The K5 will offer a turbocharged 1.6-liter four-cylinder that makes 180 horsepower and 195 lb-ft of torque. This engine will be paired with an eight-speed automatic transmission and standard front-wheel drive, but all-wheel drive will be optional. The Korean-spec version we drove was front-wheel drive and demonstrated decent acceleration around town. However, it was less impressive at highway speeds, where it needed extra time to execute passes. Still, its dutiful transmission and well-insulated cabin helped ensure its engine noise never rose above a dull roar. Although it won’t be available right away, the sportier K5 GT will have a more powerful turbocharged engine. Its 2.5-liter four-cylinder will make 290 horses and 311 lb-ft. It’ll pair with an eight-speed dual-clutch automatic that Kia developed in-house, and the GT will wear sticky Pirelli P Zero summer tires that should improve its braking and cornering performance versus the regular models.
The EPA estimates the front-drive 2021 K5 will earn up to 29 mpg in the city and 38 mpg on the highway. Both those ratings fall within 1 mpg of similarly equipped rivals, such as the Nissan Altima and Toyota Camry. However, we don’t know how efficient the all-wheel-drive K5 or the more powerful GT model will be. Once all of its estimates are released, and we have the opportunity to test each model on our 200-mile highway route, we can evaluate their real-world mpg.
Inside, the K5 looks amazing for how much it’s expected to cost. The layout is both sophisticated and straightforward, and the cabin is appointed with attractive materials such as wood trim on the dash and doors. The model we drove boasted leather upholstery and a nicely contoured, leather-wrapped steering wheel. It also had a dazzling 12.3-inch digital gauge cluster with customizable themes and high-resolution graphics. The K5 also offers an array of upscale interior features, such as ambient interior lighting on the dash and doors, a head-up display, heated and ventilated fronts seats, heated rear seats, an air-purification system, a panoramic sunroof, and a wireless charging pad. While the driver’s seat feels high even at its lowest point, the comfortable spot for your left foot and floor-hinged accelerator are nice touches. The back seat also provides generous legroom, and the trunk looks to have plenty of space for luggage.
The 2021 K5 hasn’t been crash tested by the National Highway Traffic Safety Administration (NHTSA) or the Insurance Institute for Highway Safety (IIHS). The mid-size sedan will offer a variety of standard and optional driver-assistance technology. Key safety features include:
Standard forward-collision warning and automated emergency braking
Standard lane-departure warning and lane-keeping assist
Available blind-spot monitor and rear cross-traffic alert
