3THIS IS JUST AN ESTIMATE: We've taken a vehicle that it more or less comparable. We're not making promises here. It's simply to make the point that you can save money by not spending as much on fuel. Fuel meaning what powers the car. That could be Petrol, Diesel or Electricity. We're not lying or trying to decieve you – so don't hold us to it. It's an estimate.
**How we've calcualated this estimate:** The running costs are estimated based on the selected mileage and the type of fuel that is used to drive the vehicles. In case of electric vehicles, the cost per mile is calculated based on the vehicle’s battery capacity and the WLTP range of the vehicle. The total cost is then a multiple of cost per mile and the annual mileage.
**Electricity cost** = (Battery capacity kWh x UK Average electricity cost 4 £ / WLTP range miles) x Annual Mileage miles
For the combustion vehicle, a comparable model in price and performance is chosen. The amount of fuel required to cover the mileage multiplied by the cost per gallon would provide the total cost.
**Fuel costs = **(Annual Mileage miles / MPG miles/gallon) * Fuel cost per gallon5 £/gallon
The savings is the difference between the two.
