For decades, the Kia Rio served as a small, simple, dependable, and efficient form of transportation. Over the years, Kia has offered the entry-level car in four-door sedan and three- or five-door hatchback body styles — depending on its specification, some versions of the Rio also have a good sense of style. However, besides its competitive price tag, the Kia Rio relied primarily on a generous warranty to make its case with small-car buyers. Today, the fourth-generation Rio continues this tradition, available in sedan and hatchback body styles with a peppy four-cylinder engine rated to get good gas mileage.
