Last year, Mercedes-Benz revealed the Vision Mercedes-Maybach 6 concept , the closest thing you could get to a luxury yacht for the road, and now the German carmaker is back with the convertible version.

The interior is covered in Crystal White leather and paired with a wooden floor laced with aluminum inlays — another yachting reference.

The real eye-catcher, however, is the transparent center tunnel filled with blue fiber optics that’s designed to visualize the car’s electrical energy flow.

As Mercedes describes it, “a light wing flows in a curve across the door trim and the center tunnel into the seat landscape, creating a 360-degree open-air luxury lounge.”

There’s almost zero chance the Vision Mercedes-Maybach 6 Cabriolet will actually enter production, so those attending this year’s Pebble Beach Concours d’Elegance will have one of the few opportunities to see it in person.
