Body
The Audi A8 ´03 sets new standards in its
class by combining lightweight construction
with outstanding stability. This is achieved
through the use of innovative Audi Space
Frame technology for the body design of the
Audi A8.
The technical progress reflected by the
unique body concept stems from the
consistent implementation of experience
gained from the aluminium Audi A8 and A2
models.

Based on the findings obtained from these
vehicles, it was possible to further reduce the
number of body components and
significantly increase the level of automation
in the production process as compared to the
Audi A8 predecessor model.
The static torsional rigidity of the new Audi A8
body is 60 % higher than that of the previous
Audi A8 body.
A crucial contribution is made to the
increased rigidity level by the advanced
Audi Space Frame structure.
Characteristic features of the new structure:
– Large castings with numerous integrated
functions and a high degree of joint
strength
– IHF* sections – optimum cross sections at
all locations, for example at side of roof
frame
– Sheet metal panels with high levels of local
rigidity thanks to the use of special
technologies designed to achieve differing
functional cross sections and structures
*IHF = Internal high-pressure forming
