The Lexus GS is a series of mid-size luxury sports sedans / executive cars sold by Lexus, the luxury division of Toyota. The first GS, based on the platform and running gear of the Toyota Crown, was introduced in 1993 in the United States, Europe and selected markets in Asia. The second generation model premiered in 1998, using a new platform and adding a V8 version for the first time outside Japan. The current third generation GS, which premiered globally for the 2006 model year, comes in both V6, V8, and hybrid versions (GS 450h performance hybrid).
The GS was designed to fill the gap between the ES and LS and to provide Lexus with a sports sedan which could compete with the BMW 5-Series and the Mercedes-Benz E-Class. In Japan, the GS was sold as the equivalent Toyota Aristo, which debuted in 1991 and was sold until the introduction of the Lexus marque there in 2005. Following the debut of the third generation GS, the Toyota Aristo was discontinued. Though essentially identical, GS and the Aristo differed in their engine and transmission combinations as well as equipment packages.
