I think that we’ll have to agree to disagree.

What efficiency do you get yourself?

Driving very carefully, I can get near 12 kWh/100km (on a round trip, same altitude at start and end point!!), which is around 5 miles/kWh. Usually, it's more like 15 kWh/100km, so around 4 miles...farest range on a full charge was 210km (100-0%) so far

Same here. Didn't reset my trip meter since purchased the car. With 2k km on it getting an average of 14,9kwh/100km, which is about 4 miles/kwh. I can believe in reaching 5 miles/kwh on a good day (16" tires, city driving at low speeds etc), but 7 miles... There is either a difference in how you are reading your consumption or how the consumption is displayed for different markets.

Today, I had a consumption of only 0.5 kWh/100km on a 2 km trip. That's 124 miles/kWh...Guess what's the reason ;-) you can only compare achieved consumptions when your start and end point is at the same altitude...

Therefore you are stating that the real world consumption of a BEV journey over the following two elevation profiles (where the start & end altitude are the same) would be identical (assuming all other external factors were also identical):

Altitude is only one factor, in reality it is impossible to compare consumption, simply because there are too may other factors involved, temperature, humidity, tyre wear, just to name a few but the driver probably makes the biggest impact with their inconsistency.

I think that the speed is the main factor here rather than the altitude. There is no point to measure consumption on a one way trip, since if you are going down you will have to go up on your way back. On the other hand, driving in city speeds greatly improves consumption (at least by my experience). So yes, if you are using the Honda only for city driving, it is probably possible to reach 7 or even 8 miles/kWh figure. But if you are doing some mixed driving, 4 miles/kWh is a more realistic figure :)

I almost completely agree. Altitude is only one factor, but here it's the biggest one. if you really want to compare consumptions, it is essential to try to eliminate possible sources of error. Doing a round trip and having start and end point at the same altitude is rather easy...other factors are less easy to control... I seriously doubt, that one can reach 7-8 miles per kWh on a round trip but I'm curious to see the counterproof 😊
