The Lexus GS, the equivalent of the third-generation Aristo, made its debut in August 2005 simultaneously with the inauguration of the Lexus channel in Japan. (The Aristo line had been due for remodeling at the time, but was discontinued without entering the third generation.)

The Lexus GS initially came in two versions in Japan with different engine displacements. The GS 430 model was equipped with a 4.3-liter V8 engine (3UZ-FE) producing 280 PS, and the GS 350 came with a 3.5-liter V6 engine (2GR-FSE) developing 315 PS.

In March the next year, the GS 450h was added to the lineup as the first hybrid model of Lexus in Japan. Although its engine was the same 3.5-liter unit that powered the GS 350, the motor-assisted hybrid system could produce 345 PS, which was comparable to the output of a 4.5-liter engine -- hence the figure 450 in the model name. In a minor model change in October 2007, the V8 engine was upgraded to a newly developed 4.6-liter engine (1UR-FSE) with 347 PS, and the model fitted with this engine was renamed the GS 460. At the same time, the 6-speed automatic transmission was replaced with an 8-speed automatic.
