2025 Kia K4 Quick Guide | Latest Features, Trims, Colors

  
The 2025 K4 at a Glance

K4 Overview Kia continues to refresh its lineup and sedan naming convention with the all-new K4. Replacing the Kia Forte, the K4 slots into the lineup below the K5. With the subcompact Rio ending production, the K4 is now the entry point into Kia's sedan lineup.

The K4 compact sedan is longer and wider than its predecessor. Vertically oriented LED headlights and taillights give the K4 a new look that aligns with the updates to the 2025 Kia K5. Up front is the signature Tiger Nose grille and updated fascia that gets a distinctive look on the GT-line trims. The K4 has the look of a fastback but, like the K5, it features a conventional trunk rather than a hatchback.

Significant updates are found in the K4's cabin, where a new display screen measuring almost 30 inches houses the digital driver's display and updated infotainment system. The increased dimensions translate to a roomier interior, giving rear-seat passengers more legroom and headroom than in the outgoing Forte.

The fresh styling inside and out, as well as an available turbocharged engine, make the K4 a strong competitor in a crowded compact car segment.

What is the Interior Like in the 2025 K4?

To answer your question in simple terms: stunning! 
The new Kia K4 gets a significant interior upgrade compared to the outgoing Forte, giving the compact sedan a premium vibe. A large display screen incorporates the driver's gauge cluster and infotainment touchscreen display, all nicely integrated into the dashboard. The clean design features minimal physical controls, with shortcuts to the home screen, navigation, and media placed below the screen. Climate functions are kept separate for easy access, and a volume knob is a welcome addition.

Stylish front seats, with available heating and ventilation, are trimmed in Medium Gray on LX, LXS, and EX trims, with the option of Slate Green on the EX. GT-Line trims feature a stylish two-tone Onyx and Off White combination.

The K4's larger dimensions provide more legroom and headroom in the back seat compared to the Forte. The K4's 38 inches of legroom is considerably more than that found in its competitors.

How does the 2025 K4 Handle on the Road?
The engines in the new Kia K4 carry over from the Kia Forte, with a 2.0-liter four-cylinder engine as the standard powertrain, putting out 147 horsepower and 132 pound-feet of torque. A continuously variable transmission (CVT) is also standard.

The K4 GT-Line Turbo upgrades to a 1.6-liter turbocharged engine that delivers 190 hp and 195 lb-ft of torque. Instead of the CVT, the turbo engine is paired with an eight-speed automatic transmission; no manual transmission is available. The horsepower rating is slightly lower than that of the turbo engine in the Forte, but the torque remains unchanged.
