About the 2009 Lexus GS

3rd generation GS (2006-2011; GS 450h joined for 2007), post-2008 update year.

The 2009 Lexus GS is Lexus’ midsize luxury sport sedan for buyers who want strong power and rear-drive balance without giving up the brand’s trademark quiet ride, rich cabin materials, and easy everyday comfort. Lexus positioned the GS range around a mix of luxury and sport performance, with a V6 GS 350, V8 GS 460, and hybrid GS 450h giving shoppers three different ways to get the same polished, refined sedan formula.

The GS 350 is the all-around version, with a 303-horsepower V6, leather-trimmed power seats, and keyless entry with push-button start. The GS 460 is the gas flagship with a 342-horsepower V8, while the tech-focused GS 450h pairs a V6 and electric motor for 340 total horsepower and adds heated and ventilated front seats, a backup camera, and parking sensors.
