  • Electric motor: approx. 90%
  • Electric motors have a much smaller size and volume than internal combustion engines, so their performance is always much higher.


Cars with electric motors will have a much faster speed than cars using internal combustion engines.

The reason is that the car uses an electric motor when working steadily and can generate torque. And vehicles using internal combustion engines achieve high working speed to achieve torque.

Engine characteristics

Electric motor has a lot more advantages than internal combustion engine because it has created its own advantage when its characteristic line is close to the actual human desire.

Meanwhile internal combustion engine needs the assistance of the powertrain.

Maintenance costs, use

Because cars that use electric motors will use batteries to operate, the cost will be many times lower than that of cars using internal combustion engines.
