That sounds like science fiction, but it already works. The BMW iX Flow is coated with a special film. It consists of millions of microcapsules filled with e-ink (electronic ink). This is a technology similar to that used in e-book readers. Each capsule contains negatively charged color pigments in white and positively charged color pigments in black. The pigments can be controlled by means of appropriate electrical impulses and mixed into different shades of gray.
BMW iX Flow: For more individual development
The coating of the BMW iX Flow consists of many small ePaper segments, which the manufacturer adapts to the shape of the vehicle using a laser cut and which can be individually controlled. In this way, you not only change the color of the car completely if necessary, but also in individual areas. There are hardly any limits to the driver’s imagination when designing their car.
Color change should make vehicles more efficient
That sounds primarily like game stuff for well-heeled automobile fans, but BMW also emphasizes the practical use of the color change feature. For example, a light exterior color could reflect more sunlight on hot days and ensure cooler interior temperatures. On the other hand, on cold days, a dark color can absorb more heat. According to BMW, this enables more economical use of heating and air conditioning. That in turn could favor a longer range for electric cars. It is not known when the first cars with e-ink coating will appear on the market.
