This is not a straightforward comparison as there are many variables, including your mileage, the kind of journeys you will make, your electricity cost at home and at public chargers and so on.

Assuming you cover 1000 miles a month at 66mpg, a hybrid would cost approximately £110 per month in fuel costs. Comparing this with a Citroen C5 X and your home electricity cost of 30p per kW/h, the EV would cost you approximately £80 per month in electricity.
