Comparing ICE and EV variants doesn't help, because it is more than just the cooling that has changed, the gearbox is different, they may use narrower tyres, different rims, there is no fuel tank or exhaust, the battery pack may form an undertray where previously there wasn't one etc.
There is no need to "fix" anything, aerodynamic drag is proportional to speed squared, that is why we have Cd

1) an example: are shutter positions, if present, accounted for?
2) is air conditioning 'conventional' or 'heat pump?'
3) is radiator and condenser series, or parallel?

The act of presenting ICE and BEV variants allows an observer to 'focus' in on the existing variations which lead to the differences, in order to parse out the specifics. I see no harm, only the contrary.
