The 2025 Kia K4 at Jim Butler Kia of St. Louis is making waves. This isn’t just a new model name replacing the long-standing Forte; it’s a complete reimagining of what a small sedan can be. With sharp styling, a roomier interior, and turbocharged performance under the hood, the K4 is Kia’s boldest move yet in the compact segment.
Goodbye Forte, Hello K4
In keeping with Kia’s new naming convention, the K4 replaces the Forte with a confident, contemporary look that immediately catches the eye. With sculpted lines, an upright profile, and design cues that borrow from high-end European influences, the K4 brings a surprising level of style to the compact class.
The GT-Line Turbo trim elevates the look even further with sporty front and rear fascias, sleek black trim, and 18-inch wheels that tie the whole package together. It's a head-turner in the best way—and that's not something people usually say about small sedans.
Space-Age Interior with Real-World Comfort
Step inside, and the K4 continues to impress. The GT-Line offers 10-way power-adjustable front seats with a futuristic design that wouldn’t feel out of place in a sci-fi movie. The dashboard is dominated by a sweeping digital layout, featuring a responsive 12.3-inch touchscreen and an intuitive interface that’s easy to personalize. A separate screen handles climate controls, while physical buttons make key adjustments a breeze.
Compared to the outgoing Forte, the K4 is noticeably more spacious. Rear-seat passengers will appreciate the extra legroom, and the trunk is generously sized for everything from daily errands to weekend getaways.
Real-World Performance, Everyday Fun
Under the hood, the GT-Line Turbo packs a 1.6-liter four-cylinder engine paired with an eight-speed automatic transmission. With 190 horsepower and 195 lb-ft of torque, this setup delivers responsive acceleration and confident highway merging—perfect for navigating I-64 or beating traffic on I-70.
While it's not built for backroad canyon carving, the K4 handles with composure and grace. Sport mode tightens the steering, giving drivers a little more engagement without sacrificing comfort. And with standard driver-assist features like lane keeping, forward collision avoidance, and available blind-spot cameras, the K4 is as smart as it is stylish.
Tech-Forward Features with Everyday Appeal
Technology plays a central role in the K4’s appeal. Wireless Apple CarPlay and Android Auto make it easy to stay connected on the go, and the available Harman Kardon sound system delivers crisp audio for your favorite playlists or podcasts. There's even a clever pass-through in the rear seat for longer cargo—perfect for road trips or golf clubs.
Every detail inside the cabin is thoughtfully designed with driver and passenger comfort in mind. Even during long commutes or errand-heavy weekends, the K4 proves itself to be a relaxing, well-equipped ride.
Whether you're cruising through downtown, navigating Forest Park, or heading west for a weekend at the Lake of the Ozarks, the K4 is versatile enough to handle it all. The increased cabin space and comfortable ride quality make it an ideal choice for commuters and small families alike—especially those who value elevated design without stepping into the luxury price bracket.
Smart Safety That’s Always On Duty
Safety is at the forefront of the K4’s value proposition. Alongside advanced driver assistance features, Kia’s available Technology Package adds conveniences like a surround-view monitor and the brand’s innovative blind-spot view monitor—perfect for crowded city streets or busy parking lots around West County Center. These thoughtful touches not only make driving easier, they also help protect you and your passengers on every journey.
Efficiency Meets Everyday Utility
Fuel efficiency remains a highlight for this compact sedan, with EPA-estimated numbers that make it easy on the wallet whether you’re filling up in the city or heading out on a road trip. With impressive mileage figures and a deep, practical trunk, the K4 handles both routine errands and spontaneous adventures with ease. It’s proof that you don’t have to compromise efficiency to enjoy premium design and modern features.
Backed by Kia’s Industry-Leading Warranty
As with every Kia, the K4 comes with one of the best warranties in the business—another confidence-boosting reason it’s such a smart buy. For St. Louis-area shoppers who expect long-term value and peace of mind, this coverage ensures the K4 delivers not just up front, but for years down the road.
