Lexus originated from a corporate project to develop a new premium sedan, code-named F1, which began in 1983 and culminated in the launch of the Lexus LS in 1989. Subsequently, the division added sedan, coupé, convertible and SUV models. Lexus did not exist as a brand in its home market until 2005, and all vehicles marketed internationally as Lexus from 1989 to 2005 were released in Japan under the Toyota marque and an equivalent model name. In 2005, a hybrid version of the RX crossover debuted
corporate reorganization from 2001 to 2005, Lexus began operation of its own design, engineering and manufacturing centers.
Since the 2000s, Lexus has increased sales outside its largest market, the United States. The division inaugurated dealerships in the Japanese domestic market in 2005, becoming the first Japanese premium car marque to launch in its country of origin. The brand was introduced in Southeast Asia, Latin America, Europe and other regions.
