Lexus is the luxury vehicle division of Japanese automaker Toyota Motor Corporation. First introduced in 1989 in the United States, Lexus is now sold globally and has become Japan's largest-selling make of premium cars. The Lexus marque is marketed in over 70 countries and territories worldwide. Lexus is headquartered in Nagoya, Japan. Operational centers are located in Brussels, Belgium, and Torrance, California, United States. Lexus originated from a clandestine flagship sedan project, code-named F1, which began in 1983 and culminated in the launch of the original Lexus LS in 1989. Subsequently, the division added sedan, coupé, convertible, and SUV models. In 2005, a hybrid version of the RX crossover debuted, and additional hybrid models later joined the division's lineup. In 2007, Lexus launched its own F marque performance division with the debut of the IS F sport sedan, followed by the LFA supercar in 2009.
