Summary


The Kia Stonic is a small SUV/crossover based on the Kia Rio hatchback. It was launched in late 2017 and is the smallest crossover in the Kia range.

The Stonic has received mixed reviews from the UK motoring media, with an overall Expert Rating that puts it in the midfield of its class.

One of the reasons for an abnormally high variation in scores is the Stonic’s safety rating. The entry-level models only received a three-star safety rating from Euro NCAP, while the top-end models get more safety kit (optional on the base models) and score five stars. Some sources penalise this more than others, so the Stonic gets a four-star rating from What Car? yet a “Don’t Buy” recommendation from Which?

Other than stiffing buyers of the base models when it comes to safety, the Kia Stonic generally gets praised for its driving dynamics and Kia’s standard seven-year warranty. However, it is criticised for poor boot space and not being as good as the Kia Rio hatchback it’s based on.

The diesel engine version has been discontinued along the way, in line with the world’s overwhelming rejection of diesel power. Now the only engine available is a petrol unit, either with or without mild hybrid assistance. As of January 2024, the Kia Stonic has an Expert Rating of 57%.

Note on safety rating

The Kia Stonic is currently available in four trim specifications in the UK. The two lower-spec models have a more basic safety specification than the higher-spec models, and received a three-star score from Euro NCAP. The more expensive models have additional active safety (accident avoidance) equipment, which gives them a five-star rating.

The Kia Stonic is a pretty affordable car to own and run, according to whole-life cost numbers provided exclusively to The Car Expert by our data partner, Clear Vehicle Data.

Diesels will always be the more fuel efficient choice, but petrol models also offer decent fuel economy. Insurance premiums are low, and service and maintenance costs over the course of five years of ownership should be excellent too.
