BMW has premiered a new, future-focused body wrap that allows the driver to alter the exterior hue of their BMW with the use of digitisation. Said Adrian van Hooydonk, head of BMW Group Design, ”The BMW iX Flow is an advanced research and design project and a great example of the forward-thinking that BMW is known for.” Watch the video below…

As seen here on the iX Flow, the fluid colour changes are made possible by a “specially developed” body wrap that is tailored to the contours of the emissions-free SAV (sports activity vehicle). So, how does it work? Well, when stimulated by electrical signals, the electrophoretic tech brings different colour pigments to the surface. This causes the “body skin” to take on the desired colouration. 

The electrophoretic colouring is based on a technology developed by E Ink, a brand of electronic paper display technology commercialized by the E Ink Corporation. The surface coating of the iX Flow features “many millions” of microcapsules which, the German automaker says, have a diameter equivalent to the thickness of a human hair. Each of these microcapsules contains negatively charged white pigments and positively charged black pigments. 

According to the Munich-based car manufacturer, “Achieving this effect on a vehicle body involves the application of many precisely fitted ePaper segments.” Laser-cutting technologies guarantee high precision in generating each segment. After the segments are applied and the power supply for stimulating the electrical field is connected, the entire body is warmed and sealed to guarantee optimum and uniform colour reproduction during every colour change.
