The LS 500h (the “h” referring to hybrid) uses a Multistage Hybrid System that combines a naturally aspirated Atkinson-cycle 3.5-liter V6 gasoline engine with two electric motor/generators powered by a compact, lightweight lithium-ion battery. For 2021, an even more dramatic powertrain improvement has been made to the Multistage Hybrid System, as the system is now tuned to utilize a new battery strategy and drive more power through the electric motors upon acceleration. The Multistage shift software has also been updated to take advantage of this electric power appearing earlier in the powerband. Combined system output of the internal combustion engine with the electric traction system is 354 hp, enabling the LS 500h to accelerate from 0-60 mph in 5.1 seconds (RWD).
