The What Car? True MPG technicians test new cars every week. While the official Government figures come from a laboratory test, our team takes each car on a thorough road test that produces the data needed to deliver real-world MPG figures.

Here's our round-up of the most fuel-efficient small cars on the market today. All achieve more than 50.0mpg, with many returning more than 60.0mpg. The majority of the cars are diesel powered, but a petrol hybrid and a few petrol city cars also manage to make the cut.

1. Citroen C3 1.4 e-HDi 70 Airdream – official 83.0mpg; True MPG 70.3mpg

This diesel Citroen C3 is the only car in the list to return more than 70.0mpg. It might not be our favourite small car but a True MPG of 70.3mpg could prove very tempting to some buyers.

2. Volkswagen Up 1.0 75 – official 61.4mpg; True MPG 63.5mpg

This is the more powerful of the two engine options available in the Up and it’s managed to beat its official fuel economy figure by 2.1mpg. It’s the most efficient city car our True MPG team has tested and also one of our favourites.

3. DS 3 1.6 e-HDi 115 Airdream – official 74.4mpg; True MPG 63.0mpg

4. Suzuki Celerio 1.0 Dualjet – official 78.4mpg; True MPG 62.9mpg

Suzuki’s Celerio is a great city car. It offer decent value for money and, thanks to a True MPG figure of 62.9mpg, running costs will be low, too.

5. Mini Cooper D 3dr – official 80.7mpg; True MPG 62.6mpg

The new Mini hatchback's official fuel economy figures are an improvement on the previous car's, and it is more efficient in the real world as well. The new Cooper D 3dr recorded a True MPG figure of 62.6mpg, although this is some way below the official figure of 80.7mpg.
