WARNING: This page is about a different car, the 2008 Lexus GS 450h. However, it is still accessible from the selected car via links, so may be relevant.
The hybrid system is a power train designed to combine and use two different kinds of power sources such as a gasoline engine and electric motor. The system uses the optimum power source, either the gasoline engine or electric motor to fit the driving conditions best and maximizes each one's strengths while compensating for their shortcomings. Thus, a driving performance with a seamless response has been delivered and the fuel consumption and gas emissions have been reduced significantly at the same time.
