I read it in it's entirety.
It confirms everything I've mentioned.
Very contextual:
1) ' improved radiator' ( non-aerodynamic variable )
2) ' throttling ' ( a Cd 'spectrum' )
3) ' elastic coolant-temperature target' ( non-aerodynamic variable )
4) ' blower-assisted operation ' ( no accounting for engine-to-alternator-to-battery-to-blower fan power consumption )
5) ' cooling-air drag drops proportionately to the cooling-air volume flow rate'
( extremely germane to the BEVs which have been selected for comparison to ICE vehicles ) [ there are twelve different Tesla Model S variations. All twelve need to be included in the comparison ]
Depending on driving velocity, no doubt, some BEVs will demonstrate lower cooling drag than 1.4% of overall drag.
