Lexus introduced the GS 350 in the 2007 model year as a replacement for the GS 300, which had been continuously produced from the 1993 to the 2006 model year. The car got a newly designed, 3.5 liter engine that produced 272 horsepower - a 27 point jump from the 3.0 liter GS 300. Like its predecessor, the GS 350 is a six cylinder engine, but Lexus seems to have eliminated some of the "sluggishness" that plagued the GS 300 for most of its tenure. Namely, the GS 350 had "fast acceleration" and a "smooth, quiet ride." "Before you know it you are driving 85 and you feel like you're driving 60," wrote one owner. Interior and comfort features all got high marks from owners.
