The Lexus LC500 Multistage Hybrid
The Lexus LC 500h features a new Multi Stage Hybrid System with much stronger and direct acceleration.
The new Multi Stage Hybrid System was developed with ostensibly opposing goals in mind. It wanted to create a hybrid with a more sporting and engaging driving experience, with a closer alignment between engine speed and throttle inputs, while at the same time achieving the best balance of power and fuel consumption.

It features all the elements of a traditional full hybrid powertrain, including a 3.5-litre V6 petrol engine, a powerful electric motor and a lithium-ion battery, together with a four-speed automatic gearbox mounted at the rear of the hybrid transmission.
The electric motor generates better acceleration feel than a conventional engine, and the introduction of physical gears allows for engine revs to be more closely matched to the driver’s use of the accelerator. The result is a much more direct connection between accelerator pedal inputs and vehicle acceleration, with nought to 62mph brought well into the sub-five-second range.
The Multi Stage Hybrid Drive System is the first Lexus full hybrid system to provide an ‘M’ transmission mode, allowing the driver to make direct and responsive gear changes and enjoy the most sporting and engaging drive yet from a Lexus hybrid.
A new, lightweight and compact electric motor and lithium-ion battery offset the weight of the added automatic transmission, so the new system weighs the same as the current Lexus full hybrid system.
