As well as the fact that a 214 hp Nissan Leaf does not (or hardly?) requires drive train cooling. I know the batteries do not need cooling, perhaps the motor requires a bit of cooling.
This is just common sense.
I suspect the initial, shocking claims were made in an attempt to stir up controversy -- and it worked!

I'd blame Dr. Wolf for some of the confusion. While he 'mentioned' some of the caveats, and actually provided quanta for the 'improved radiator', he failed to account for the ' blower-assisted ' losses and full chain of custody for entropy.
The other sticking point for me is that, in using the Tesla Model S, we may be talking about the 155-mph versions, while the 110-mph version goes unmentioned. The heat flux variability between the two velocities, cooling system size, and associated drag, is geometrically different, and if left unmentioned, would fall way short of serving the student.
A simple comparison of the cubes of the two velocities will tell the tale.
