Product Overview

The 5th-generation Kia Optima (K5) incorporates the powerful and bold design language of Kia Stinger. Built on the company's N3 platform, the K5 is longer, wider, and lower than ever.
In the US, the K5 features all-turbocharged inline-4 engine lineup with 8-speed automatic transmissions, including an 8-speed DCT for the highest-end 2.5 T-GDi model. AWD is available with the smaller 1.6 T-GDi engine.
The center piece of K5's exterior design is Kia's modernized "tiger face". Inside, a newly designed infotainment display seamlessly stretches into the instrument panel.

Reviewers from cnet have found:
Despite its questionable name, the 2021 Kia K5 GT is one of the most pleasant sedans you can buy today. The upgraded system on the 10.3-inch screen is not only dead simple to use, it's easy on the eyes. Features like forward-collision warning with pedestrian detection, lane-keeping assist and lane-departure warning are standard.
  • Gorgeous infotainment system
  • Powerful turbocharged engine
  • Comfortable ride
  • Lane-centering isn't as smooth as with other K5s

The 2021 Kia K5 takes the solid foundation of the Optima and adds an extra dose of style and performance. It's a well-executed midsize sedan, but it also faces strong competition. The K5 received a “Top Safety Pick+” rating from the Insurance Institute for Highway Safety.
  • Well-tuned chassis
  • Comfortable ride
  • Powerful engine
  • Lack of tech features
  • Lackluster performance
