Summary
The Kia Rio is a small supermini-class five-door hatchback. The current model is the fourth-generation Rio, which arrived in the UK in early 2017. It shares most of its underpinnings with the Kia Stonic small SUV and the Hyundai i20 hatch.
The Rio is currently only available with a choice of three petrol engines. It was originally offered with a diesel engine as well, but this was discontinued due to declining European demand for small diesel cars.
The Kia Rio has received mixed reviews from the UK motoring media, and its overall Expert Rating of 56% (as of January 2024) places it firmly in the bottom half of the supermini class.
Most reviews have considered it to be competent but not in the same league as class leaders like the Ford Fiesta and SEAT Ibiza. Some titles, like Which?, have marked it down severely due to its sub-par three-star safety rating from Euro NCAP on the entry-level model.

“The Kia Rio has come on in leaps and bounds since the no-frills original, but the fourth-generation model isn’t a huge step on from the Mk3. It has merely average ride and refinement, and some hard, cheap-feeling interior plastics that all hurt its cause.”

“The Kia Rio offers good value and practicality, but it’s a safe pair of hands in a talented supermini class”

“While the new Kia Rio gets the basics right, it doesn’t do enough to stand out in the competitive supermini sector. We take issue with the unexciting design, mixed cabin quality and so-so ride and refinement. This diesel might sip fuel, but the 1.0-litre turbo petrol would be our choice in the range.”

“In isolation the new Kia Rio is a capable supermini, thanks to a neatly designed interior, range of efficient engines and big luggage area. Unfortunately, it’s entering a market with many excellent competitors that beat it in virtually every area, so it’s a tough one to recommend.”

“It’s all too easy to sound like we’re damning the Kia Rio with faint praise, but this really is a very decent car that does its job extremely well. It’s not quite class-leading in any way, but as an overall package, it has an awful lot to recommend it, and no major weaknesses.”

“It’s an even more practical, parsimonious and mature prospect than the car it replaces, and you could hardly ask for a more resolutely worthy, servile or grown-up supermini. Yet for all its functional virtue, the Kia Rio is made to look one-dimensional by the opposition.

“The Kio Rio is a well-equipped, cheap-to run and relatively spacious supermini. As a tool for getting from A to B, it’ll do the job nicely. Yet in class of such broad and varied talent, the Rio is overwhelmed.”

“It may not match rivals like the Ford Fiesta but the Kia Rio is a great-value, well-equipped and practical supermini. In top spec ‘3’ grade, it comes with all the kit you’d ever need. The 1.0-litre petrol engine is a fantastic unit, both around town and on the motorway, too.”

“The Kia Rio is a competent supermini, but because it doesn’t excel in any one area, it’s difficult to recommend over the competition.”

“Believe it or not, the Kia Rio supermini is the Korean brand’s best-selling model. The latest fourth-generation version wades into a congested field dominated by established rivals including the Ford Fiesta, VW Polo and Skoda Fabia.”

“The Kia Rio appeals not for its particular strengths, but in fact for its lack of weaknesses. That might not sound particularly interesting, but will make for a rewarding ownership experience backed up by Kia’s seven-year warranty.”

“The new Kia Rio is ideal for people buying cars. It’s easy to drive and easy to live with. But it’s rubbish for motoring journalists because there’s nothing to complain about. It just does everything as it should do. There are no quirky, annoying faults.”

“It might not have the all-round classiness and capability of the SEAT Ibiza or the dynamic sparkle of the Ford Fiesta, but the Kia Rio is a very capable hatchback that does everything well enough. Factor in the seven-year warranty and it’s a sound buy.”

“With each generation, the Kia Rio has got better to drive and far better finished, though even in its current guise it’s one of the more basic cars on the market, aimed at those who really value its combination of practicality, affordability and the peace-of-mind offered by its seven-year warranty.”

“The Kia Rio might not be the most fun car to drive in its class, or as comfortable as some rivals, but it scores well most other areas, whether it’s in the space on offer, the low running costs, excellent reliability record, or value for money.”

“The Kia Rio is a promising small car with price on its side, while its turbocharged engines are perfectly competent both around town and at faster motorway speeds. However, rivals such as the Ford Fiesta ride much better and are overall more fun to drive.”

Note on safety
As of May 2020, the entry-level Kia Rio ‘1’ earned a three-star rating from Euro NCAP in standard form. Models from specification ‘2’ and upwards are fitted with additional safety equipment as standard, which is an additional £350 option on the ‘1’. This additional equipment lifts the Euro NCAP safety score to five stars.
This rating has since expired, as the car no longer meets the increasing standards for a three-star rating.

Reliability score
All data based on MotorEasy average workshop costs for extended car warranty claims
The Kia Rio has an above average warranty reliability score, according to extended warranty data provided exclusively to The Car Expert from our partner, MotorEasy.
The key Rio complaint refers to the car’s braking system, which costs a pretty affordable £170 to fix on average. Very expensive engine issues have also been reported though – while they are rare the average fix cost is close to £3,700. That’s very high for a car of this size.
However, we only have 24 warranty claims on file, which is a small amount. Not only are other superminis like the Vauxhall Corsa more reliable according to MotorEasy, but they have a much larger selection of reported warranty claims, which provides a more accurate breakdown of what is likely to cause issues during the course of ownership.

Running costs for the Kia Rio range are a pretty affordable, according to data provided exclusively to The Car Expert by our commercial partner, Clear Vehicle Data.
Though we don’t current have the full picture – with no maintenance and service cost estimates – the car’s fuel consumption which ranges from 44mpg to 54mpg is commendable, and its insurance premiums should be very low.
