Engine Lineup and Driving Feel on the Kia K5 vs. Hyundai Sonata
Most 2025 K5 trims run on a 191-hp 2.5-liter four-cylinder engine paired with an eight-speed automatic and front-wheel drive, though all-wheel drive is optional. (That new engine replaces last year’s 1.6-liter turbo.) But if you want real performance, the GT trim steps things up with a turbo 2.5-liter that cranks out 290 horsepower and 311 lb-ft of torque.
The Sonata offers a similar 192-hp 2.5-liter base engine, and like the K5, it tops out with a 290-hp turbo-four. Front-wheel drive is standard, with all-wheel drive only available on the base engine.
Interior Comfort and Tech in the Kia K5 vs. Hyundai Sonata
Inside the K5, you’ll find clean design, solid materials (yes, even wood trim), and thoughtful touches—like a dead pedal for your left foot. Higher trims add ambient lighting, ventilated front seats, and a panoramic sunroof. The 12.3-inch infotainment screen is standard and runs wireless Apple CarPlay and Android Auto. Higher trims pair that with a 12.0-inch digital cluster and an available 12-speaker Bose system.
The Sonata goes for a wide-screen look, with two 12.3-inch displays housed under a single glass panel that spans two-thirds of the dash. Apple CarPlay, Android Auto, and wireless charging all come standard, and the Bose stereo is also optional.
So, Which Sedan Should You Pick?
If you want sleek styling, smart new features, and that turbo punch in a sedan that’s priced just right—the 2025 Kia K5 is tough to beat. It’s got everything you need in a midsize daily driver with a premium feel. The Sonata’s still a strong pick, but the K5 just feels more current.
