And zero flow-through? I'm of the understanding that even EVs need some level of cooling?

Yes, an important distinction when comparing architecture.
With mirrors, the Cd could degrade easily to 0.20- 0.205. Something we need to account for with any 'camera' car.

Yes, at least for air conditioning.
Some of the low range, and 'slow' BEVs have no facility for liquid cooling of the motor and pack, which would otherwise require a 'radiator' during driving.
During charging, most, if not all, use the AC system to cool the pack, and it becomes a component of the charging loss.
