The 2021 Kia K5 is a new midsize sedan, formerly known as the Optima. For the past 20 years, the Optima has been attractive value and great value for money. With this redesigned 2021 model, Kia decided to go all-in and give it a new name. Highlights include boulder styling, new engine and transmission options, and all-wheel drive available.
The 2021 Kia K5 is offered in five trim levels: LX, LXS, GT-Line, EX, and GT.
