Yes, it is not a Porsche - far from it.
However this community is extremely knowledgeable and someone may know this car or at lease knows where there are more photos.
It is, imho, a very interesting approach to combining a relatively new style with old. I suspect a C4 corvette and/or Caddy XLR in its DNA and the tri-5 ('57, I think) fins work surprisingly well (again, imho).
What I really want is a front view to see if the retro cues were also carried through to the front (grille?) of the car.
Fyi, this is a photo from the October 2018 Caffeine and Octane in the Atlanta, GA area.
