Introducing the all-new 2025 Kia K4: Elevating the compact sedan with more room, segment-above tech and available turbocharged fun

“The all-new K4 advances Kia’s commitment to deliver sporty sedans with advanced technology and elevated performance,” said Steven Center, COO and EVP, Kia America. “Succeeding in the compact segment means overdelivering on the features that customers want, and the K4 is designed to exceed expectations.”

K4 Exterior Design: Bold Proportions

Stretched to all four corners with bold styling proportions, aligned with the tenets of Kia’s “Opposites United” design direction, the K4 makes a powerful, dynamic statement.

“By juxtaposing the K4’s fastback roofline and wide stance, we split the difference visually between the compact and midsize segments,” said Tom Kearns, chief designer, Kia Design Center America. “The creative tension that the Opposites United design language stresses allowed us to improvise on the traditional three-box form factor.”

With an overall length of 185.4 inches and width of 72.8 inches, the K4 is the widest and has the largest footprint in the compact segment. Rear passengers will enjoy the ride with a class leading 38 inches of leg room3 and class leading head room at 37.3 inches3. Standard, vertically oriented LED headlights and taillights take inspiration from the flagship EV9 and create pronounced edges through the lighting signature in the front and rear. Hidden rear door handles in the C-pillar emphasize the K4’s fastback proportions and draw attention to its swept-back daylight opening. A versatile, conventional trunk affords 14.6 cubic feet of cargo capacity.

Like other GT-Line models in the Kia lineup, exterior design flourishes distinguish the K4 GT-Line. Unique front and rear fasciae with gloss black accents, a satin chrome beltline, 18-inch alloy wheels, and gloss black mirror caps, window trim, and side sill. Small cube LED projection headlights, LED fog lights, and 18-inch alloy wheels add to the exterior of the K4 GT-Line Turbo.

K4 Interior Design and Technology: Seamless Connectivity

Kia Connect’s available voice assistant offers an easy way to access various vehicle functions. Say, “Hey Kia” to gain voice-control access to functions such as climate control and audio. Kia is working to enhance the Kia Assistant’s functionality with the power of generative AI to be able to provide information on many topics, such as stocks, sports scores, owner’s manual content, local points of interest and much more. The Kia Assistant is designed to listen for follow-up questions and to interact with the driver in a more conversational way.

The airy K4 interior is available in either Medium Gray (LX/LXS/EX) or Slate Green (EX), and the GT-Line models add Onyx and Off-White. Heated front seats are standard on K4 GT-Line and above, and ventilated seats as well as driver’s seat memory function are optional. A three-spoke steering wheel is unique to K4 GT-Line models.

K4 Powertrain and Engineering: Strong Choices

When it goes on sale in the United States, the front-wheel-drive K4 will offer two powertrain choices. The standard 2.0-liter engine produces 147 horsepower and 132 lb.-ft. of torque and is matched with an intelligently variable transmission (IVT).

An optional 1.6-liter, turbocharged engine sends 190 horsepower and 195 lb.-ft. of torque through an 8-speed automatic transmission. Steering wheel-mounted paddle shifters and sport pedals complete the sportier package. The K4 GT-Line Turbo delivers power smoothly at low speeds, responds quickly, and provides an engaging driving experience. Exclusive to the K4 GT-Line and GT-Line Turbo models is a multi-link rear suspension that adds lateral stiffness and compliance, for a sportier driving experience.

Attention was paid to reduce noise, vibration and harshness (NVH) through the use of an available acoustic windshield, and acoustic tires on K4 models with 18-inch wheels.
