Dmi super hybrid technology: obviously, at high speed, the engine can burn more fully and the thermal efficiency is extremely high. At this time, fuel economy is much higher than power consumption, and pure electricity can't solve the problem of high-speed energy consumption economy in ten years. With the appearance of BYD DMi super hybrid, the car is driven by a motor at low speed and a special engine at high speed, so that the car always stays in the highest economic efficiency operating range, directly taking into account the strongest power and the lowest fuel consumption. On the other hand, the seamless cooperation of the two power systems directly made BYD cancel the gearbox that was heavily blocked by the patents of western monopoly giants. This part is very expensive. It is precisely because of the cancellation of the gearbox that the cost of DMi plummeted and the price of hybrid cars plummeted. China people can no longer pay taxes on science and technology to the west. It can be said that DMi technology has laid the embryonic form of the highest dynamic value technology in the next decade.
