The electric vehicle has a propeller as well as the electric motor. This begins to turn according to the slip stream caused by the forward movement of the vehicle, guided through channels. The propeller has hollow blades increasing in size as the radius increases and which are filled with oil. The oil is supplied from a reservoir when the vehicle moves forward and the oil returns to the reservoir when the vehicle stops. The propeller is in the lower region of the vehicle, over the roof or inside the vehicle.
