Aside from the roof and body panels behind the C-pillars, the two models are essentially identical mechanically.

Performance That Builds on Momentum

Most 2026 Kia K4 models are powered by a 2.0-liter four-cylinder engine producing 147 horsepower and 132 lb-ft of torque. It’s paired with a continuously variable automatic transmission (CVT) that sends power to the front wheels.

The range-topping GT-Line Turbo upgrades to a turbocharged 1.6-liter four-cylinder making 190 horsepower and 195 lb-ft of torque. This engine is mated to an eight-speed automatic transmission.

MPG Is A Strong Suite

0-60 MPH Times

The 2026 Kia K4 GT-Line Turbo, accelerated from 0 to 60 mph in approximately 7.1–8.1 seconds, which is a solid time for a compact in this class.
