I've seen a number for it. As far as I can remember, the 'early' versions
(5 years ago) were weighing in at 35 kg. The book I have also showed the
ASF being carried by two women.

Audi's technology is and won't be proprietary for long. Apparently Alcoa
is working with other, anonymous manufacturers on incorporating the new
aluminum manufacturing techniques into their vehicles. So there will soon
be more aluminum competetion.
