affecting the stability of the occupants’ cell.
The stable crosslinks in the bumper mean
that even if the impact force is only felt on
one side, the side facing away from the
impact can still be included in the
deformation process.
The main concern at the rear end of the car is
to ensure that the shape of the vehicle is
stable around the fuel system.
Careful use of extruded profiles and
aluminium die-cast components

means that in a crash situation the rear end of
the vehicle deforms in different stages from
the end of the vehicle to the occupants’ cell.
The strain on occupants is clearly below the
legal limits.
The aluminium bumper consists of a multi-
chamber hollow profile and forms a weight
and force-optimised crash unit together with
the longitudinal member system and the
structure of the occupants’ cell.
Planned deformation of the front end
dissipates the impact energy without
