These have been floating around on Facebook as of late, and I'm 99% certain they are just cropped, especially since the red one's plate says New Beetle. It's a 21st Century Beetle!
BUT...VW is considering 4 different variants of the Beetle for the 2019 re-skin:
A normal 2-door
The Dune
A Sport Bug with a lower top
And yes, a Beetle with more than 2 doors, but I've read where the proposed model would have a 3rd suicide door like the Saturn coupes or Mazda RX-8 as opposed to a standard 4-door sedan.
They already do. The Porsche Panerama. I doubt whether a 4-door Beetle would be something I'd be interested in, but if VW produced one alongside the "regular" model and it boosted Beetle sales, I'd be all for it.
