Diesel cars have reduced in popularity since the introduction of clean air zones such as ULEZ, the ultra-low emission zone in London where most diesel vehicles incur charges. However, diesel can still be the fuel of choice for some drivers, so before you decide on your next car, read our guide to the future of diesel cars.

Should I choose a diesel car?
Drivers who cover less than 12,000 miles in a year or drive small to medium sized vehicles are usually better off with petrol cars. If you are concerned about air pollution or mainly drive in cities, again, petrol is the fuel of choice.
A diesel vehicle should be considered for drivers who cover large mileages annually and who drive large vehicles such as SUVs or pick up trucks. The savings from diesel fuel economy may outweigh the additional purchase cost. Diesel engines are generally more efficient than petrol engines and require fewer revs to get them moving. This also contributes to fuel economy.
Additionally, drivers who regularly cover long distances often drive outside built-up areas in places where air pollution is not such a great problem. Paying to use clean air zones could potentially cancel out fuel savings, so this depends on the areas in which you regularly drive.
Large company cars are often diesel and although the new system of car tax has reduced the benefits of most diesel vehicles, company cars are not included in this. If you are looking for motor trade insurance you can find an online motor trade insurance quote online and you can also check out the position for large company cars. Because new vehicles comply with the new Euro 6 emissions regulations, they are not affected by clean air zones.
When is petrol the best choice?
For small and medium-sized vehicles, petrol engines can often be close to the fuel economy you would get from a diesel and the cost of buying them is normally lower. For driving in cities and built-up areas, petrol is usually the best choice as you avoid the charges that diesel drivers experience. Petrol engines are also better for the environment as they emit fewer pollutants than diesel vehicles.
