2026 Kia K5 Review

The 2026 K5 lineup offers two distinct powertrain options designed to meet different driving preferences. LXS, GT-Line, and EX trims feature a naturally aspirated 2.5-liter four-cylinder engine producing 191 horsepower and 181 lb-ft of torque, paired with an 8-speed automatic transmission. This combination delivers smooth acceleration for daily driving while maintaining respectable fuel economy.

For performance enthusiasts, the K5 GT in Peoria AZ represents the pinnacle of the lineup. The same exhilarating power from a class-leading 290-horsepower 2.5-liter turbocharged engine returns for 2026, generating 311 lb-ft of torque. This powerplant transforms the K5 into a legitimate sports sedan that offers faster acceleration, from 0-60 mph, and better cornering performance than the 2024 BMW 530i. Independent testing confirms the GT variant can sprint to 60 mph in just 5.2 seconds and stop from 70 mph in 163 feet.

Every K5 comes standard with push-button start, electronic parking brake, and remote engine starter with climate control capability. The available all-wheel drive system on the GT-Line trim provides enhanced traction and control for challenging weather conditions. 

As the least expensive trim, K5 LXS models establish exceptional value with a comprehensive feature set. A prominent 12.3-inch touchscreen display anchors the dashboard, providing access to satellite radio, wireless Apple CarPlay, and Android Auto connectivity. The instrument cluster features a 4.2-inch Super Vision color display that complements the traditional gauges.

Standard comfort features include dual-zone automatic climate control, six-speaker audio system, and cloth upholstery with premium soft-touch materials. The cabin benefits from a Tricoat headliner and leather-wrapped armrest, creating an upscale atmosphere that belies the affordable pricing.

A third display screen positioned below the main touchscreen simplifies climate and audio adjustments with intuitive dial controls. This thoughtful design element enhances usability without adding complexity to the driving experience.

K5 GT-Line trims elevate the ownership experience with sporty styling and premium materials. Striking new 18-inch gloss black wheels give the exterior an ultramodern stance, while available red upholstery adds visual excitement to the cabin. The interior features an 8-way power-adjustable driver's seat wrapped in soft Syntex leatherette.

A distinctive D-shaped steering wheel bears the GT-Line logo. Leather wrapping extends to the center door trim and upper armrests. A redesigned center console incorporates a wireless charging pad and updated USB-C ports for modern connectivity needs.

Cold-weather comfort comes from heated front seats, while the available all-wheel drive system enhances capability for year-round driving confidence. The 12.3-inch touchscreen adds navigation functionality. Adding value, this allows for advanced Navigation-based Smart Cruise Control with Curve capability that automatically adjusts speed for upcoming road curvature.

K5 EX trims represent a luxury-oriented choice in the lineup, featuring a premium 12-speaker Bose audio system for your entertainment. Dual 12.3-inch displays include a curved digital instrument panel paired with the large touchscreen infotainment system.  A panoramic sunroof adds breezes during our moderate winters. 

Driver comfort reaches new heights with the power-adjustable seat featuring memory settings, a heated steering wheel, and heated front seats. Summer driving becomes more pleasant with ventilated front seats and rear air conditioning vents for passenger comfort.

Advanced safety technology includes a blind spot monitor with live video coverage, surround view monitor for enhanced visibility during low-speed maneuvers, and comprehensive parking distance warnings. The reverse collision warning system now includes automatic braking capability for added protection.

The flagship GT variant combines the most powerful engine with aggressive exterior styling cues. Simplifying the exterior, the "GT" logo on the brake calipers for the GT variant has been deleted for a cleaner appearance, while the quad-tip dual exhaust system signals serious performance intentions.

Interior appointments include rich black Syntex leatherette with GT logo embossing and distinctive green piping accents on the bucket seats. The D-shaped steering wheel also features the GT logo, reinforcing the performance-oriented character.

The GT trim adds luxury amenities like the panoramic sunroof, creating the perfect blend of performance and comfort for driving enthusiasts who refuse to compromise.

The 2026 K5 sets new standards for safety technology in the midsize sedan segment. Every trim level includes smart cruise control, lane following assist, and leading vehicle departure alert as standard equipment. The comprehensive driver attention warning and high beam assist further enhance the safety suite.

Forward collision avoidance operates through multiple scenarios, providing warnings and automatic emergency braking for vehicles, pedestrians, and cyclists. The system also monitors intersection safety during turning maneuvers using advanced camera and radar technology.

Parking assistance comes through the comprehensive warning system with sensors for both forward and reverse travel. The active rear cross traffic collision avoidance can intervene when backing out of parking spaces, while the safe exit assist helps prevent passengers from opening doors into oncoming traffic.

Despite its sleek exterior proportions, the 2026 K5 delivers impressive interior roominess. Total passenger capacity reaches 105.3 cubic feet, with an overall interior volume of 121.3 cubic feet – numbers that would be respectable in many SUVs.

Rear passengers enjoy 37.4 inches of legroom, adjustable headrests, and a center armrest for comfort during longer journeys. The EX trim adds rear air vents for enhanced climate control throughout the cabin.

Cargo capacity measures a generous 15.6 cubic feet in the trunk, expandable through the 60/40 split-folding rear seats. The smart-open trunk function provides convenient hands-free access when your hands are full.

As one of the favorites in its segment, the Kia K5 has also earned a spot on the Editors' Choice list for 2025 according to Car and Driver. When Kia introduced the K5 for the 2021 model year, it didn't just replace the Optima. It created a sedan good enough to become the top-rated midsize sedan, notes Edmunds. It's no wonder that the K5 is among the top-scoring midsized sedans, adds Consumer Reports.

K5 prices reflect exceptional value, starting at $27,390 for the LXS trim and ranging up to $34,890 for the fully-equipped EX. The 2026 Kia K5 is a practical, affordable, and high-tech midsize sedan with a sportier edge and more daring style than most of its rivals, according to Kelley Blue Book.

The 2026 Kia K5 continues to redefine what buyers can expect from an affordable midsize sedan. Whether you choose the value-packed LXS, the sporty GT-Line, the luxurious EX, or the performance-focused GT, each trim offers compelling reasons to consider this standout sedan. With its combination of striking design, advanced technology, comprehensive safety features, and competitive pricing, the K5 remains an excellent choice for Phoenix-area drivers seeking both style and substance.
