The development of the Lexus LS began in 1983 as the internal / Toyota secret project "F1". This project included a five-year plan, the development funds of over one billion U.S. dollars were available. The result was a newly developed V8 engine ( 1uz platform ) based on IndyCar / Champ Car engines. There were also multiple luxury features. The result of the F1 project was provided from the outset as a product for export markets, which is why Lexus was founded as a separate brand. The LS 400 debuted with success and was largely responsible for the successful establishment of the Lexus brand. According to a survey conducted annually buyers in the U.S. through the company's JD Power and Associates ' U.S. is the LS series in the years 1994-2009 the most reliable in its class.
Since the start of production, each LS- generation is produced in the city of Tahara ( Aichi ) in Japan.
