The Lexus GS model comes in three variations, the GS 350, GS 460, and the hybrid GS 450h. The latter uses a similar engine to the GS 350, but gets extra power from the hybrid system and better average fuel economy.
The GS 450h's gasoline engine is a 3.5-liter V-6, complemented by a robust hybrid system that can drive the car under electric power. Total drive train horsepower is 340, getting the car to 60 mph in 5.2 seconds.
The transmission is continuously variable, using a planetary gear set and motor to seek the best ratio for current driving conditions. It includes sport and manual drive modes, but in manual, the gears are just programmed shift points.
