The 2018 Lexus GS 350 represents the fourth generation of Lexus's midsize luxury sedan. Under the hood, the GS 350 features a potent 3.5-liter V6 engine that delivers 311 horsepower, mated to an 8-speed automatic transmission for RWD models and a 6-speed automatic for AWD models. Available in two trims: the base GS 350 and the GS 350 F Sport, it offers plenty of luxury and sportiness. Key safety features include the Lexus Safety System+, which includes adaptive cruise control, lane departure warning with steering assist, automatic high beams and forward collision warning with pedestrian detection. Infotainment comes delivered via a 12.3-inch screen, complete with navigation, and it is also compatible with Siri Eyes Free, a unique feature for iPhone users. Notable changes for the 2018 model year include standard inclusion of the previously optional premium package, which adds rain-sensing wipers, a power rear sunshade, and ventilated front seats.
