BMW unveils technology that allows to change exterior color at CES 2022

During a BMW digital presentation, the carmaker reveals its latest electric vehicle, the BMW iX M60. Check out how it's able to change colors, too.

Despite no longer being a secret, this is the official unveiling of the BMW iX Flow featuring E Ink. What is this new E Ink, you might ask? It’s a new method of changing the shade of the car’s exterior, using electrophoretic technology.

The first car to get the prototype E Ink treatment is obviously the BMW iX, which was shown at CES 2022, changing its shade from white to black and back again. More than that, it was able to do it on different body panels, potentially giving the car a two-tone effect.

The E Ink technology is actually a body wrap which, when stimulated with electrical signals, uses electrophoretic technology to change the pigment of its surface. At the moment, it only seems the technology can change color from white to black, as it uses negatively charged white pigments and positively charged black pigments, allowing the electrical signals to choose which are shown. It’s actually a technology similar to that used in eReaders.
