This is how the crazy technology works.
Just yesterday, we saw a video of a BMW iX changing color on the fly at this year's CES. Now, the brand is dropping the details on how it managed to pull that off and states that it could be coming to production cars. It adds that this is just another feature owners will have access to, to further express their individuality.
It turns out that this special iX Flow model was covered with a specially developed wrap called E Ink that has been designed for the shape of the SUV, as it accommodates all contours along its surface. This application then receives a series of electrical signals which manipulate an electrophoretic technology, thus bringing out different color pigments to the surface. With this, the skin of the body takes on contrasting coloration.
BMW says that this is an important feature because, since the beginning of the automotive age, car colors have been an integral part of the owner's personality. The brand also reminds us that it already offers a broad spectrum of color options with new shades set to be added on an annual basis, to reflect the varying characteristics of its current consumer base.
While an official introduction date of the E Ink technology has not been stated, BMW assures us that it is pushing the development forward so that this can be selected as an option both inside and outside of future products. BMW says potential customers will be taken to a whole new level when it comes to specifying a new car in a truly unique way.
Not only does it look cool, but BMW claims that the E Ink wrap is also a sustainable option. Seeing that white shades reflect light better than dark ones, it's understood that drivers can simply change the color of the car in warmer conditions to reflect more light and rely less on the climate control system. With darker shades having the ability to absorb more heat, the opposite can be done in cooler conditions.
Furthermore, the E Ink tech itself doesn't need a constant flow of energy to maintain the chosen shade. All that is required is just a light jolt. This innovative wrap is already being applied to devices such as eReaders but for the one applied to this iX Flow, millions of microcapsules have been used to surface coat the finish.
