The Rio is Kia's entry in the supermini class and a great alternative to the Ford Fiesta. Introduced last year, it continues Kia's march upmarket and benefits from smart, contemporary styling, generous space inside and an appealing engine range – two diesels (1.1-litre and 1.4-litre) and two petrols (1.25-litre and 1.4-litre). Of these, the smaller, 74bhp diesel is one of Britain's lowest-emissions cars, at 85g/km, meaning you can enjoy road-tax-free motoring. It also delivers a claimed 88mpg iin fuel economy. Both five-door and three-door versions of the Rio are available. The Kia is now one of the most distinctive supermini's on sale today with its wide grill and distinctive creases down the sides. The overall effect is to give the car a look that makes it stand out from the crowd without being too odd to put some buyers off. All models come with a choice of three metallic colours and solid white, with the 2 spec getting the choice of another metallic colour, and the 3 offered in a total of six colours.
