Assessing your driving habits is crucial before you decide on the different fuel types available. On a regular week, how far do you drive? Do you engage in many brief trips, or are your drives generally longer in distance?

Electric cars, plug-in hybrids and petrol are great for short distances. For long daily driving, electric cars are a strong choice if you can charge. 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 may still be relevant in some cases with very long journeys and lack of charging options. Consider that in many countries, cities have banned the entry of diesel engines with high emissions.
