While most automakers are busy rolling out electric vehicles, Kia’s still putting fresh thinking into its gas-powered cars, especially the ones that are affordable. The 2025 Kia K4 is proof. It’s a brand-new nameplate, built from the ground up to replace the Forte entirely.

3 Highlights of the 2025 Kia K4

1. Outside Design

Over the last few years, Kia has been quietly putting out some of the best-looking cars on the road, and the K4 keeps that streak going. The first thing Kia did with the sedan was stretch it out. It is about three inches longer and two inches wider than the Forte. That extra space gives rear passengers almost 2.5 more inches of legroom, which happens to be best in class.

From there, the design gets a lot more expressive. There’s a fastback-style roof, flared rear arches, a sharp nose, and the rear door handles are hidden in small triangles built into the window trim. The side profile has a crease that dips low up front, runs clean through the door, and lifts again at the back. It’s easy to miss until the light hits it and makes it pop.

2. Interior

The K4’s interior mixes old-school charm with the tech-forward touches Kia is known for. You’ll notice a few traditional details right away, such as a T-bar gearshift on the console, physical buttons above and below the central air vents, and a rotary controller for operating the screen. Even the drive mode selector is friendly. It’s a big, easy-to-reach button right at the base of the steering wheel, so your eyes can stay on the road.

You’ve got a 12.3-inch digital gauge cluster, another 12.3-inch screen running the infotainment, and a smaller 5-inch display just for climate control. On some trims, all that screen space, about 30 inches in total, is tucked neatly under one panel. Lower trims come with cloth seats, while moving up gets you synthetic leather, standard seat heating, and optional ventilation.

3. Powertrain

Most K4 models are powered by a 147-horsepower 2.0-liter engine with front-wheel drive and intelligent variable transmission (Kia’s version of the CVT). This setup is easy on fuel, with EPA ratings of 30 mpg in the city and 40 mpg on the highway.

For drivers who want something with a bit more punch, there’s also a turbocharged 1.6-liter engine. It pushes out 190 horsepower and 195 lb-ft of torque through an eight-speed automatic transmission. Suspension setup depends on the trim. LX through EX models ride on a torsion beam, whereas the GT-Line and GT-Line Turbo switch to a multi-link design.

There’s a lot to like about the new K4, but the best way to know if it’s for you is to get behind the wheel. Stop by Kia of Marin in Novato, CA, and take it for a test drive.
