And there you have it zero drag penalty in ev from cooling system. They use panel coolers and beause their car is so aerodynamic it can go away with zero drag penalty at least that is what they claim.
No paper to prove that claim at the moment, but eye can tell that migth be true as there is no cooling inlets to be seen.
That same system would not be possible in ICE vehicle as it creates so much more extra heat.
Edit:
Ofcourse the cooling drag is newer zero as water inside the cooling system or the air circulating inside cabin creates also drag to some degree. So there is cooling drag, but minimal to none aerodynamic drag extra from cooling.
