The Kia Rio is a promising small car with price on its side. Its turbocharged engines are perfectly competent around town and at motorway speeds. We’d stick to the 2 trim because it adds AEB, gives you access to our favourite engine, has plenty of equipment and still keeps the price competitive. The mild-hybrid engine is only available as part of grade 3 trim, which pushes the Rio’s price too close to more desirable and efficient rivals such as the Honda Jazz and Toyota Yaris hybrid.
