Question: how much power in watts is required by the motor to run a car of 100 kg?
Answer: The total load, comprising of the weight of the driver and other luggage, but excluding the weight of the vehicle, is around 100 kg. I have been measuring the power at the wheels. Most of the time, the power consumption is around 5 hp, when driven at 15 km/h. 1 hp= 736 watts.
