The German automaker has just unveiled the world’s first color-changing car that features the new color-changing paint technology package in the automaker’s concept vehicle BMW iX Flow. It relies on E-Ink technology, the same mechanism used on electronic paper in Kindle however, this time it wraps a full car that changes its color on-demand. Somehow, the car you would imagine fresh out of a James Bond movie.
The surface coating of the BMW iX Flow featuring E Ink contains many millions of microcapsules, with a diameter equivalent to the thickness of a human hair. Each of these microcapsules contains negatively charged white pigments and positively charged black pigments. Depending on the chosen setting, stimulation by means of an electrical field causes either the white or the black pigments to collect at the surface of the microcapsule, giving the car body the desired shade.
The innovative paint scheme can be triggered at the touch of a button. Right now, the colors are limited to white, black, and grey.
“A white surface reflects a lot more sunlight than a black one,” the company says. “By implication, heating of the vehicle and passenger compartment as a result of strong sunlight and high outside temperatures can be reduced by changing the exterior to a light color.” In cooler weather, darker tones will help the vehicle to absorb more warmth from the sun.“A WHITE SURFACE REFLECTS A LOT MORE SUNLIGHT THAN A BLACK ONE”
We would like to have this E-Ink technology option to be painted on cars from the dealer, hopefully, the soonest –BMW says this is just an “advanced research and design project.” And the automaker did not mention anything about the efficiency and durability of the new paint tech, we just hope it is rugged enough to withstand the elements.
