2025 Kia K4 vs 2025 Kia K5
The brand-new Kia K4 is a compact sedan known for its spacious interior, with class-leading second-row legroom. Its Connected Car Navigation Cockpit features two screens, giving you nearly 30 inches of viewable screen space, and this is just the front area.
The 2025 Kia K5 is a mid-size sedan. If it looks familiar and gives you that love-at-first-sight feeling, it is the Kia Optima rebranded for the 2021 model rollout, now its fifth generation of production.
