Uli, what do you mean by "internal supporting structure"? Can you give some examples of which parts fall into that category?

My thoughts about CF for the F80 is that it will be used primarily in cosmetic areas like the roof is on today's M3, such as a deck lid, hood, etc. I would expect the rest of the weight savings to come from heavier use of aluminum in the chassis vs. the F30.

I should add - we may also see some CF in the chassis such as perhaps the driveshaft or other easily-formed parts. I am not so sure about the suspension or subframes, but who knows. The question is whether production costs are low enough to mass produce complex parts like that at a pricepoint that will support a $70k vehicle.
