German carmaker BMW has unveiled the world's first "colour-changing" car at the Consumer Electronics Show (CES) in Las Vegas.
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.
"This is really energy efficient colour change using the technology E Ink," said BMW research engineer Stella Clarke. "So we took this material - it's kind of a thick paper - and our challenge was to get this on a 3D object like our cars."
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.
