2026 Kia K4: What's New, Specs & Features
Last updated August 4, 2026
The 2026 Kia K4 is a lineup-expansion year, not a full redesign. The main change is the arrival of the all-new K4 Hatchback, while the sedan mostly carries over.
About the 2026 Kia K4
4th-generation K4/Forte successor, second model year; the sedan carries over while the broader K4 family adds a hatchback for 2026.
Kia positions the K4 as a compact car that feels like a class-up choice: bold styling, a roomy rear seat, large-screen tech, and a generous list of driver-assistance features without moving into midsize-car size. It replaces the old Forte formula with something more expressive and more upscale inside, while still serving commuters, small families, and first-time buyers who want modern design and everyday practicality.
The 2026 K4 lineup ranges from the straightforward LX, with a 12.3-inch touchscreen and wireless Apple CarPlay and Android Auto, to trims focused on comfort or sportier road manners. EX adds heated synthetic leather seats and other cabin comforts, while GT-Line Turbo pairs a 190-hp turbo engine with an 8-speed automatic, dual 12.3-inch displays, a sunroof, and Harman Kardon audio.
