After first teasing it a few weeks ago, BMW today officially unwrapped its color-changing car at CES. The BMW iX Flow, as the German automaker has dubbed this experimental vehicle, is wrapped in what is basically a form of e-paper, which BMW developed in cooperation with E Ink.

As of now, we’re only talking about black and white as color options (with a few shades of grey in between), but that could change over time. And because just like your Kindle’s screen doesn’t use any energy after the content has changed, the iX Flow’s electrophoretic technology doesn’t use any energy either after you’ve set up your preferred color and design.
