The K4 serves as Kia’s replacement for the Forte. The new car is slightly larger than before, with increased passenger and cargo space. But what really struck us is how good this car is for the price, especially when you consider that the average new car costs twice as much as the K4 LXS we tested. Unlike many less-expensive models, which come with glaring tradeoffs for the savings, the K4 has few flaws.

Model History

2025-Present

Current Generation

The K4 is slightly larger than the Forte it replaced, giving it more passenger and trunk space. The powertrains are similar, with the base configuration being a 147-hp, 2.0-liter four-cylinder engine with a continuously variable transmission. The sportier version gets a 190-hp, 1.6-liter turbocharged four-cylinder with an eight-speed automatic transmission. The K4’s comfortable ride punches above class standards, and it feels responsive through corners. The cabin is roomy for its class, with comfortable seats front and rear, plus a huge trunk. But the car’s low stance makes it a chore to get in and out, and the hidden rear door handles are a nuisance. There are tech features that stand out in the class, like the available multi-screen display that spans 30 inches, serving the instrument cluster, climate controls, and infotainment system. Other available upgrades include a Harman Kardon premium audio system, heated and ventilated front seats, and a large sunroof. All K4s have wireless Android Auto and Apple CarPlay. The K4 packs a full roster of active safety features, and there are numerous upgrades that are more typically found on luxury models.
