2021 Kia K5 vs 2020 Kia Optima

Serving Morrow, GA

The incoming 2021 Kia K5 has replaced the outgoing 2020 Kia Optima. While these are both midsize sedans that you may expect to be relatively comparable, the reality is that they have stunning differences from end to end. Our Kia Atlanta South sales reps are always happy to answer your questions as you compare the possibilities available for your next sedan purchase.


The 2020 Optima is offered with three powertrains that all come with front-wheel drive and an automatic transmission. These are a 2.4-liter engine that produces 185 horsepower, a turbo 1.6-liter engine that delivers 178 horsepower, and a 245-horsepower, 2.0-liter engine. On the other hand, the 2021 Kia K5 has two engine options paired with an eight-speed auto transmission and either front-wheel drive or all-wheel drive. The K5’s powertrains are a 180-horsepower, turbo 1.6-liter engine, and a 290-horsepower, turbo 2.5-liter engine.


The 2020 Kia Optima is easy on the eyes with a sporty profile, low ground clearance, and electrifying LED headlights. The 2021 Kia K5 takes athletic styling to a new level with a power-minded hood with a sharp, defined curve and a longer, leaner profile. The K5 also has horizontal accents through the lower front fascia, a reshaped grille, and stunning headlights that are highlighted by an orange ribbon of accent lighting.


At the lower trim levels, the interior features in the Optima and the K5 are comparable. You will find more differences as you compare higher trim levels. For example, only an 8-inch touch display screen is available in the Optima, and the higher K5 trim levels take this up to 10.25 inches. The Harman Kardon premium sound system in the 2020 Optima is upgraded to a Bose sound system with a few extra speakers in the 2021 K5.
