low-cooling drag Porsche 911 Carrera

[aerohead]

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.

You seemed to have missed the critical point. The Porsche is an example of an ICE engine car that has extremely low cooling drag.

That it is a high-power, high top speed car makes it even more interesting.

You seemed to have completely missed the critical point. The low cooling drag is achieved only by the likes of the caveats I just mentioned. The low drag would be impossible without them. So said Dr. Thomas Wolf.
Also, compared to Taycan, and Model S, the Carrera is:
* small
* light
* low-powered
* small frontal area
If you remove the special conditions of the Carrera's cooling system, your whole argument falls apart. It becomes nothing as special. Pity that your remarks imply lack of reading comprehension.

Such a shame when a theory - ie ICE cars all have lots of cooling drag - is replaced with facts, isn't it?

Fact: ICE cars don't all have lots of cooling drag. In fact, a select few have basically none.

Assuming the "B" means battery, and the "EV" means electric vehicle are you talking about the Taycan or the ICE 911 Carrera?

Both?

The greater shame is, what appears to be more brain vomit, ejaculated into what would otherwise be a scientific discussion pertaining to heat rejection.
What's hoped to be passed off as 'fact', is nothing more than a highly contextual, tip-of-the-iceberg, compartmentalized, data point, which disregards the totality of the topic.
We can cite hundreds of ICE 'cars' with zero cooling drag. That's not the issue.

The permalink is about the 911 Carrera in the context of its performance, if it were a BEV.
It's an attempt to draw attention to the second law of thermodynamics-implications of ICE vs BEV, BSFC-e,.......

I can see that your confusion extends to topics other than car aerodynamics...

As always, the antidote for what appears to you as confusion on the part of others will vanish after you've completed the degree in mechanical engineering.
Reality is what exists outside the mind of the uninformed.
