For many, this sedan is the sportiest of the Lexus family, and the most elegant. This year, this title might have to go to the IS-F since its V8 engine surpasses it. Buyers have a lot of choice when it comes engines, from the GS 430's V8 to the GS 450h's hybrid power train. And if one opts for the most fuel-efficient non hybrid version, the GS 350, there is no need to worry as its V6 engine is quite appropriate. And like all other Lexus models, the equipment packages are more than complete.
