BMW announced a new technology that changes the color of a car with the touch of a button — a nacent innovation of the legendary German automaker. The company unveiled the tech on a concept version of its new 100% electric iX Flow SUV.
A production model of the iX Flow will be available soon, but vehicles with color-changing paint won’t be hitting showroom floors at car dealerships for quite a while — if they ever do. BMW describes the chameleon-like exterior as an “advanced research and design project.”
The trick isn’t done with paint at all, but with specially formed wrapping cut to fit the SUV’s body panels. The wrapping has the same sort of electronic ink technology used in electronic readers. The colored panels were cut precisely to match the shape of the SUV’s body panels and then electric wiring is attached to each section.
The panel surfaces have millions of tiny capsules, each one containing negatively charged white pigments and positively charged black pigments. Electric currents bring one pigment or the other to the surface creating the different shades. Once the color change is completed, the panels keep their tone without needing any more electrical charge.
