Kia Stonic SUV - MPG, running costs & CO2
Kia Stonic running costs are reasonable but not class-leading
Stonic buyers are now limited to just two versions of the same 1.0-litre petrol engine, so there's very little choice. Both manage reasonable economy - the engines roughly match the equivalent engines in the Skoda Kamiq - but a diesel Peugeot 2008 is noticeably more economical than any Stonic.
While both versions of the petrol engine offer decent efficiency, Kia is missing a trick by not offering a hybrid or even plug-in hybrid version, like it does with the Kia Niro. Alternative fuel rivals include the Renault Captur E-Tense plug-in hybrid and Toyota C-HR hybrid, which are likely to hold more appeal for company-car drivers due to their low CO2 emissions.
Kia Stonic MPG & CO2
The previous entry-level 1.4-litre petrol engine has been retired, replaced by the cleaner and more efficient 1.0-litre turbo petrol. In 99bhp guise, it has official figures of up to 49.6mpg and CO2 emissions of 129-130g/km, placing it in a midrange Benefit-in-Kind (BiK) band.
Thanks to its mild-hybrid technology, the more potent 118bhp version is even more economical, returning up to 51.4mpg, with emissions of 125-129g/km. Its 48-volt mild hybrid system recovers energy that would usually be wasted while decelerating, storing it in a small battery to assist the engine under acceleration.
Previously, a diesel 1.6-litre CRDi engine was available, and capable of 56.5mpg with CO2 emissions of 130g/km, but this has now been phased out.
The entry-level 1.0-litre Stonic is liable for the standard VED (road tax) rate after the first year, while the more powerful mild-hybrid engine qualifies for the discounted VED rate as it’s classed as an ‘alternative fuel vehicle’ (AFV).
Kia benefits from relatively low insurance groups, giving its cars some extra appeal for younger drivers. The Stonic is rated in groups 11-14 depending on exact specification, while the Renault Captur occupies groups 8-19 and the Stonic compares favourably with the Peugeot 2008 in groups 13-23.
Kia is one of the best manufacturers in the business when it comes to the warranty offered with its new cars. The Stonic is covered for seven years/100,000 miles, offering buyers great peace of mind.
Kia servicing costs are reasonable. Petrol Stonics need a service every 10,000 miles or 12 months, with diesels needing attention every 20,000 miles or 12 months.
Kia offers a ‘Care-3’ service pack that costs £300 and covers you for the first three services. For an extra £30, you can get the car’s first MOT included, and for £600 you can cover the cost of the car’s first five services.
