City cars are all about diminutive size and manoeuvrability because they invariably spend most of their time on our increasingly crowded urban streets.

They do need to be big enough for a couple of adults, with back seats that’ll suffice for occasional use by people – or as a dumping ground for a couple of large shopping bags – but they must also be small enough to nip in and out of traffic, and squeeze into tight parking spaces.

Out-and-out acceleration isn’t crucial, but there must be enough oomph in the lower gears to scoot into gaps that appear in the traffic. Running costs should be low, too.

Fortunately there’s never been a better line-up of city cars on offer. Kia's Picanto mixes a neat, functional interior with tidy handling and a surprisingly big boot, while the Skoda Citigo and Suzuki Celerio are cheaper and even more frugal.
