Supermini Economy Heroes

You can’t turn on a news report at the moment without hearing about the state of the world’s economy – but it’s your car’s economy that will have a bigger impact on your monthly motoring bills!

These days, the miles per gallon figure can make or break a new car, and manufacturers know it. That’s why Ford has launched its Fiesta ECOnetic, saying that it emits the least CO2 and delivers the best fuel economy of any mainstream car. It’s time to put those boasts to the test!

To find the best frugal model, we’ve brought together five small hatchbacks with lofty mpg claims, each of which has something different to offer. In order to take victory in this test, a car will need penny-pinching running costs and everyday usability rolled into one.

The Ford’s first challenge is to see off the well established Polo BlueMotion. Not many models in showrooms at the moment emit less than 100g/km of CO2, but until now, the Volkswagen has been the best of the bunch. We’ve also lined up a smart-suited new premium model, in the shape of the ultra-frugal oil-burning Alfa Romeo MiTo.

But what about petrol options? Unleaded is now around 10 per cent cheaper than a litre from the black pump, so don’t bet against the featherweight three-cylinder Subaru Justy or Honda’s entry-level 1.2-litre Jazz.

Each car was brimmed at Fleet Services on the M3 in Hampshire, before we headed along the A303 to our photo location on Exmoor, Somerset. After a 300-mile round trip, we filled up again and calculated how frugal these fuel sippers really are!
