*From what I can glean online, both these BEVs use passive and active battery cooling, although nothing about motor cooling is mentioned.
* The 'active' cooling involves the vehicle's air conditioning system, which is used during recharging and discharge, to help keep the pack within design limits.
* Since there is no dedicated 'radiator', and no engine bay, it seems plausible that designers would have freedom to engineer air-tight ducting with optimized inlets and outlets, for these single heat exchanger systems.
* That said, then both cars would be candidates for exceptionally low-drag cooling systems.
* And since neither car is necessarily a paragon of low drag, their cooling system drag, as a percentage of overall drag, might demonstrate a low percentage.
