On the lower end, if you look at, say, a Chevy Spark vs a Spark EV -- it's pretty obvious the EV has smaller grill openings.
Or Chevy Volt compared to Chevy Cruze. There are lots of examples of similar models where the EV version requires less airflow.

I don't have any data on other EVs. I do have data on other powerful cars (eg Porsche 911) and it has lower cooling drag than the Taycan - and by a lot.
As for regarding grille size as an indicator of percentage cooling drag - there is a lot wrong with that approach, which I why I like measured data.
But my main point is that the cooling drag of an EV is nowhere near zero (and has often been claimed here) and may in fact be higher than many internal combustion engine cars.
