The Kia Rio is a supermini rival to the Ford Fiesta, and has an attractive exterior style, abundant interior space and an excellent range of engines, comprised of two diesels (1.1-litre and 1.4-litre) and two petrols (1.25-litre and 1.4-litre). The smaller 74bhp diesel actually offers one of the lowest CO2 emission figures of any non-electric car in the UK at 85g/km, making it exempt from road tax. It also returns a truly excellent 88mpg in fuel economy. You can get the Rio in both three and five-door versions, both sporting Kia's wide grill and distinctive creases along the sides. As a whole package, the Rio still stands out from the crowd, even though it has been available for a couple of years. The Kia Rio comes in three main specifications – entry-level 1, mid-range 2 and top-of-the-range 3. You get to choose between three metallic colour schemes or solid white on entry-level models, with the 2 spec also getting an extra metallic colour, and the 3 offered in a total of six colours.
