The Kia Optima is a mid-size four-door sedan manufactured by Kia Motors since 2000 and marketed globally through various nameplates. First generation cars were mostly marketed as the Optima, although the Kia Magentis name was used in Europe and Canada when sales began there in 2002. For the second generation models, Kia used the Kia Lotze & Kia K5 name for the South Korean market, and the Magentis name globally, except in the United States and Malaysia where the Optima name was retained.
