Mercedes-Benz will soon be pulling the wraps off the Vision EQXX concept, a vehicle with adaptive aero designed be as aerodynamically efficient as possible. This slippery study, which will debut on January 3, 2022, has a claimed range of 1,000 kilometers (621 miles) on one charge and it will rely on extra solar power to achieve it.

The automaker doesn’t go into detail about how big an impact this extra solar power will have on the vehicle, or where the solar cells will be located, but this study apparently previews a production model. This essentially means Mercedes is working on a rival for the Lightyer One set to be revealed in its final production form next year.

The vehicle’s design is dictated by the requirement for it to be very slippery, but Mercedes assures us that it will still be great to look at too. And judging by the glimpses that we’ve already caught of the EQXX, we can certainly say there is visual appeal in its long, low, tapering sedan shape.
