Kia Stonic: what will it cost me to run?

When it comes to fuel economy, the cheapest on paper is the 1.6-litre diesel with its claimed 67.3mpg. The petrol 1.4 returns 51.4mpg and the 1.0-litre 56.5mpg.

Insurance groups will range between 10 and 14 depending on specification.

Residual values haven’t been worked out yet at time of publication, so it’s difficult to comment on PCP rates, but it’s looking like the Kia Stonic’s running costs should be low enough to be competitive.
