Since the internal combustion engine was invented there has been continuous development to get as much useful fuel/air mixture into the cylinders in order to produce as much power as possible in an efficient way from the smallest, lightest engine.

In the electric vehicle massive power is available easily by connecting the battery to the motor. Unfortunately this arrangement would make everything catch fire, so the control unit is there to limit the power and ration it in a way that the heat is dealt with and the battery lasts a reasonable time.

When I was an apprentice 50 years ago we messed around with an electric "invalid carriage" (as they were known then) and sure enough it was easy to turn it into a dragster with amazing power, for a very short time!
