Price comparison of popular fuel types for MG MG3:

We advocate for a careful review of your driving habits before you commit to a fuel type. In an average week, how much distance do you drive? Are you more inclined to take short drives or to go on longer journeys?

For short trips, range is rarely a limitation, so electric, plug-in hybrid or petrol can be fine. For longer daily journeys, consider an electric car, especially if you have the option to charge at home or at work. 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 several countries, diesel engines that emit high levels of pollutants are barred from urban areas.
