Kia Rio

We got 33-mpg overall in our tests. That's good, but many more substantial compact cars achieve or surpass that mileage. The Rio's ride makes passengers feel every bump, and the car moves in choppy motions over uneven roads. We found that the Rio has safe, competent handling. The interior is basic, the front seats are short on support, and the rear seat is tight, but the easy-to-use controls are a high point. Buyers must opt for at least the S trim to get the active safety features. But the S trim is close to the price of a compact car, which is another reason not to buy the Rio. Recent changes included a new 1.6-liter four-cylinder engine, which is now matched with a continuously variable transmission.
