The LS is Lexus's full-size flagship sedan and the original model that established the brand in 1989 — within the site's post-1995 scope spanning the 2nd gen final years (1995-1997 LS 400) through the 5th gen current model. The launch LS 400 in 1989 was the car that made Lexus credible against Mercedes S-Class and BMW 7 Series, with bulletproof 1UZ-FE V8 reliability that set new standards for luxury-car build quality. Across the post-1995 years: 2nd gen (1995-1997, UCF20) final years with 4.0L 1UZ-FE V8 (260 hp); 3rd gen (1998-2006, UCF30) as LS 430 with 4.3L 3UZ-FE V8 (290 hp); 4th gen (2007-2017, USF40) as LS 460/600h with 4.6L 1UR-FSE V8 (380 hp) and 5.0L hybrid V8 (438 hp combined) — first 8-speed automatic in the segment globally, optional all-wheel drive added; 5th gen (2018-present, F50) as LS 500/500h with 3.5L 2GR-FKS twin-turbo V6 (416 hp) and 3.5L hybrid V6 (354 hp combined) on Lexus GA-L platform shared with LC, ten-speed automatic. Always built at Tahara plant, Japan. Sales peaked above 50,000 annually in the early 2000s before declining steadily as the broader luxury market shifted to SUVs — the LS was on the bestseller list in the US until 2008 but the global financial crisis cut sales by 42%. Now firmly the cult collector Lexus — 1990s LS 400/430 examples are appreciating, with very-low-mile original-condition cars commanding strong premiums.
