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 luxury cars. As of 2009, Lexus vehicles are officially marketed in over 70 countries and territories worldwide. The Lexus marque has ranked among the top ten Japanese global brands in market value. The division's world headquarters are located in Toyota, Aichi, Japan, with operational centers in Brussels, Belgium, and Torrance, California, United States. Lexus originated from a clandestine flagship sedan project that began in 1983. This effort developed into the original Lexus LS, which was the first vehicle to wear the Lexus marque upon its launch in 1989. In following years, Lexus added sedan, coupe, convertible, and SUV models. In 2005, a hybrid version of the RX crossover debuted, and additional hybrid models were subsequently introduced to the Lexus lineup. In 2007, Lexus launched its F marque performance division with the arrival of the IS F sport sedan.
