I have no idea about the car - I am quoting only what you wrote. And you wrote, "The exhaust tunnel is closed". That will immediately reduce drag, and so the value of overall aero drag we're comparing to has also changed.

You are right, newton depend upon speed, then use delta Cd. For example the Up and e-Up have 0.012 delta cd between the two cooling system.
I am not sure if you're trying to be misleading but that statement is quite incorrect. The delta Cd between the two cars is that, not their cooling systems. We have no data at all on their cooling systems!

If I compare % upon the two I could may be find that the electric model have more (I am sure not). In my opinion, what is important is that the drag is more important for the thermal model, the Up.
I don't know what that means.
