Yet like every new car from the Korean automaker, the 2015 Kia Rio packs style, features and value. This 5-passenger subcompact starts under $15,000 and boasts fuel economy up to 37 mpg, which makes it attractive to younger drivers and buyers on a budget. Equally impressive is that, like every other new Kia, the Rio includes a powertrain warranty good for 10 years/100,000 miles. The 2015 Kia Rio continues to remind us that subcompacts have come a long way from their econobox days.
