2011 Lexus LS460 IV 4.6 AT AWD Executive

In 2006, Lexus launched the fourth generation Lexus LS, offering the first long wheelbase version of its flagship model. Beginning with the 2008 model year, an all-wheel drive hybrid joined the line up. The new LS also introduces the latest in Lexus technology, including the first production eight-speed automatic transmission, an automatic parking system, and on the hybrid models, the first production LED headlamps in the U.S. market. Several different Lexus LS models are sold worldwide, including standard, long wheelbase, hybrid, and all-wheel-drive versions.

Lexus' flagship model has held the highest ranking in J.D. Power’s Vehicle Dependability Survey for over twelve consecutive years, and Consumer Reports has named the LS as the most dependable vehicle ever tested. In 2007, international jurors named the LS 460 as the World Car of the Year.

In August 1983, Toyota chairman Eiji Toyoda initiated the F1 project ("Flagship" and "No. 1 vehicle"; alternatively called the "Circle-F" project), a top secret effort aimed at producing a world-class luxury sedan. Unlike past Toyota efforts, the F1 project was not bound by a specific budget or time constraints. It also did not utilize existing Toyota vehicle platforms or parts. Instead, chief engineer Ichiro Suzuki sought to develop an all-new design that would surpass existing flagship luxury sedans. Specific targets included: a more aerodynamic exterior, quieter cabin, higher top speed, and more fuel-efficient design versus American and European rivals.
