The K4 shares the same 2.0-liter naturally aspirated inline-four engine from the outgoing Forte, which produces 147 horsepower and 132 lb.-ft. of torque. Drivers looking for more power can opt for the GT-Line Turbo. This variant boasts a 1.6-liter turbocharged four-cylinder engine, delivering 190 horsepower and 195 lb.-ft. of torque. Despite this, the powertrains of the 2025 K4 don’t break new ground compared to rivals like the Honda Civic and Toyota Corolla. 

Inside, the K4 offers a tech-filled cabin with a 12.3-inch touchscreen, a 12.3-inch digital gauge cluster, and a 5.0-inch climate control interface, all standard. Wireless Apple CarPlay® and Android Auto™ come standard, making connectivity a breeze. For those who love added convenience, the GT-Line comes with heated front seats, and buyers can upgrade to premium features like a wireless phone charger and Harman Kardon® audio system. 

The K4 promises to be the brand’s most affordable model but faces tough competition from other compact sedans.

Under the hood, the car’s base engine has been upgraded to a 2.5-liter naturally aspirated inline-four, producing 191 horsepower and 181 lb.-ft. of torque. This more robust engine replaces the previous turbocharged 1.6-liter unit, offering better performance for drivers. However, some may miss the turbo’s sporty feel, especially since Kia still hasn’t introduced a hybrid version of the K5, a feature that competitors like the Honda Accord already offer. 

Inside the cabin, the K5 continues to impress with a 12.3-inch touchscreen, wireless Apple CarPlay® and Android Auto™, and new safety features like adaptive cruise control and parking sensors.

Drivers will appreciate the new HVAC touch panel and improved cupholders for convenience. Overall, the 2025 Kia K5 delivers a winning combination of style, power, and technology, though it might not be as sporty as its bold design suggests. 

The vehicle’s hybrid engine pairs a 1.6-liter turbocharged four-cylinder with an electric motor, generating 242 horsepower and 271 lb.-ft. of torque. This setup offers better fuel efficiency than the standard V6, making the Carnival an attractive option for families who want the space of a minivan without sacrificing fuel economy. 

On the outside, the Carnival gets a refreshed look with a redesigned front grille, updated taillights, and new wheel designs. Inside, the tech upgrades continue with a dual 12.3-inch screen setup that runs on a new operating system capable of over-the-air updates. This tech-savvy minivan also has seven USB-C ports, a digital rearview mirror, and an available head-up display. 

Despite its updates, the Carnival has areas that need further focus, particularly with the standard V6 engine, which can feel unrefined under heavy load. Additionally, the rear seats might feel stiff for some passengers.
