The 2018 Lexus GS 350 is a multitalented luxury sedan that artfully blends comfort, sophistication and performance. Despite its advancing age — the current generation has been around for five years — the GS still makes a compelling choice with a well-appointed interior, eager powertrain, sure handling and a smooth ride. All-wheel drive is available for those who often drive in wet weather, and there's even an F Sport model that ratchets up the sporting quotient without sacrificing much comfort. The heart of the GS 350 is a 311-horsepower V6 engine. It lacks the dominating thrust found in rival sedans with turbocharged or supercharged six-cylinder engines but nonetheless impresses with a smooth power delivery. Recent tech and safety upgrades, such as a full suite of driver aids including adaptive cruise control, automatic emergency braking and lane control, make the GS a more compelling choice than ever. There are no significant changes for the 2018 model, although Lexus now includes its roadside and emergency assistance program free for a full 10 years, which should offer additional peace of mind for the long road trips to which the GS is so well-suited. With its incremental upgrades year over year, today's GS is even more luxurious, smooth, comfortable and engaging than it was at the outset.
