How does the BMW iVision integrate sustainable materials into its design?

I have heard that the BMW iVision uses a variety of sustainable materials in its design, but I'm not sure how this is achieved. Can you provide some insight into the specific materials used and how they contribute to the car's overall sustainability?

The BMW iVision incorporates a range of eco-friendly materials, such as recycled plastics and renewable fibers, into its construction. These materials not only reduce the car's carbon footprint, but also ensure durability and longevity.
