The Lexus LS (Japanese: レクサス・LS, Rekusasu LS) is a full-size luxury car serving as the flagship model of Lexus, the luxury division of Toyota. Now in its fourth generation, all LS models have featured V8 engines and rear-wheel drive, with Lexus also offering all-wheel drive, hybrid, and long-wheelbase variants.
As the first model developed by Lexus, the LS 400 debuted in September 1989 with the second generation debuting in November 1994. The LS 430 debuted 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 (Japanese: トヨタ・セルシオ, Toyota Serushio), 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.
