For all the talk about the maturity of the electric car, it still has a ways to go before it can cover all the bases in the automotive ecosystem. While you can buy a few electric sedans, a handful of electric crossovers, and even an electric pickup truck, there are plenty of automotive niches yet to be blessed with batteries.

For example, there are no electric minivans, although Volkswagen’s ID.Buzz will check that box when it goes on sale next year. Electric convertibles are equally elusive. The EV that proved you could combine a bunch of laptop cells to power a car was the original Tesla Roadster, but it went out of production almost a decade ago.

It makes sense—the convertible market is a small one, and as startups and established automakers build out their battery-electric product portfolios, they’re starting with models that will sell in volume and make them some money. But that hasn’t stopped Polestar from imagining what its droptop might be with a stunning new concept car called the O₂.
