The Honda E in my hands for a year, whilst a terrific city car, was very disappointing in efficiency, averaging just 3 mile/kWh over the 12 months, whereas my Jazz has average nearly 57mpg over the same 1 year period with similar use.
That's pretty poor, my E is around 4, and most on the forum talk about 3.5 to 4.5 which is about average. All depends on many variables I suppose, my second car milage is not even worth having night time electric charges compared to the best deals overall. My Jazz is currently 63.3. The Ny1 I wouldn't even look at.
Yes, very poor. Summer it was low 3's, winter high 2's. I think the issue was the high number of very short journeys, where the E tended to use significant battery on start-up, probably initially to heat or cool the cabin and I also think to bring the battery pack up to normal operating temperature.
On a particular longer run(15 miles) the E would average around 3.5, but usually below 4, whilst on the same run the Jazz averages 74-75mpg, every time without fail.(My Jaguar 24/25mpg for comparison)
On one bitterly cold icy/snowy 20 mile run, the E failed to better 2.
In general EV's from other manufacturers, seem to easily exceed the Honda EV's efficiencies
