1. Suzuki Celerio 1.0
Official combined mpg 65.7 True mpg 57.8 % difference 12%
Despite being one of the cheapest city cars around right now, the Suzuki Celerio comes with a decent array of equipment and all versions come with five doors, air conditioning, a DAB radio and Bluetooth connectivity. We also like the Celerio's 1.0-litre petrol engine, which is handy as it's the only option available. Compared with some of its direct rivals, the Celerio fared well in our True MPG tests too, being only 12% adrift of its official fuel economy claim.

Mini Cooper 1.5 3dr
Official combined mpg: 60.1 True mpg 41.3 % difference 31.3%
Stylish though it may be, this three-door version of the popular Mini hatchback is far adrift from its official fuel economy claims. Although, in reality, it's still not far off our top 10 entrants.
