Lexus offers two powertains for the LS; a twin-turbo V6 producing 415 horsepower and a hybrid system featuring a 3.5L V6 that makes 354 horsepower. But Lexus is considering adding more powertains to their flagship sedan.
Toshio Asahi, chief engineer for the LS told Australian outlet GoAuto that all powertrain options including a plug-in hybrid, hydrogen, and electric were “all on the table” for the current model. The most likely reason for this is competitors such as BMW and Mercedes-Benz have plug-in hybrid models of their flagship sedans and are working on new electric models. There is also the elephant in the room known as the Tesla Model S.
Hydrogen isn't that much a surprise. Parent company Toyota has been pushing hydrogen for a number of years. But the lack of an extensive hydrogen infrastructure has limited its appeal and caused Toyota to put more focus on electrics. It should be noted that the LF-FC concept shown in 2015 was a hydrogen fuel cell vehicle. On the electric front, Toyota has been working on solid-state batteries that promise more range and quicker charging. Plans are to have batteries go into production beginning in 2022.
Asahi also mentioned that engineers are looking into improving the current hybrid powertrain - possibly adding more power.
