Before deciding on a fuel type to buy, we highly recommend taking some time to consider your current driving habits. Do you only use your car to get to and from work? Is the distance less than roughly 35 miles each way?

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. For longer daily commutes, a modern electric car is often suitable - especially if you can charge at home or at work. If you often drive long distances and can't charge, diesel can still be a viable option. Be aware that in a number of countries, cities have implemented bans on diesel engines with high emissions.
