This is certainly not the Ampaire 337 or Electric EEL, which is a converted Cessna 337. It looks like a boundary layer ingestor. Being from Ampaire, it probably is electric or hybrid.
I've tried to find more information about this craft, but failed so far, even from their own website (including the linked page). Google seems to think it's a Learjet. I don't think I've been able to find much, if any other photos of this plane.
The foreground seems to indicate this was a real photo taken from another plane, as you can see window sills, details generally absent in renderings (and many show-off photos). I must admit though, that's not the safest flying around.
Even if it's a rendering, it would probably be a concept. I can't even name the plane yet.
It's beautiful.
