The original Maybach 6 gave us a glimpse at what Mercedes' ultra-luxury brand's flagship coupe could be. The Vision Mercedes-Maybach 6 Cabriolet does the same for a drop-top. It's powered by an electric drive system producing 750 hp with a range of over 200 miles. Similarly advanced is the interior, with a display strip that runs from the rear across the doors and all the way across the dash. Most striking, however, is the art deco-inspired exterior design, with its oversized hood and grill, yacht-like boat tail rear, 24-inch alloy wheels, and 20-foot length. Like its hard-topped sibling, it's unlikely to see production anytime soon.
