16. Volkswagen Polo 1.4 TDI – official 83.1mpg; True MPG 56.2mpg

The VW Polo has impressed our road testers, to the extent that it earned a five-star rating. It's not the most efficient small car, with its True MPG rating some way short of its 83.1mpg official figure, but 56.2mpg means you'll still travel a fair way between fills.

17. Toyota Aygo 1.0 VVT-i – official 65.7mpg; True MPG 54.0mpg

Another Toyota has made it into our round-up and this one is petrol-powered as well. The new Aygo is a striking city car that promises to be cheap to run thanks to its True MPG figure of 54.0mpg.

18. Suzuki Swift 1.2 - official 56.5mpg; True MPG 51.7mpg

The Suzuki Swift’s appeal lies in its low prices, high specification and fun character. This 1.2-litre petrol can’t match the headline economy figures of the newer Dualjet unit but it still proved efficient in our real-world fuel tests.

19. Mazda 2 1.5 - official 62.7mpg; True MPG 50.8mpg

The Mazda 2 is a good small car that’s well equipped and reliable. This is the mid-range 1.5-litre petrol engine that produces 90bhp and returned an impressive 50.8mpg at the hands of our fuel testers.

20. Renault Twingo 0.9 TCe - official 65.7mpg; True MPG 50.0mpg

There aren’t many small cars that stand out as much as the Renault Twingo. It’s got retro looks, the engine’s in the rear and the turning circle is very tight, making tricky city manoeuvres easy to pull off. The 0.9-litre petrol engine can’t match its 65.7mpg official figure but still returned an impressive 50.0mpg in our tests.
