Introduction
The new Audi A8 is based on an advanced ASF body struc-
ture. With a mix of aluminum, steel, magnesium and
carbon fiber reinforced polymer (CFRP), the load-bearing
structure combines four different lightweight materials.
However, the largest proportion (58%) is represented by
aluminum components which, as cast nodal plates,
extruded sections and sheet metal panels, are the charac-
teristic elements of the ASF construction concept.
Note
The image shows an Audi A8 with a standard wheelbase. The body of the long-wheelbase version (A8 L) is 5.12 in (130 mm)
longer in the area of the ‘B’ pillar.

A rear bulkhead made of carbon fiber saves approximately
50% of the weight compared with its predecessor and helps
make the body rigid and strong in addition to being light-
weight. The intelligent material mix is completed by a dome
strut which is 28% lighter and made of magnesium. Tor-
sional rigidity has been increased 24% compared to the
previous A8.
