I've averaged £3.80 per 100km which is about 6.1pence per mile.
edit: the car calculates the cost per 100km based on my home electric unit rate. In reality, it costs me a lot less than that because I use free chargers for at least a third of the charge I put into it.
I found what looked like a reasonable online calculator which said eV was near what you said. 6.4p/mile
I put my figures in.
As I thought. Not for me unfortunately.
But not as far off as I thought
Petrol = 180p/l
Electricity = 22p/kWh (my rate)
Current car = 1.6 auto
eV = ioniq 5
Miles per month = 300 (probably too much)
Said I could save 666 pounds a year.
So this isn't enough with depreciation for me.
But put in my old commute and bang. 2k a year saving.
