The 2025 Kia K4 is the brand’s boldest move in the compact sedan segment—replacing the Kia Forte and redefining what buyers can expect from an affordable, stylish, and tech-savvy car. With a radical design, an available turbocharged engine, and a host of premium features, the K4 aims to shake up the compact car market dominated by the Honda Civic and Toyota Corolla.

Whether you're a commuter, first-time buyer, or driving enthusiast, the K4 delivers a combination of style, performance, and value in a way that's uniquely Kia.
