Energy-efficient driving, using the gas/petrol engine as the main power source
Toyota's hybrid vehicles use the gas/petrol engine in the speed range in which it operates with good energy efficiency.
The power produced by the gas/petrol engine is used to drive the wheels directly, and depending on the driving conditions, part of the power is distributed to the generator. Power produced by the generator is used to feed the electric motors, to supplement the gas/petrol engine.
By making use of the engine/motor dual powertrain, the energy produced by the gas/petrol engine is transferred to the road surface with minimal loss.
*If the battery charge level is low, the power output from the gas/petrol engine is increased to increase the amount of electricity generated to recharge the battery.
