The Kia KMX-90, originally named 기아자동차KMX-90, was a concept car from the South Korean manufacturer Kia Motors Corporation, presented as the first publicly shown Korean concept car. It appeared at a time when Kia, still only the third-largest carmaker in South Korea with an output of 134,000 passenger cars by 1988, was financially linked to Ford and Mazda and built models such as the Pride and Concorde derived largely from the Mazda 121 and 323, with the Pride also sold in the United States as the Ford Festiva.
The KMX-90 was a one-box design with no distinct front or rear deck, featuring a fully glazed upper body and angular styling. It stood out for its long gullwing doors, which also allowed easy access to the rear seats, and for wheel covers with air slits, with the front covers designed to swivel along with the steering. Downward-drawn flanks, front and rear aprons, and pop-up headlights added to its aerodynamic character. The design study was fitted with a 1.2-liter engine and various computer functions.
