The three major components of a traditional fuel vehicle are the engine, gearbox and chassis, while the three major components of a new energy vehicle are: motor, power battery, and electronic control system. There is a reason why new energy vehicles are not equipped with gearboxes because they do not need them.

Traditional fuel vehicles rely on the engine to provide power, but the engine's power output range is relatively narrow. When it is at a low speed, there is no effective torque. If it reaches a high speed range, its torque will drop very quickly, and the speed is set The torque output of the engine can be adjusted behind the box, and a relatively large torque can be obtained in the low-speed gear. With the gearbox, it can take into account both low and high speeds, and at the same time have a relatively large torque output on the wheels.

The electric motor of an electric car is different from an internal combustion engine. It can obtain a speed of 7000-10000 rpm as long as it starts to run. The power output is faster and more fierce than an internal combustion engine. It can still operate normally without a gearbox. Therefore, electric vehicles do not need a gearbox.

Electric cars don't need a gearbox. If you have to add one to it, it is superfluous. Of course, in the earliest time, Tesla tried to use a gearbox, but the effect was not good, and it added tens of kilograms for no reason, so it was also cancelled. Now electric vehicles do not need a gearbox.
