BMW showed off its new color-changing paint technology concept at CES 2022. At the touch of a button, the iX can shift from black and white. The company says it’s the same technology found in e-readers.
A white surface reflects a lot more sunlight than a black one,” the company 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.” In cooler weather, darker tones will help the vehicle to absorb more warmth from the sun.
