It's such a shame, if it had decent efficiency that battery would go far and it would be pretty much perfect.

You can always change to lower roll resistant tyres but that would come with a hefty price.
These would be the best tyres for it, front and back.

I wonder how much difference they would make to range and noise.

The Michelin Pilot Sport 4 tyres at the size on the Honda e are rated either C or E depending on which exact version is fitted.
Those Primacy tyres are A rated and the difference in economy is around 9% between A & G rated tyres, therefore if we assume 6% between A & E and 100 mile range, then that's about a 6 mile difference.
This does not account for the differences banded about by the reviewers.

I suspect that is a controller software issue, in which case if Honda maintain and improve the software then there's a possibility of increased efficiency in the future.

3 years ago I changed all 4 tyres on my Yaris Hybrid and went from E to C and made a 10% difference in mpg. I went from 70mpg to almost 80mpg instantly. I could clearly notice the difference while driving. It made less effort to go forward. Also I went 4db less on the label and even that made a noticeably huge impact in noise on bad asphalts. So from that time I started to believe that tyres choice make a huge difference and I cannot imagine what would be the mpg if I had A rated tyres. After 3 years I am still doing around 77mpg on 15miles round trip. On longer trips I will do more than 80mpg, typical hybrids.

*The best for the 17” rims. Low resistance tyre on the 16” should be even more efficient, since the wheels are narrower. Would be interesting to see a side-by-side of the most efficient 17” vs the most efficient 16”, to see how much can be achieved just through tyre choice and how much is fundamentally down to the smaller overall contact surface and air resistance.

Not surprising since -3dB corresponds to halving the sound power.

New (Dutch, sorry) test in practice for range at 100 and 130 km/h (= +/- 60 and 80 mph). https://www.autowereld.com/nieuws/auton ... en-100-kmh

Thank you. Confirms Bjorn's findings, 160km / 100 miles range at 100 kph / 62 mph.

So really you need to charge every 130km / 80 miles or so, and charging is rather slow.
