2011 Kia Rio

The 2011 Kia Rio is a subcompact car known for its fuel efficiency and affordability. It came with two engine options: a 1.6-liter inline-4 gasoline engine producing 110 horsepower and 107 lb-ft of torque, and a 1.5-liter inline-4 diesel engine. The gasoline engine was available with either a 5-speed manual or a 4-speed automatic transmission, while the diesel was typically paired with a 5-speed manual. Owners generally appreciate the Rio’s good gas mileage and low price point. Common complaints include a somewhat underpowered engine, especially when fully loaded, and a basic interior lacking some of the features found in competing vehicles.
