German carmaker BMW has unveiled the world’s first “colour-changing” car at the Consumer Electronics Show in Las Vegas. Reuters reports that the concept car, called the BMW iX Flow, uses electronic ink technology normally found in e-readers to transform the car’s exterior into a variety of patterns in gray and white. When stimulated by electrical signals controlled by a phone app, the material brings different pigments to the surface, causing the car to take on a different shade or design, such as racing stripes. BMW said that though the vehicle displayed at CES could only alternate between gray and white, the technology will eventually be expanded to cover a spectrum of different colours.
