The Lexus LX (Japanese: レクサス・LX, Hepburn: Rekusasu LX) is a full-size luxury SUV sold by Lexus, a luxury division of Toyota since January 1996, having entered manufacturing in November 1995. It is Lexus’ largest and most expensive luxury SUV. Four generations have been produced, all based heavily on the long-running Toyota Land Cruiser SUVs. The first-generation LX 450 started production in 1995 as Lexus’ first entry into the SUV market. Its successor, the LX 470, premiered in 1998 and was manufactured until 2007. The third-generation LX debuted at the New York International Auto Show in April 2007. The fourth-generation LX debuted in October 2021.
The first-generation LX 450 had a straight-six engine and seats for seven passengers. The second and third-generations had a V8 engine powertrain, a welded steel body-shell combined with full-size steel ladder frame (body-on-frame construction), and seats for eight passengers. The fourth-generation model has a twin-turbocharged V6 engine powertrain and seats for seven passengers as standard and four passengers as an option. The second-generation LX 470 shared exterior styling with the Japanese domestic market Land Cruiser Cygnus.
According to Lexus, the “LX” name stands for “Luxury Crossover”. However, some Lexus importers use the backronymic name, “Luxury Four Wheel Drive”.
