This guide breaks down what matters most when purchasing the 2026 K4 Hatchback, including performance, fuel economy, trim-by-trim features, interior, and more, so you can make the right decision for your needs.
When will the 2026 Kia K4 hatchback be available?
The 2026 Kia K4 Hatchback is expected to launch in the U.S. in late 2025. You'll find it in the EX, GT-Line, and GT-Line Turbo trims, each offering a special combination of performance and premium comfort.

2026 Kia K4 Hatchback Engine and Performance
Under the hood, the 2026 Kia K4 Hatchback combines efficiency and power. The standard 2.0L four-cylinder engine generates 147 horsepower and 132 pound-feet of torque and is combined with a smooth, continuously variable gearbox (CVT) built for everyday efficiency and comfort. For those seeking more power on the road, the 1.6L turbocharged four-cylinder produces 190 horsepower and 195 lb-ft of torque, mated to an eight-speed automatic transmission.
All 2026 Kia K4 Hatchback model levels come standard with front-wheel drive, but the GT-Line Turbo adds a sport-tuned suspension and quicker handling for a more enjoyable driving experience without compromising refinement.
2026 Kia K4 Hatchback MPG
The 2026 Kia K4 Hatchback, featuring its standard 2.0-liter four-cylinder engine, achieves an EPA-estimated 30 mpg in the city and 40 mpg on the highway.
