We are not huge motorheads, but even we were excited when we caught sight of the new BMW iX which was unveiled at the 2022 Consumer Electronics Show in Las Vegas last week.

Having developed a body wrap for its all-electric, concept version of the BMW iX, the German automaker demonstrated new colour-changing “paint” that relies on E Ink, a technology more commonly used in electronic readers like the Kindle and our old favourite, the now defunct Pebble watch

E Ink contains millions of microcapsules, each with a diameter equivalent to the thickness of a human hair,  which contain negatively charged white pigments and positively charged black pigments suspended in liquid. The colour changes depending on whether a negative or positive charge is applied, causing either the white or the black pigments to collect at the surface of the microcapsule. At the touch of a button, a driver can almost instantaneously change the shade of the car’s exterior, allowing the colour to shift between black and white or even light and dark stripes giving the car a chameleon-like quality.
