BMW showcases color-changing car at CES 2022

BMW has demonstrated a color-changing car at CES 2022. The company showed the color adapting technology was on a BMW iX Flow vehicle, with the trick being operated at the click of a button. The iX Flow can change color as its surface is coated in E Ink, the same technology used in e-readers.

E Ink contains millions of microcapsules the same thickness as human hair. Each microcapsule contains positively charged black pigments and negatively charged white pigments. Using an electric field, you can control which pigments are at the car’s surface and this control the color of the vehicle.

Currently, the colors are limited to black, grey and white. However, BMW thinks this lean palette could still prove helpful, particularly for optimising vehicle efficiency. The company suggested that by switching from a black to a white car between winter and summer months, heat from sunlight could be absorbed or reflected as necessary to reduce the need for heating or cooling of the inside of the vehicle.

The iX Flow is purely a concept car. BMW has described the feature as an “advanced research and design project”, so it is unlikely that you will be able to buy a color-changing vehicle soon.
