How and when does Lexus Hybrid Drive switch from petrol engine to electric motor or motors?
Due to the seamlessly smooth operation of Lexus Hybrid Drive, you will usually not notice the switch between electric and petrol power. However, on the power flow monitor on your dashboard you’ll see that at start-up and at lower speeds usually only the electric motor(s) powers the vehicle. As speed increases, the Power Control Unit (PCU) will call on the petrol engine to provide additional power. At cruising speeds, the electric motor or motors will often be working as generators. And the PCU will call on additional electric power when you wish to accelerate hard.
