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. The Optima name is now going to be used for all markets except China, where they will use the South Korean market name.
From 2000-2005 Optimas were a rebadged variant of the Hyundai Sonata, differing only from the Sonata in minor exterior styling details and equipment content.
In a March 2012 comparison test by Car and Driver, the Optima came in third place out of six cars behind the first place Volkswagen Passat and the second place Honda Accord.
The 2011 Kia Optima Hybrid was unveiled at the 2010 Los Angeles Auto Show, and was launched in the U.S. market in November 2011. During its first month in the market sold 524 units. Considering cumulative sales in the U.S. market through December 2011, with 19,672 units sold, together the Hyundai Sonata Hybrid and the Kia Optima Hybrid ranked second in hybrid sales for calendar year 2011, after the Toyota Prius.
The third generation Kia Optima is an official entry in the Pirelli World Challenge.
