2021 Kia K5 vs 2020 Kia Optima

Serving Columbus, OH

The Kia Optima is the midsize sedan that has given drivers plenty to love since its debut in 2000. Across two decades, the Optima has evolved through four generations. The popular Optima line officially ends with the 2020 model, and the K5 is the midsize sedan that will replace it in 2021. At Capital Kia, our goal is to help you learn about the exciting possibilities in our inventory today so that you can confidently pick out the sedan that is an excellent fit for you.


The 2020 Kia Optima is available with three powertrains. The entry-level Optima engine is a 2.4-liter, I-4 gas engine that will impress you with its 185-horsepower output. The top Optima trim level receives 245 horsepower from a turbo 2.0-liter, I-4 engine. In comparison, the 2021 K5 comes with two powertrain possibilities. The primary powertrain is a 1.6-liter, turbo I-4 engine that generates 180 horsepower. The K5's top trim level is equipped with a 290-horsepower, turbo 2.5-liter gas engine.


The Optima is easy on the eyes with low ground clearance and a sporty profile from end to end. The grille is perfectly integrated with multi-elemental, angled headlights accented by LED ribbons. The lower air vent displays a horizontal line of foglamp bulbs. The 2021 Kia K5 has more dramatic curvature throughout the prominent, defined hood. It also has low ground clearance with a layered look through the front end. Like the Optima's grille, the K5's grille extends across the nose and is integrated with the headlights. The K5's mesh has an edgy, modern look. The headlights show off a yellow LED ribbon that zags underneath the three bulbs. Two vertical bulbs sit underneath each headlight and serve as the foglamps.


The K5's interior design is noticeably different from the Optima's interior. Its dashboard has bold angles that create prominence throughout the center stack, and the console angles upward to enhance the innovative interior styling. While there are some differences in equipment across these two models on a trim-by-trim level, you may be thrilled to find that they both carry equipment that you are searching for in your next vehicle. This includes leather seating, a touch display screen, Apple CarPlay, Android Auto, USB ports, a standard or premium audio system, interior lighting, and auto climate management system, and other features.

At Capital Kia, we happily give you a convenient way to get familiar with the trims for both models. Through your in-depth and in-person comparison, you can find the perfect sedan that lives up to your expectations for style, features, and performance.
