F Sport specification on the LS 500h is the version worth seeking out, bringing a more focused character to Lexus's flagship without compromising the refinement that defines it. Power comes from a 3.5-litre V6 hybrid system producing 354 horsepower, and with a Rear-Wheel Drive layout and an electronic limited-slip differential at the rear, it drives with considerably more purpose than the standard car. The F Sport interior is a genuine upgrade, with deeply bolstered leather seats offering heating and cooling up front and heating in the rear, all wrapped in a cabin that includes the 23-speaker Mark Levinson surround sound system and a 12.3-inch infotainment display with Apple CarPlay and Android Auto. A heads-up display, digital rear-view mirror, wireless charging pad, and dual-zone climate control are all present, and the soft-close doors and advanced self-parking system speak to how thoroughly this car is equipped. Triple-beam LED headlights, a blind spot monitor, adaptive cruise control, and the full Lexus Safety System+ suite round out a specification that leaves very little to add. As a JDM example, it arrives with the quality of finish and attention to detail that the Japanese domestic market demands, making this a rare opportunity to own Lexus's best in its most driver-oriented form.
