I think this would have a great appeal than the ForTwo by their Smart brand (which might be gone in a decade - per a more recent article). I think it would make for a great Fortwo replacement (perhaps change the Fortwo name if it has a back seat - which it probably has - perhaps called it the Smart FT4? - just thinking out loud).
YouTube has a short video on it.
Here is an interesting article on it by Auto Evolution. They seem to have more photos on it and its relative size. It seems like a very interesting vehicle.
It seems it might not have come about since one sees pickup trucks as the Mercedes Benz current X class vehicles. Perhaps they could call this super mini something else and still be a posiblity? One can hope.
