If you primarily drive short distances, electric, plug-in hybrid or petrol is typically a good fit. For longer commutes, a newer electric car is a good alternative - especially with access to charging. If you have a daily commute over longer distances, a modern electric car can be a great choice - especially if you have access to charging at home or at work. Diesel cars can still make sense if you drive very far and don't have access to charging. Remember that in some places, high-emission diesel engines are not allowed in urban areas.
