While most concept cars never make it to the production stage, the ideas and innovations within them often do. Take Hyundai’s Mobile Eccentric Droid (above) for example. We may never see it out on the street, but a vehicle that bundles steering, powertrain and brakes into each individual wheel, for unparalleled agility? That’s the kind of concept we can get behind.
With that in mind, check out five concept EVs with very different visions of the future — and daydream about what might still come to be.
Mercedes-Benz Vision EQXX

Mercedes wants to be, well, the Mercedes of electric car manufacturers. Consider the Vision EQXX the brand’s statement of intent. This concept hypermiler achieves a range of 620 miles on a single charge, enough juice to drive from New York to Cincinnati. It does this using revolutionary aerodynamics — its 0.17 drag coefficient makes it more slippery than an American football — and unprecedented efficiency, sending an incredible 95 percent of its battery energy to the wheels, versus about 30 percent for the power coming from the engine of a conventional car. Mercedes won’t build a production version, but the concept’s tech will reach reality. That should put even Tesla on notice.
