Does this make sense?
My E is around 4.5 miles/kwh and my October electricity wll be 34p per kwh (up from 28p now) so that will be around 7.6p per mile.
My Jazz EX is around 56 mpg so far (only few weeks), at £1.60 a litre = £7.28 a gallon, so that is around 13p/mile. (1 litre = 0.22 gallon)
My old Civic was around 34 mpg so almost double that.
Your numbers add up.
I had an e for a year and made a sudden decision to sell it and ordered a new Jazz. That was partly driven by the expected rise in electricity prices of 50p+, 70p+ and £1 later in 2023, prior to the current Government intervention, the dealer offering more than I paid for it as well as some practicality issues that are better addressed for me by the Jazz.
My 1 year average in the e was 3.1miles/kwh and for the coming winter, I would unlikely better 2.5-2.8m/kwh. No road tax on the e, but road tax on the Jazz, the e needed a £600+ charge point which adds around £3.70 per charge assuming 2 charges a week, depreciated over 3 years.
As things stand today, overall the running costs are similar, but I gain the better practicality of the Jazz, but lose the driving dynamics of the e.
If I had to rely on public chargers, some are now charging up to £1/kwh, that would have made the e so much more expensive to run and not viable.
Now the several month wait for the Jazz to arrive.
