Most Economical Superminis

Here are the top 10 most economical superminis in the U.K. ordered by their combined MPG figure.

Any of these cars will save you heaps of money on petrol, as long as you are happy to compromise on the lack of space. Having said that they do have more room than you think they would. I've actually taken a Smart fortwo on a camping trip with another person in the car.

Not only do they offer great fuel mileage but they're also very practical for city driving where its good to be small. Smart cars can get into a lot of parking places that others can't!

Smart fortwo

The most economical supermini is the Smart fortwo diesel.

Not only is this car incredibly small and light but it has a tiny 3 cylinder 800cc diesel engine which helps it achieve top spot in both the supermini rankings and across all vehicle classes in the U.K.

The engine does however only produce 45 bhp and as a result its not a quick car, taking almost 20 seconds to reach 60mph. It still feels nippy around town though.

Smart's owner, Mercedes, says the car has the lowest carbon footprint of any current vehicle worldwide producing only 88 gCO2/km, around half the carbon emissions of an average UK car.
