The only externally apparent features that differentiate it from the Kia Optima are the hybrid badging, application specific wheel design, a lowered ride height by approximately , and the availability of a special light platinum graphite paint color. It also utilizes an active shutter system behind the upper grille, allowing the car to redirect airflow when the gas engine's heat levels allow (such as when the car is operating in EV mode to improve aerodynamics, or to assist in more rapid warming up of the gas engine).
