What is the BMW ActiveHybrid 7?

[LiamLynn]

BMW ActiveHybrid 7 is a new energy vehicle in the BMW 7 Series, where ActiveHybrid refers to hybrid power. The following is a related introduction to hybrid power: 1. Overview: Hybrid power means the car uses both gasoline and electric power as driving methods. The advantage is that when the vehicle starts and stops, it is only driven by the motor. The engine does not work until a certain speed is reached, thus keeping the engine always in the best working condition, with good power performance and very low emissions. Moreover, the source of electric energy is the engine, and only refueling is needed. 2. Development: The key to hybrid vehicles is the hybrid power system, whose performance is directly related to the overall performance of the hybrid vehicle. After more than ten years of development, the hybrid power system assembly has evolved from the original discrete structure of the engine and motor to an integrated structure of the engine, motor, and transmission, known as the integrated hybrid power system.
