Suppose you have the diffuser and the hood?
IC engines producing 10kW of propulsive power would produce 40kW of heat, of which maybe 20kW would be exhaust heat and 20kW would be coolant heat, whereas an electric car producing 10kW of propulsive power would produce 200w of heat in the controller. And maybe 1kW in the motor, so I think there is a large difference.
