2021 Model Redesign Year
The K5 is pleasant, roomy, and fuel-efficient, and it handles securely. Its 2.5-liter four-cylinder engine is responsive and predictable but not particularly powerful. We got an impressive 31 mpg overall in our testing. The K5 aced all our braking and track-handling tests. The ride is firm yet comfortable. The GT trim comes with a 290-hp, 2.5-liter turbocharged four-cylinder mated to an eight-speed dual-clutch automatic.
The K5's cabin is nicely furnished with high-quality materials. The front seats are comfortable, and the rear seating space is roomy. We appreciate that it has a conventional gear selector, but the dual-function audio/climate panel is a nuisance. All-wheel drive is available, but unlike the similar Sonata, a hybrid version is not.

2021-Present

2021 Model Redesign Year
The K5 replaces the Optima. It shares a platform with the Hyundai Sonata, and is available with all-wheel drive. It also rides more comfortably than the Sonata. Handling is secure but not sporty. The roomy cabin has a traditional layout including a conventional shifter, but buyers unfortunately have to opt for the GT-Line trim or above to get a power driver's seat. The infotainment system is easy to use but only versions with the smaller screen have wireless Apple CarPlay and Android Auto.
Forward collision warning, automatic emergency braking with pedestrian detection, and lane keeping assistance are standard. Plus, there's also a driver attention monitor and rear seat reminder, but blind spot warning only comes on higher trims. The K5 gets a freshening, including a new 2.5-liter engine, that replaced the 1.6-liter turbo, for the 2025 model year.
