Turns out it's a massive RC car.
Indeed, the crowds were almost as big as the Vision 6 is. It measures a gargantuan 5.6 meters (222 inches) from stem to stern, making it slightly longer than the Rolls-Royce Phantom Coupe, the biggest two-door currently on the market.
It’s a dramatically swoopy thing, recalling Maybach’s Golden Age of the 1920s and 1930s, when its chassis were bodied by some of the finest coachbuilders in the world. The epically long bonnet, the perfectly rounded rear, the exquisite detailing; it’s all redolent of an era when a car’s styling was limited only by the designer’s imagination and the owner’s wallet.
Power comes from four electric motors - one on each wheel - producing a combined total of 738 horsepower (550 kilowatts), with an 80 kilowatt-hour battery pack that’s good for a range of 322 kilometres (200 miles).
Now, it’s no secret that concept cars often don’t actually contain the powertrains their makers specify - indeed, the wheels might not even turn - and that’s likely to be the case with the Vision 6. But it will move under its own power because it is, in fact, a massive RC car.
Youtubers Marchettino (above) and Brian Zuk (below) were at Pebble Beach and filmed the Vision 6 being maneuvered with what looks like an off-the-shelf RC controller. It's a somewhat incongruous sight, but the guy operating it undoubtedly had the coolest job at the show.
