Hi, Vekke
I found a paper about a car for which the front radiators air drag is considered equal to zero.
Probably Julian is talking of this car.
But this car don't answer to Julian sentence:

Some ICE cars have zero cooling drag.

Because on this paper only the radiator cooling drag is said being zero drag.
They don't speak about the exhaust drag, muffler, catalyst cooling drag. This devices need cooling.
And this zero drag is not because there is an ICE engine, it is because a clever engineer found this idea. The same would be possible for Bev car, Phev car ...
This idea is to send outlet air coming from radiators in front of the front wheels.
