The Hyundai Sonata used to be a simple, comfortable, and affordable mid-size sedan. But then came a complete redesign for the 2020 model year. It brought unique and voluptuous new styling, a high-tech and upscale interior, and sportier driving manners — all while keeping prices in check.
But the next year, along came a closely matched challenger: the all-new Kia K5. Replacing the Optima, it’s a mechanical cousin to the Sonata and has many of the same virtues: style, performance, and value. We’ve tested both the K5 and the Sonata so we can evaluate their respective pros and cons, name a winner in each of eight categories, and share our top overall pick between these two Korean mid-size sedans. (Our test vehicles were 2021 models, but their only changes for 2022 were adjustments to their equipment lists and, on the K5, switching to the brand’s redesigned logo.)
