Thinking aloud 😂
I will use your calculation save scrolling back to mine.
Lets say 6 charges netted you 210 miles (@35 miles per charge) at a cost of £17.83.
Now cast that aside for now.
Meaning your remaining 269 miles was done on petrol(ish) at a cost of £40.75, roughly 41.5mpg.
Bringing back into the equasion the cost to charge and converting that to gallons (17.83 / 6.27) = 2.85 gallons – 210 miles / 2,85 gallons = 73.7mpg
HEV – 41.5 mpg
EV – 73.7mpge
Or 57.6mpg overall
Which at 1am is a more accurate calculation and from here you can easily work out miles per kWh 😂
