So (based on the info in the original post) of 33mpg
33mpg means 4.5litres for 33 miles - yup
190 miles (min range of SR) 44kWh - this should be 51kwh I used the original capacity zs I apologise
So 5.75 gallons is 27 litres - yup
x £1.90 (what the op said) is £51
Even at an excessive 60p per kWh (it’s now being capped at 34p)
That’s only 60 x 51 is £30.70 and therefore still £21 cheaper over the course of 190 miles
Again that’s using the shortest quoted range for an SR and triple the current cost of electricity (double of what it will be in a weeks time) and the figures the op quoted regarding efficiency and fuel costs to him
My maths was all good but thanks for asking
