As mentioned above, the 2021 Kia K5 functions as a complete redesign of the previous Optima model, most prominently in terms of looks. Inside and out, the Kia K5 midsize sedan prioritizes a sporty style with a fastback-inspired design lifted from the Stinger to highlight its improved performance. Elsewhere, the available GT-Line and GT trim of the Kia K5 further bolster style and comfort for an incredible driving experience.

The 2020 Kia Optima comes equipped with a baseline 2.4L inline 4 engine that produces up to 185 horsepower and 175 lb-ft of torque. Meanwhile, the baseline engine of the new Kia K5 is rated at 180 horsepower and 195 lb-ft of torque. Additionally, an upgraded engine option improves that to 290 horsepower and 311 lb-ft of torque. Additional performance highlights of the 2021 Kia K5 include available traction-enhancing AWD for all-weather performance, an 8-speed dual-clutch transmission option, and the Sport+ driving mode.

Beyond looks and power, the 2021 Kia K5 model also features a boatload of brand-new and upgraded technologies for its drivers to make use of. For comfort, entertainment, and safety purposes, some of the many options include standard Kia Drive Wise driver-assistance features, wireless Android Auto™ and Apple CarPlay® compatibility, wireless smartphone charging, remote engine start, and Kia UVO link services.
