The fourth-gen Optima, or as it’s known in Korea and China, the K5, has been with us since 2015. Last year, Kia introduced a facelifted version, so this should be enough for around two or three years, right?

This could help explain this test mule, as the automaker could already be working on a different iteration. Spied testing in its homeland not long ago, with the pics shared by Bobaedream, the car was wearing some heavy camouflage meant to hide its design details.

While the overhangs seem to be the same, there are some visual differences compared to the 2019 K5/Optima. The headlamps and taillights appear to have a different pattern, the rear license plate is now found in the bumper instead of the boot lid, a move that has led to other design changes, and the C pillars have a different shape.

Does this indicate that Kia has already started working on the next-gen model? Anything’s possible, including a more significant makeover of the outgoing one. And given the pace at which they have created this prototype, less than a year after the facelifted K5 broke cover locally, we wouldn’t be surprised if the next generation arrives as early as 2020.

We will definitely keep a close watch on the Korean market’s K5, as that’s where it will likely launch at first, previewing the Optima destined for other markets such as the U.S.
