Plenum chamber
One application area for special steel is the chassis
connection in the proximity of the spring and shock
absorber seat.
It was possible to reduce the wall thickness of the
respective parts from 2.5 to 1.4 mm.
The resulting loss of local rigidity was offset by
creating an optimized profile.

Special steel (600 - 900 N/mm²)
tailored blanks
Aluminium
In addition, a tailored blank is fitted in the plenum
chamber.
This ensures the highest possible energy
absorption in the event of a crash.
At the same time, the necessary rigidity and
stability are ensured during normal driving.
Transverse rigidity is ensured by a rolled sectional
bar as an additional reinforcement.

Wheelhouse
To ensure an optimum introduction of the crash
energy from the front of the car into the passenger
compartment, special steel components were used
in the proximity of the wheelhouse.
