    Audi must have done a lot of testing to go with this. I'm worried about a catastrophic failure. Most composites tend to be brittle. I was hoping it was the Carbon Composite Bellows like the ones that Hyperco makes.
    If nothing happens and there is no one around why did it not happen?

    Composites are used in many applications where flex is expected. As long as the flex is within the expected design boundaries it shouldn't ever fail. I could see this providing better road comfort vs. metal springs which would be pretty cool - carbon/fiberglass inherently dampens vibrations better and is used for that quality in many areas - bicycle frames, propellers, the list goes on and on.

    Upon reading how they're made, I wonder how much more expensive they are than steel. The manufacturing process is pretty involved.

    So, German engineering has finally caught up to American engineering? We've been using composite springs, I believe.

    As in iron oxide and steel?

    Is that what they're made of?

    From my understanding the 'Vettes come with composite leaf springs from the factory.

    Corvettes have had fiberglass leaf springs since the 70's.

    I was unaware of these rather impressive looking 'vette leaf springs.

    I was actually just making a (bad) joke. Iron oxide is the "scientific" term for rust.
