We got 33 mpg overall in our tests, which is good, but many nicer compact cars achieve or surpass that mileage. The Rio’s ride makes passengers feel every bump, and the car feels choppy when driving over uneven roads. At least the Rio has predictable, competent handling. The interior is basic, the front seats are short on support, and the rear seat is tight. The easy-to-use controls are a high point. But buyers must choose the higher S trim to get active safety systems, and it’s close to the price of much better, and larger, cars in the compact class. Recent changes included a new 1.6-liter four-cylinder engine, which is paired with a continuously variable transmission.
