CoPilot's Take

The 2021 Kia K5 is a major advancement in the midsize sedan segment, offering an appealing blend of style, technology, and performance. The choice is also a K5 hallmark. From the efficient base trim to the high-performance GT variant, and with available all-wheel drive, there's a K5 to suit a wide range of preferences and needs.

However, potential buyers should consider some factors. While the sloping roofline contributes to the K5's attractive design, it can limit rear headroom for taller passengers. Additionally, some more advanced features are only available on higher trims, which may disappoint buyers looking for these technologies in more affordable models.
