The LS is the car that created Lexus. Developed under Toyota's secret 'F1' programme — a $1 billion, 1,400-engineer project initiated by Chairman Eiji Toyoda in 1983 — the LS 400 debuted at the January 1989 Detroit Auto Show and went on sale in the US that September with a 4.0-litre V8 that was quieter, faster, and more refined than any German rival at its price point. Road & Track and Car and Driver put the LS 400 on their Ten Best lists, and by 1991 Lexus had displaced Mercedes-Benz as America's top-selling luxury import.
Four more generations followed across three decades. The second-generation LS 400 (1995–2000) grew the wheelbase and shed weight; the third-generation LS 430 (2001–2006) added adaptive cruise control and a Mark Levinson audio system. The fourth-generation LS 460 (2007–2017) arrived with a then-novel eight-speed automatic and a parallel-park-assist system. The current fifth-generation LS 500 (2018–present) uses a twin-turbocharged V6 and is offered as the LS 500h hybrid, abandoning the V8 but gaining far sharper dynamics.
The LS has served as Lexus's halo and its proof-of-concept for every generation, even as the RX crossover surpassed it in volume. Its reputation for long-term reliability and near-silent refinement remains the foundation of the Lexus brand identity.
