From the photo it appears there is a lighting gaffer doing his best to light the car during a photo shoot in advance of —if real — what we'd expect to be an unveil at the Frankfurt Motor Show.
Either way, the complete absence of b-pillar and bright paint indicate this is, at best, a concept. At worst, it's a clever Photoshop job from some dreamer aware the entire automotive world is holding their breath for just such a vehicle. Still, we're hoping against hope this is real.
We have calls into Porsche PR for a comment. We'll see where, if anywhere, that gets us. (Hat tip to Phil!)
