In 2022, BMW unveiled the groundbreaking BMW iX Flow, the world’s first color-changing vehicle. The prototype is wrapped in “E ink,” a 12-volt electronic coating that operates similarly to a Kindle display and requires minimal energy to sustain, even in direct sunlight. Developed in collaboration with a Taiwanese company, the flexible material has thus far been produced in grayscale, with plans to introduce color in the future. This innovative invention holds immense potential, not only for energy efficiency in a warming climate but also for advertising and informational displays. Beyond its practical applications, the BMW iX Flow also offers a fun and visually captivating element, making it a highly appealing technological advancement.
