I thought I'd throw out another question for you technically knowledgable persons.
I seem to have caught somewhere that an electric engine doesn't get much less efficient at smaller loads as the power increases? In other words if I have a 30kW electric engine and a 225kw engine and my 2500lbs car is moving on a flat normal road at 40mph, assuming everything else is equal how much power would each engine draw?
The reason I ask is that my impression is that using ICE engines without any special fuelsaving measures like cylinder deactivation the difference would be huge. Lets say between a 75kW I4 and a 150kW I4 using the same speed and road above the bigger one would be using around 80% more fuel than the smaller one?
Anyone that know this?
