Kia K5 vs Kia Optima

Kia has updated the stylish 2025 K5 with new exterior lighting, revised front and rear styling, and redesigned wheels. The only turbocharged version is now the GT sports sedan; other K5 models have a 2.5-liter four-cylinder with less real-world driving punch than the previously-standard turbo four. New technology, redesigned dashboard controls, and more standard features are also on the menu, and Kia’s family car remains a good value.

Verdict: Unfortunately, the 2025 Kia K5 still doesn’t offer a hybrid powertrain like its corporate cousin, the Hyundai Sonata, does. It’s also less enjoyable to drive, thanks to this year’s engine swap. However, the new tech impresses, the K5 remains stylish and comfortable, and it costs less than some rivals.
