The Rio is a small front-wheel-drive car that serves as Kia's entry-level model in the United States. Available in a four-door sedan and a 5-door hatch, the Rio uses its smaller proportions and advanced powertrain technologies to achieve fuel economy ratings of up to 29/37. Similar in size to the Ford Fiesta and Chevrolet Sonic, the Rio 5-door is over 10 inches shorter than Kia's next model, the Forte. Like other models in the segment, the Rio advertises a low starting price, but omits common conveniences. The Rio does however include 4-wheel disc brakes on all models, which are commonly omitted in this segment to save cost. The Rio EX with the optional Convenience package includes all power equipment, the UVO infotainment system, alloy wheels, and a backup camera for about $18,000. The handsomely styled Rio may be one of the best values on the market.

Idle Stop and Go (ISG) option added.
