How do the microcapsules get to the surface of the car? For this purpose, ePaper foils are precisely cut, which are then applied to the body. After applying the film segments and connecting to the power supply, the entire body is heated and sealed in order to ensure a uniform color rendering on the entire body with every switching process. “In the future, digital experiences will not only take place on displays.

The show car can switch from black to white, but other colors are also conceivable, explains the project manager, Stella Clarke.

In contrast, a dark vehicle absorbs more heat from sunlight at cooler temperatures.
