LAS VEGAS: When you’re buying a dream car, yet indecisive about the colour, the BMW iX Flow is the answer.

The German automaker showcased its new colour-changing paint technology at the 2022 Consumer Electronics Show in Las Vegas.

The BMW iX can change its appearance digitally. The body is laminated with an electrophoretic film containing microcapsules the diameter of a human hair. Each capsule contains differently charged white, black or coloured particles, which become visible when an electric field is applied. This creates what is known as an Electronic Paper Display.

However, you would not be able to see on display at showrooms anytime soon, as the automaker says this is just an “advanced research and design project”.

The German automaker claims that the BMW iX Flow is a pioneering project in a field that opens up entirely new possibilities for car design and personalisation.

The paint scheme could be changed with just a push of a button. Right now, the colours are limited to white, black and grey, the Verge reported.

The concept of “personalisation” is very popular right now in the auto industry. But while most of the efforts are focused on the interior, tweaking the software to remember the driver’s preferred vehicle settings, BMW is bringing the concept of personalisation to the exterior of the vehicle, the Verge said.

“A white surface reflects a lot more sunlight than a black one,” the automaker 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,” It added.

In cooler weather, darker tones will help the vehicle absorb more warmth from the sun.
