Costs & verdict
Everyday costs, plus how reliable and safe it is
Costs, insurance groups, MPG and CO2
The entry-level version of the Kia Stonic is only slightly more expensive as a cash buy than the Citroën C3 Aircross but manages to undercut the Ford Puma, Renault Captur and Seat Arona.
While we’ve yet to put the mild-hybrid petrol through our True MPG test, our test car regularly managed to achieve more than 40mpg (if the trip computer is to be believed). That said, it’s worth remembering that the Puma will be even more efficient while offering more power.
At the top of the Range is GT-Line S. Over GT-Line it gets two-tone paint, heated seats and a heated steering wheel, but it’s very pricey.

Reliability
Kia as a brand came a respectable ninth out of 30 manufacturers in the 2021 What Car? Reliability Survey. The Stonic itself has yet to feature in the results.
If something does go wrong, there's always Kia's seven-year warranty to fall back on – the joint-best in the class. UK and European roadside assistance is free for a year and available at a reasonable extra annual cost thereafter.
