The Kia K5 debuted for 2021 as the replacement for the Optima mid-size sedan. The K5 name was borrowed from the South Korean version of the car, better aligning the U.S. version with Kia’s global offerings. A bold, fastback-inspired body design gave the K5 a more dramatic, sporty look compared to the outgoing Optima. Under the hood, the K5 offers a choice of turbocharged engines and (unlike the Optima) available all-wheel drive. The cabin has an upscale look that’s highlighted by a driver-focused dashboard layout and an available 10.25-inch touchscreen. The K5 represents a significant evolution of Kia’s mid-size sedan, moving it further upmarket to better compete with class leaders like the Honda Accord and Toyota Camry.
