The Rio comes as a sedan or hatchback and is a corporate cousin of the Hyundai Accent. Power comes from a 138-hp, 1.6-liter four-cylinder engine. It uses direct-injection technology and has a six-speed automatic, an unusual feature for the subcompact class. Fuel economy of 29 mpg overall with the hatchback in automatic isn't stellar for the class. The sedan version returned 30 mpg. The Rio feels solid when compared with some other subcompacts. The stiff ride and noisy cabin are typical among small cars. Higher trim models offer amenities such as heated seats and a rear-view camera, but they get pricey for this class. First-year reliability has been above average.
