CES: BMW shows the car changing color

CES is always full of cool technology concepts, the latest in the line is BMW with its car that can change color. It is The Verge who has taken a closer look at the car, which has a lot in common with the Kindle. By using e-ink, ie the same technology that is found in tablets, it is possible to make the car change color.

According to BMW, the coating on the BMW iX Flow has many millions of microcapsules, with a diameter corresponding to the thickness of a human hair. Each of these microcapsules contains negatively charged white pigments and positively charged black pigments. By stimulation with the help of an electric field, either the white or the black pigments can accumulate on the surface of the microcapsule, giving the car body the desired shade.

The color change is made at the touch of a button. At present, the colors are limited to white, black and gray. But despite the limited range, BMW says electric vehicles can benefit from it: “A white surface reflects much more sunlight than a black one,” BMW writes in a press release. “To change the exterior to a light color. In colder weather, darker tones will help the vehicle absorb more heat from the sun.”

When the technology is available for passenger cars is unclear, however. Below you can see a video of the BMW iX Flow
