If you feel it hard to decide what colour car to buy,BMW may have the car for you.The
German carmaker showed off its new colour-changing paint technology in January 2022.With
this technology,you can change the colour of the car by touching a button().
The new car is covered in E Ink panels(电子墨水屏).This is the same technology used in
book readers such as Kindles.The technology works by bringing different paints to the surface
when receiving orders.These orders are controlled by a button in the car or on a phone app.
The car then changes its colour to white,black,or grey.
“White reflects(反射)a lot more sunlight than black,”the company says.“So on hot
days,the temperature of the car can become lower by changing the car to a light colour.And
in cooler weather,darker colours will help the car to take in more warmth from the sun.
The idea of“personalization(个性化)”is very popular right now in the car business..But
when most carmakers are paying attention to the software (inside the car,BMW is
trying to meet customers'different personal needs for the outside of the car.
Just don't expect to see this at your local BMW shop anytime soon:the carmaker says it's
still under development.
