The world’s only range of premium hybrid cars intelligently combines petrol and electric power ...
... to deliver outstanding performance with reduced emissions and improved fuel economy.
At the heart of the GS 450h is an ultra smooth and powerful V6 engine
The power control unit, the brain of Lexus Hybrid Drive, manages the most efficient combination of petrol and electric power.
The hybrid transmission ensures the ultra-smooth transition between power sources and delivers stepless acceleration.
It contains a generator, planetary gears and electric motor, with the generator converting surplus engine power into electricity...
...to re-charge the hybrid battery.
Inside the car, the energy monitor shows what the Lexus Hybrid Drive system is doing at all times.
Typically, when the GS 450h starts up - and when driving at low speed - it is powered solely by the high performance electric motor.
In this mode, the car is almost silent, uses no petrol and there are no emissions.
As speed increases, the petrol engine starts automatically and the hybrid system smoothly transfers to V6 petrol engine power.
One of the most remarkable features of the system is regenerative braking. When the brakes are applied; the electric motor acts as a generator,
capturing kinetic energy otherwise lost as heat, and transferring it to the battery which never needs an external recharge.
The breathtaking performance of the GS 450h when it accelerates from cruising speed
is due to the electric motor supplementing the petrol engine to give a dramatic surge of acceleration just when you need it.
Lexus Hybrid Drive - innovative thinking ahead of its time.
