The iX Flow has electrophoretic paint, which does not use energy continually like a display would. Instead, the E Ink only requires power when transitioning from one finish to another. There are additional varieties of this technology that allow greater color variety, but they would need more engineering to make them function. However, BMW claims that they are researching towards further developing this technology.
Stella Clarke, the Project Manager of the BMW iX Flow, was interviewed to learn more about the BMW iX Flow and its possible future applications. The BMW iX Flow was on show this weekend at the Villa d’Este Concorso d’Eleganza 2022. As Clarke says, it’s not some novel technology; it’s the same technology used in eReaders. However, scaling it up and transferring it to a flexible wrap that can subsequently be applied to a car would undoubtedly need some costly engineering, particularly in order to make such an application cost-effective.
Of course, it’s conceivable, but determining how to accomplish it on a wide scale, and if it’s even profitable, is step two in Clarke’s approach. The first step was to create three interesting prototypes, which Clarke and her team completed.
