Slotting between the flagship LS 460 and the popular ES 350, the mid-size Lexus GS line occupies an admittedly modest but still notable niche in the sport sedan segment. Intertwining aggressive styling and formidable performance with typical Lexus luxury cues, it gives Toyota's premium division a very credible competitor in an arena most often associated with German offerings, including the Audi A6, BMW 5 Series and Mercedes E-Class. In addition to offering the only hybrid in this segment, the GS 450h (reviewed separately), the GS lineup consists of three gasoline-powered variants. The rear-drive GS 350 and all-wheel-drive GS 350 AWD share a common 3.5-liter V6, while the rear-drive GS 460 is powered by a larger and more powerful V8 engine.
