The 2021 Kia K5 is a midsize sedan. It replaces the Optima in Kia's lineup, a vehicle that ranked high in the J.D Power 2020 Automotive Performance, Execution and Layout (APEAL) Study despite its advancing age. It also replaces the Optima nameplate, presumably derived from the word "optimum" and used for 20 years on vehicles that mostly did more than less to live up to that promise.
As was true before, the new 2021 Kia K5 shares a platform, powertrains, and technology with the Hyundai Sonata, its corporate cousin. However, Kia puts its own spin on things with entirely different exterior styling and interior design, along with other details unique to this vehicle. It comes in LX, LXS, GT-Line, EX, and GT trim levels, and prices start at $23,490, not including a destination charge of $965.
