The Dodge Aries was a series of mid-size cars introduced for the 1981 model year. The Aries was also sold as the Plymouth Reliant, and was available as a sedan, station wagon, or coupe. Dodge built the Aries using the K-Body platform, leading to these cars being known as the Aries K. A wide range of inline four engines were available on the Dodge Aries, which was produced until 1989.
