The Kia Rio is a practical and affordable supermini with a long seven-year/100,000-mile warranty If competes in an important class, against rivals like the Volkswagen Polo, Ford Fiesta, Vauxhall Corsa and SEAT Ibiza There are four engines to choose from, including a 1.0, 1.25 or 1.4-litre petrol and a 1.4-litre diesel The Rio adopts Kia's latest styling cues, as seen on models including the popular Kia Sportage SUV The top performers are the 1.0-litre turbocharged petrols with 99 and 118bhp, getting from 0-62mph in around 10 seconds It might have a fairly conservative design, but LED daytime running lights help give the Rio a modern look The previous Rio had a dated dashboard, so the new model is a big improvement in design and quality A seven-inch infotainment system and sporty steering wheel are two highlights which lift the interior Every Rio gets five doors, improving access to the accommodating rear seats. Leg room and headroom are good too The Rio's 325-litre boot is a real advantage, trumping the VW Polo, Ford Fiesta and Vauxhall Corsa Flipping the rear seats forward increases load space to 980-litres, but there's a noticeable hump to lift objects over Trim levels are called 1, 2 and 3, with even the 1 trim getting air-conditioning and Bluetooth connectivity Many buyers will opt for the 2 trim, thanks to its DAB radio, reversing camera, rear parking sensors and cruise control The 3 trim gets faux-leather upholstery and the seven-inch infotainment system with Apple CarPlay and Android Auto Advanced safety features like Autonomous Emergency Braking (AEB) are standard with 2 and 3 trims The Rio makes sense among motorists who don't get emotionally attached to their cars The Kia Rio is likely to serve as reliable family transportation It's an attractive car if not one with a particularly imaginative design Its high level of standard equipment means it'll be easy to live with day-to-day It's simple mechanical nature is likely to prove reliable, too. Perhaps the promise of seven-year's peace-of-mind is the Rio's star attraction
