Yes, but that's kind of cheating as it uses its cooling system exaust as air curtains for the front wheels.

Partialy correct, cooling system design indeed makes a major difference in drag.
However for a given type of design, drag increases with airflow demand.
And you can only realisticly feed two air curtains, there is only so much air they need.
If it was a little smaller, it might even have net negative drag.

The Model S also has issues because of its undersized cooling system while the Taycan does not.
And the Taycan carries a drag penalty for it, making it a known "electron guzzler", but it can make up for it in higher cruising and charge speed.
