K4 is Kia’s compact sedan nameplate launched as the successor to the K3. It was unveiled at the 2024 New York Auto Show as a global strategic model, marking the start of a new era for Kia’s entry in the compact car segment. The new nameplate reflects Kia’s latest design direction, with a more sculpted, fastback-inspired profile and vertical rear lighting that separates it from the older K3. Kia positioned it as a modern everyday car rather than a niche special edition, aimed at a broad global audience.
The K4 arrived as part of Kia’s broader shift in sedan naming, moving its mainstream passenger cars further into the “K” family seen across the brand’s lineup. In markets where it is offered, the model spans multiple body styles within the same continuous production era, including the original sedan and later hatchback derivative, but it remains one ongoing nameplate rather than a revived historical badge. Kia has also signaled additional powertrain expansion for the line, underscoring that the K4 is intended to be a long-term volume model.
Because the nameplate is still in production, there is no final model year to record yet.
