Compact Powerhouse: K4 Demonstrates That Size Doesn't Limit Capabilities
The 2025 Kia K4 compact sedan has been crowned as the winner of the prestigious Wards 10 Best Interiors & UX award. This recognition is chiefly due to the K4's class-leading digital display technology, user-friendly interface, and roomy, comfortable interior design.
The K4 boasts nearly 30 inches of seamless digital display, combining large touchscreens and a digital instrument cluster. This smart, driver-friendly control layout enhances usability and visual appeal. A 12.3-inch touchscreen is standard across all trims, with available dual 12.3-inch displays plus a separate 5-inch climate control screen in premium trims.
Wireless Apple CarPlay and Android Auto integration and an AI-powered voice assistant ensure seamless, safe smartphone connectivity without cables. The K4's spacious cabin, particularly class-leading rear legroom, is supported by a fastback/hatchback design that offers over 23 cubic feet of cargo space and flexible seating.
Safety-oriented UX features include a 360-degree camera, blind-spot alerts, lane keeping, and up to 29 driver assistance features. These are integrated in a way that balances convenience with security without overwhelming the driver. Additional upscale comfort features, such as heated and ventilated seats, a Harman Kardon premium sound system, and a wide panoramic sunroof, contribute to the luxurious feel within a compact sedan footprint.
The K4's interior aesthetic and tech features mark a progressive update from the old Kia Forte. The cabin uses glossy gray trim instead of black, which is more forgiving in hiding dust than piano black. The K4 has been lengthened and widened for 2025, giving the sedan the largest footprint in the compact segment.
The K4's interior is noted for its look, functionality, and creature comforts that match or exceed those of cars costing much more. The GT-Line test vehicle of the Kia K4 has a heavier emphasis on white than typical in black and white interiors. The interior features quality SynTex faux leather.
The K4's interior also offers practical features, such as adjustable and large cupholders with a half-round divider that can be tucked away. The sedan is equipped with an ambient lighting system with dozens of shades to choose from. A bold and colorful animation at startup and shutdown adds a touch of style.
The K4's interior is designed with driver safety in mind, featuring a good amount of physical switchgear. Easy access to navigation and search commands, with an intuitive and clean layout, further enhances the user experience. Standard ADAS features include stop-and-go adaptive cruise control, auto hold, surround-view, and blindspot-view monitors.
In the words of judge Gary Vasilash, the K4's interior is a class or two above what many vehicles have, and adding $10,000 to the sticker price, it is still one of the most impressive interiors out there, period. The 2025 Kia K4 compact sedan sets a new standard for compact sedans, earning its award for interior and UX excellence.
