Some 'BEV' considerations of the Porsche:
1) it's a 'small' car
2) it's a 4-passenger car
3) it's greenhouse is small in comparison to Taycan/ Model S
4) it's low power compared to Taycan / Model S
5) it has a 553.9-kWh-e 'pack'
6) it consumes an approximate average 1,890 Wh /mile
7) it has an average range of about 51.2-miles with the Taycan's 93.4 kWh battery
8) approximately 33.333% of it's heat flux disappears by magic
9) one condition of it's ,low-drag cooling system is it's 'improved' radiator ( as an example to the significance of this, switching from aluminum, to copper, would effect a 67.8% improvement in heat transfer, with associated downsizing, 80.2% for silver ).
10) switching from propylene glycol, to ethylene glycol would alter the coolant boiling point from, 369-F, to 387-F.
11) allowing a 'higher operating coolant temperature' would allow for a downsized cooling system, and drag.
12) increasing allowable cooling system pressure ( flash point ) allows for a smaller cooling system ( lower drag ).
13) without ' blower-assisted' cooling, on 'track days', the Porsche could experience walk-home engine failure.
