What is the Kia K4?
The K4 is Kia’s compact passenger car, offered as a sedan in North America and as a hatchback in Europe. Its fastback-inspired profile and distinctive lighting reflect Kia’s recent design direction. The model is part of Kia’s compact-car range; in North America, it follows the Forte.
The first generation, code CL4, began in 2025. The K4 sedan was introduced before the hatchback, and the body styles available vary by market.
