BMW unveiled during a presentation at CES 2022 a new car model that allows the driver to instantly change the color of the vehicle, with just a touch of a device.
it is about the BMW iX Flow, which has, among other characteristics, the technology E Ink, able to change the color of the vehicle in seconds.

The model was presented to the public at CES 2022 — the world’s leading electronics fair, which takes place this January in Las Vegas.
“In the future, BMW car owners will be able to change the color of their vehicles with just the press of a button,” said Stella Clarke, BMW iX project leader.
“We are taking personalization to unprecedented levels,” he added.
Technology
According to the company, the technology is similar to those used in e-Book screens. The car’s paint is made up of millions of microcapsules, which have a diameter equivalent to the thickness of a human hair.
BMW reports that each of these microcapsules contains negatively charged white pigments and positively charged black pigments.
“Depending on the chosen configuration, a stimulus through an electric field is enough for the white or black pigments to accumulate on the surface of the microcapsule to give the car’s bodywork the desired tone”, explained the manufacturer.
Adaptation to the external environment
One of the new features of the E Ink technology is that it can be adapted by the owner of the BMW iX based on their preferences, but also based on weather and climate conditions.
On days with strong sunlight, for example, a white hue reflects sunlight better, reducing the heating of the vehicle and the passenger compartment caused by strong sunlight and high temperatures.
On days with colder environments, a dark external surface is recommended, as it will help the vehicle to absorb noticeably more heat from the sun.
“In both cases, selective color changes can help to reduce the amount of cooling and heating needed for the vehicle’s air conditioning,” said BMW.
“This reduces the amount of energy that the vehicle’s electrical system needs and, with it, the vehicle’s fuel or electricity consumption as well. In an all-electric car, changing the color according to the weather can also help to increase the range.”
According to the statement, the E Ink technology does not need energy to maintain a constant state of the chosen color. Electric current flows only during the short color change phase.
