These are NACA ducts.
https://en.wikipedia.org/wiki/NACA_duct
They are a way to direct airflow to an area without an increase in drag and frontal area.
On this mockup, they are there to channel air into the remaining wake to decrease it's size.
It's a bit O.C.D., but every bit of drag reduction helps.
I also like the look of N.A.C.A. ducts.
I had them on my box cavity / Kammback.
I tested them, and airflow velocity through them was as good as from the edge of the roofline.
Unfortunately, I did not have a chance to test to see if they reduced drag, since I had the car stolen.
Yes ! You read that right - someone actually stole the car.
Imagine that L.O.L.
