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.
