Why are the carbon fiber components in the BMW i7 important?

I've noticed that the BMW i7 uses a lot of carbon fiber components in its construction. Are these just for cosmetic purposes or do they actually serve a functional purpose?

The carbon fiber components in the BMW i7 serve a very important purpose. They are not just for show, but actually play a vital role in the car's performance and efficiency.

As someone who works in the automotive industry, I can tell you that carbon fiber is one of the strongest and lightest materials available. This means it can help reduce the car's weight, which in turn improves its handling and overall driving experience.
