The 2026 Kia K5 is a midsize four-door sedan with a fastback roofline. It provides seating for five and cargo space in the trunk. It competes with vehicles such as the Honda Accord, Toyota Camry, and Hyundai Sonata, which offer comparable size, pricing, and features. The 2026 model carries over most elements from the 2025 mid-cycle refresh, including updated styling and a base 2.5-liter inline-four engine producing 191 horsepower and 181 pound-feet of torque. This engine pairs with an eight-speed automatic transmission and front-wheel drive, with all-wheel drive available on higher trims. The GT trim features a turbocharged 2.5-liter inline-four engine rated at 290 horsepower and 311 pound-feet of torque, along with an eight-speed dual-clutch transmission. Exterior updates for 2026 include revisions to the front fascia, grille, headlights, and fog lights.

The Kia K5 employs the Connected Car Navigation Cockpit system with dual 12.3-inch displays that form a continuous 24-inch curved panoramic panel for the instrument cluster and infotainment. These support wireless Apple CarPlay, Android Auto, voice controls, and Kia Connect for over-the-air navigation updates with real-time traffic. Driver assistance systems include Highway Driving Assist 2, which handles adaptive cruise control and lane changes; Blind-Spot View Monitor, which shows feeds on the gauge cluster; and forward collision-avoidance assist as standard equipment. The Kia Connect app allows remote checks of vehicle status, engine start, and service scheduling. Premium navigation maps and select connected services require paid subscriptions after the trial period.
