It is a very efficient design indeed, but the cooling system on its own isn't that low drag, it manipulates airfoil around the front wheels to reduce drag somewhere else.
It's a genius design, but sadly it doesn't scale up very well as manipulating airflow around the front wheels can't reduce the drag much further.

While this is partialy true, tricks like the 996 don't scale up very well for high cooling air demand vehicles such as the Taycan wich needs a lot more air due to a far lower deltaT.
An example for an ICE with high airflow demands over its radiators would be the Veyron.
I can't find any data on its exact cooling drag percentage, but the 10 radiators are often cited as the culprit for the 0.36-0.41 cd.
