Small SUV is relatively cheap to run
Think carefully whether you need diesel

When it comes to fuel economy, the cheapest on paper is the 1.6-litre diesel with its claimed 57.6mpg. The petrol 1.4 returns 45.6mpg and the 1.0-litre T-GDI between 46.3-47.1mpg depending on the gearbox.

2017 Kia Stonic 1.0-litre T-GDI badge 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.

The diesel produces 130g/km of CO2 in regards to emissions, while the turbocharged 1.0-litre petrol emits 138-139g/km. The 1.4-litre MPI emits the highest amount of CO2 with 141g/km.

Is it reliable?

While it’s a new car, the Kia Stonic should prove a safe bet when it comes to reliability. The carmaker has forged an exemplary reputation for solidly built vehicles over recent years, and since this new model is based on the proven Rio platform with no new engines or gearboxes, all the indications are there that you can rely on your Stonic. The Stonic also comes with a seven-year, 100,000 mile warranty.
