Kia Rio (2017-2023) Pros and Cons

Pros	Cons
As sensible and practical as superminis get	A bit of a yawn to look at
The seven-year warranty is class-leading	Slow 1.2-litre petrol engine
Perky 1.0-litre turbo engines	Nothing like as much fun as a Ford Fiesta to drive

Quick Summary

The Kia Rio (2017-2023) is a straightforward, sensible, and practical supermini that prioritises reliability and user-friendliness over excitement. Though removed from the UK market in 2023, it remains an excellent secondhand buy. The interior is functional with well-laid-out controls, and the 325-litre boot expands to 1,103 litres with rear seats folded. Offering plenty of space for passengers and a comfortable ride, the Rio is easy to live with for families and commuters seeking dependable transport without fuss.

The Rio offers a wide range of engine options, with the perky 1.0-litre turbo variants being the most engaging to drive. Petrol versions achieve around 45mpg in real-world driving, whilst diesel models can reach 60mpg on longer runs. Servicing costs are relatively affordable, and many examples retain Kia's impressive seven-year/100,000-mile warranty. As a used car, it represents excellent value for budget-conscious buyers seeking a reliable, practical, and straightforward supermini with minimal hassle.

Best for: Budget-conscious buyers, those seeking reliable and practical transport, families and commuters, and drivers prioritising low running costs and warranty protection.

Not ideal for: Buyers seeking premium styling or badge appeal, those wanting an exciting driving experience, or drivers prioritising character over practicality.
