I think it was alread discussed in this forum:
how much are the closed air vents beneath the A pillar degrading the good aerodynamics of the Taycan?
We will never get quite (precise) answers unless we measure and test ourselves
He are some results of tests done with a 2020 Taycan 4S on custom, quite open, 21" wheels, manual charging doors and small battery done on the autobahn.
The tests were done at night, warm conditions, dry and constant cruise controlled.
It's not perfectly scientific but pretty much what you can do as an enthusiast with car scanner app and a smart phone.
there are two tests, each covered constant speed at 200kph (effectively 196,x) and each coasting down to 100kph.
One test was done with open air vents and one with closed (taped).
Can you figure out, which was which?
The abstract of the tests is shown in the red markers and shows the differences in percent between test 1 and 2 of the relevant measurements. It shows more or less nothing than a deviation +/- of the expected observational error.
