In April 2011, Lexus showed the concept-car LF-Gh at the New York Auto Show.
It was the fourth generation of its mid-range saloon, the GS. The series version was shown had its world premiere at the Pebble Beach Concours d’Elegance in California in August 2011.

Its look is very complicated, with a lot of lines and edges on the front bumper. It looks like it was 3D-printed, not molded. By the fourth generation, Lexus already established itself as a top-quality name in the U.S., and the biggest question was about the drivetrain.

At its debut, the fourth generation model was shown in rear-wheel drive GS 350, powered by a V6 engine mated to a six-speed automatic transmission. Various engine variants followed, including all-wheel-drive systems, all-wheel-steering systems and two hybrid versions. Since it is a luxury vehicle, no manual transmission was offered.

Inside, there is a new infotainment system, with Siri Eyes Free mode from Apple and other hi-tech features were installed in the GS. The sound system is signed by Mark Levinson and promised to transform the cockpit into a concert hall.

The seats are 10-way power assisted as standard and 18-way as an option. Other optional features further include a pre-collision system, Heads-Up Display, blind spot monitor, lane keep assist, and Driver Monitoring System.
