Why does the Audi A8 have a multi-material body structure?

I've heard that the Audi A8 has a unique multi-material body structure, but I'm not sure why. Can you explain the reasons for this design choice?

The reason for the Audi A8's multi-material body structure is to improve overall performance and efficiency. By using a combination of materials like aluminum, steel, and carbon fiber, the car is able to have a lighter weight while still maintaining strength and rigidity.

A multi-material body structure also allows for strategic placement of different materials in areas that require more strength or flexibility. This results in a more dynamic and balanced vehicle, enhancing both driving experience and safety.

In addition, the use of different materials allows for better distribution of weight throughout the car, which can improve handling and reduce fuel consumption. This makes the Audi A8 not only a high-performance vehicle, but also an eco-friendly one.
