. If it's got 28.5 kWh of usable battery, I would assume that anything above 3.5 m/kWh means more than 100 miles of range. With 4.1 getting 116 miles.

I thought you had to go to Barnard Castle for that?

Good one, especially all the way from Denmark! Fortunately Cummings is history.

Ok, so this set of Journeys today were gentle. It's Mothers Day, so a relaxing trip out with the wife, some shopping, exercise and coffee. But unbelievable stats, considering this includes some stops & starts. No heating or aircon. No radio.
Charged overnight to 80% was showing 79% by the time I was out of garage, and 60% on return. So travelled nearly 26 miles, using only 20% battery. 9°C

I have rarely achieved this in the height of Summer.

That's almost the WLTP range.

That's pretty neat. How diligent are you in keeping the tire pressure at it's optimal?

Here's me since my last charge. Pretty much bang on WLTP, right?

When my car was at the dealer having it's door handle replaced last week, they gave me a Honda e with 17" wheels as a courtesy car (mine has the 16" wheels). I did notice that the ride was slighty firmer/harsher, but I was more surprised that the economy was noticably worse. On the way home (overall downhill) I got 4.5 miles/kWh from the 17" wheel car, but in my 16" wheel car I got 5.8 mile/kWh (slightly different route, more traffic). On the way there the difference was smaller - I think it was 3.5 and 3.7 miles/kWh. So overall for each car it was an average of 4 miles/kWh (17" wheels) and 4.75 miles/kWh (16" wheels) over a total distance of about 10.5 miles. So for a full charge that's a range of about 125 miles and 148 miles - a bigger difference than I was expecting.

The courtesy car had not had it's trip meters reset since new, and it was giving an average consumption of 2.5 miles/kWh, whereas my average is around 4.2 miles/kWh over the last ~650 miles! (I suspect a large part of that is probably because I don't use the heater and air-conditioning as much as most people.)

Expected range would be 114&135 as only 28.5kW available, unless you choose to explore how much you can extract blindly under the 0% soc (manual advised to charge immediately at 0%).

@ Honda's qouted efficiency of 3.5m/kWh on 17" wheels would be just under 100 miles. My experience matchs Honda's qouted efficiency unless actively trying to achieve economy.
Good on the eye, great to drive, efficiency.........
