Perhaps not surprisingly, it is much cheaper to run an electric vehicle than one that uses petrol or diesel. EVs do not require the same level of maintenance as regular cars, which need filter and oil changes, and the brakes on EVs wear much more slowly than on traditional vehicles, so you will find yourself spending less money.
One thing to watch out for, however, is the insurance costs, which can sometimes be slightly higher than in the typical petrol-fuelled car.
