How Does the Kia K5 Differ From the Kia Optima?

The midsize Kia Optima has been a favorite of drivers from all over the Auburn, AL area. This compact crossover has gone through several iterations since it came onto the market in 2000. However, the Optima line ends with the outgoing 2020 model. At Kia AutoSport Columbus, we're excited to announce the Kia K5 is replacing it for 2021. Our objective here is to help you pick out a vehicle that suits your needs in the Opelika, Al area.


The 2020 Optima is available in the Phenix City, AL area with three drivetrains. The base Optima engine is a 2.4L 4-cylinder, which pumps out 185 horsepower 178 pound-feet of torque. The top-spec Optima model gets 245 horsepower from a 2.0-liter turbocharged engine.

The EPA estimates the 2.4-liter at 24/32 MPG on city/highway. The Optima tows up to 3,230 pounds.

In comparison, the K5 features two powertrains. The base engine is a 1.6-liter turbo, generating 180 horses and 195 pound-feet of torque.
