Porsche Panamera convertible
This patent picture shows a 4 door car.
Which is pretty incredible and weird. The structure of the car would have to be so strong.
There seem to be some kind of a brace right behind the front seats, but I just wonder if would be enough.
Chrysler did show a 300 convertible concept a few years back, the Helios 300 by ASC. And it was a 4 door. I remember it also had something right behind the front seat as well that, they claimed, allowed for a 4 door convertible.
If it ever happens, a 4 door convertible Panamera will sure turn many heads….
