What is a Hybrid System?
A hybrid system combines different power sources to maximise each one's strengths, while compensating for the others' shortcomings. A petrol-electric hybrid system, for example, combines an internal combustion engine's high-speed power with the clean efficiency and low-speed torque of an electric motor that never needs to be plugged in.
Are All Hybrids Created Equally?
There are several ways in which electric motors and a petrol engine can be combined.
Toyota perfected the series/parallel or "full" hybrid to deliver the energy-saving benefit of a series hybrid together with the acceleration benefit of a parallel hybrid. Two key technologies — the power split device and sophisticated energy management — make this possible. They constantly optimise the flows of mechanical power and electric power for safe and comfortable vehicle operation at the highest possible efficiency.
