Lexus is the luxury vehicle division of Japanese automaker Toyota Motor Corporation. First introduced in 1989 in the USA, 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, and has ranked among the ten largest Japanese global brands in market value. Lexus is headquartered in Nagoya, Japan. Operational centers are located in Brussels, Belgium and Torrance, California, USA. 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. Until 2005 Lexus did not exist as a brand in its home market and all vehicles marketed internationally as Lexus from 1989-2005 were released in Japan under the Toyota marque and an equivalent model name. 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.
