A hybrid version of the Lexus LS, the LS 600h L, was previewed at the New York International Auto Show in April 2006. The first 100 LS 600h L sedans sold in the U.S. were offered as "Launch Edition" models via the Neiman Marcus catalog. Lexus LS600hl models do not have keyless entry remote fob smart keys that are onboard programmable and therefore require special equipment in order to program the keyless entry remote fob smart key.
