The Lexus LS is a full-size luxury sedan that serves as the flagship model of Lexus, the luxury division of Toyota. Four generations of the sedan have been produced, all equipped with V8 engines and rear-wheel drive, although since 2006 all-wheel drive, hybrid, and long-wheelbase variants have also been offered. The original Lexus LS 400, the first Lexus to be developed, was introduced as the premium marque's debut model in September 1989. Subsequent redesigns included the second-generation LS 400 in November 1994, the LS 430 in January 2000, and the LS 460/LS 460 L series in 2006. A domestic-market version of the LS 400 and LS 430, badged as Toyota Celsior, was sold in Japan until the Lexus marque was introduced there in 2006. In 2006 (for the 2007 model year) the fourth-generation LS 460 debuted the first production eight-speed automatic transmission and an automatic parking system. In 2007, V8 hybrid powertrains were introduced on the LS 600h/LS 600h L sedans.
Development of the Lexus LS began in 1983 as the F1 project, the code name for a secret flagship sedan effort. The resulting sedan followed an extended five-year design process at a cost of over US$1 billion, and premiered with a new V8 engine and multiple luxury features. The Lexus LS was intended from its inception for export markets, and the Lexus division was formed to market and service the vehicle internationally. The original LS 400 debuted to strong sales, and was largely responsible for the successful launch of the Lexus marque. Each successive iteration of the vehicle has ranked as the best-selling flagship luxury sedan in the United States.
Since the start of production, each generation of the Lexus LS has been produced in the city of Tahara, Aichi, in Japan. In U.S. consumer publications, Lexus' flagship model is recognized as one of the most reliable vehicles ever built, having held the top ranking in J.D. Power and Associates' U.S. Vehicle Dependability Survey for fifteen consecutive years (1994–2009), and receiving Consumer Reports' highest rankings for vehicle dependability.
