See Autopedia's comprehensive Lexus GS Review. Though essentially identical, GS and the Aristo differed in their engine and transmission combinations as well as equipment packages. A hybrid version, the GS 450h, arrived for the 2007 model year. The third generation GS, designed using an all-new platform, premiered globally for 2006. For most of its life, the GS had a longer wheelbase than the ES, and was shorter than the ES in length. The model was designed to fill the gap between the Lexus ES and Lexus LS and to provide Lexus with a sports sedan that could compete with the BMW 5 Series and the Mercedes-Benz E-Class.

The first GS, based on the platform and running gear of the Toyota Crown, was introduced in 1991 in Japan and two years later in the United States, Europe and selected markets in Asia. The first two generations were sold as the Toyota Aristo in Japan, until the introduction of Lexus in that country in 2005. The Lexus GS is a rear-wheel drive, luxury sports sedan manufactured by Toyota for its Lexus division.
