A special knowledge and special skills are required 
to repair aluminium bodyshells. A prerequisite for 
successful body repairs is participation in the rele-
vant training courses.

Particularly for welding work, certification of 
employees according to international standard DIN 
EN ISO 9606-2 is important.

Car body safety concept

Head-on collision, side impact and rear collision

Likewise, in terms of crash safety, the new TT makes 
no compromises. The front beams consist of alu-
minium extruded sections and aluminium castings. 
In combination with the front beams and a sub-
frame, they reduce and distribute the forces which 
act on the car body during a head-on collision. 
Large-sized beams in the rear end protect the occu-
pant cell.High-strength aluminium beams in the 
doors provide side impact protection. The alumin-
ium bonnet is designed to all requirements for 
pedestrian safety.

The simulation provides information on the collision 
behaviour of the body structure at a very early stage 
in the development process. For this purpose, calcu-
lations are done on the basis of the available car 
body data using the Finite Elements Method. The 
results are incorporated into the ongoing design 
process, thus allowing the body structure design to 
be optimised in respect of the relevant crash loads.

Euro NCAP head-on collision (64 kph with partial overlap) 

To check the theoretical results and to meet statu-
tory requirements, actual tests are conducted. 

Various test conditions are simulated on the basis of 
the applicable standard.

Car body safety concept

Pedestrian safety

When designing the bonnet, importance was 
attached to a stable design which yields to absorb 
head impacts. This is achieved by the honeycomb-
like structure of the car body inner panelling.

383_034

The overall concept provides for deformation zones 
between the bonnet and the units or car body struc-
tural parts.

To reduce leg impact force at the front end, the 
bumper cover has been decoupled and an impact-
absorbing foam part has been integrated between 
the bumper beam and bumper cover.

383_044

Pedestrian safety is an increasingly important fac-
tor. Various measures were implemented in the new 
Audi TT in order to meet the safety requirements.
