2026 Kia K5 GT vs. GT-Line: What's the Difference?

Though similarly named and similarly equipped, the K5 GT-Line and K5 GT models do have some differences. The K5 GT-Line – available in FWD and AWD variants – offers a sporty appearance that turns heads when you arrive on the scene and a well-appointed cabin. The GT-Line FWD and GT-Line AWD are the second and third trims in the lineup. Upgrades from the base model include features such as Highway Driving Assist, SynTex seat trim, a 10-way power-adjustable driver's seat, a dual exhaust, and LED fog lights.

As the fourth trim in the lineup, the Kia K5 GT takes things even further. While it also boasts a more aggressive exterior design and improved amenities, it replaces the standard motor with a turbocharged engine. Complemented by a trim-exclusive sport-tuned suspension, the K5 GT stands out both on the interstate and on the track.

Athletic 2026 Kia K5 GT & GT-Line Power & Performance

The 2026 Kia K5 GT-Line engine is a spry 2.5-liter four-cylinder that pairs with an eight-speed automatic transmission, letting you effortlessly pick up speed as you merge onto the highway on your way to work. If you choose a 2026 Kia K5 GT-Line, horsepower reaches 191, and torque 181 pound-feet. As for the drivetrain, you can take your pick between FWD for an EPA-estimated 25/36/29 MPG (City/Highway/Combined) ¹ and AWD for improved traction, especially in inclement weather. The AWD variant renders an EPA-estimated 24/33/27 MPG (City/Highway/Combined).¹

For more power, let's look at the 2026 Kia K5 GT specs. What awaits under the hood is a key factor that sets this trim apart from the rest of the lineup: a turbocharged 2.5-liter four-cylinder engine that revs to the tune of 290 horsepower and 311 pound-feet of torque. Supporting this muscle is an eight-speed automatic dual-clutch transmission, and the steering-wheel-mounted paddle shifters let you take manual control when the mood strikes.

Don't think all that verve will leave you frequently stopping at the pump. This model achieves an EPA-estimated 23/33/27 MPG (City/Highway/Combined) fuel economy rating.¹
