Bmw iX Flow, the chameleon concept with the body that changes color

Cars News

Future owners of electric BMWs such as Diabolik, the comic book thief created by Angela and Luciana Giussani. The new digital universe, “without borders” recalls Pieter Nota, number one of the Elica brand, will allow customers to change the body color of their zero-emission cars exactly as the two sisters had imagined that the imaginary criminal could do. . The regions of the second, escaping the police, are less noble than those of the first, in favor of which the extreme amplification of personalization is assumed. The solution was anticipated on the occasion of the Consumer Electronic Show in Las Vegas, even if the speakers of the German company spoke from the headquarters in Munich.

The chameleon concept, the BMW iX Flow, was developed with E Ink. At the push of a button, drivers can change the exterior tone. “We bring car bodywork to life,” summed up Frank Weber, head of premium brand development. At least formally it is not just a question of satisfying a potential whim of the vehicle owner because the exterior color can also affect efficiency by reducing energy consumption. “Overheating of the vehicle and passenger compartment caused by strong sunlight and high outside temperatures can be reduced by changing the exterior to a light color,” suggests the manufacturer. Which he also remembers as “in lower temperatures, a dark outer coating will help the vehicle absorb more heat from the sun.”

The secret is in the electrophoretic coloring coating, based on Taiwanese E Ink technology that mimics the look of ink in eReaders. The same principle of the so-called electronic card has been extended to the paint applied to the bodywork. Thanks to millions of microcapsules (the diameter is equivalent to the thickness of a human hair) which contain negatively charged white pigments and positively charged black pigments, a simple pulse is enough to modify the electric field causing one or the other to collect on the surface with the consequent change of hue.

BMW explains that “to achieve this effect on a vehicle body requires the application of many precisely fitted ePaper segments.” The manufacturer also talks about specific “generative design algorithms” and laser cutting technologies. At the end of the application of the various parts, it is also essential to heat and seal the bodywork to ensure “optimal and uniform color reproduction during each change”. It seems obvious that this option will arrive on production cars, but there are no indications on the timing. Nor are there any costs involved, even in the case of scratches.
