The 2025 Kia K4 replaces the Forte as the Korean automaker's compact sedan entry. The range-topping GT-Line is available with an optional 190-hp turbocharged 1.6-liter four-cylinder engine, and that's the version we tested here.
Whereas the naturally aspirated base engine mates to a continuously variable automatic transmission, the GT-Line Turbo model comes exclusively with an eight-speed automatic.
Opting for the turbo four adds $2900 to the GT-Line's $26,345 base price.
The 2025 Kia K4 GT-Line Turbo hits 60 mph in a respectable 7.3 seconds.
Compared to the outgoing Forte, the 2025 Kia K4 is a head-turner—just maybe not always in a good way.
The 2025 Kia K4 GT-Line Turbo effectively takes the place of the Forte GT in Kia's lineup. That model made 201 horses from its turbo four and came with either a seven-speed dual-clutch automatic or a six-speed manual.
Opting for the 2025 Kia K4 GT-Line nets an independent rear suspension and a quicker steering rack relative to the torsion-beam-equipped K4 LX, LXS, and EX trims.
With limited lateral grip from its all-season tires, the 2025 Kia K4 GT-Line Turbo pulled a middling 0.83 g on our skidpad.
The eight-speed automatic is not the most responsive unit out there, and the 2025 Kia K4 GT-Line Turbo's 4.1-second 30-to-50-mph passing time reflects this.
