Body
A body with a high static and dynamic rigidity is the
requirement for good vibration behaviour and
excellent driving properties.
This is achieved by using high, higher and highest-
strength sheet qualities as well as
THERMOFORMED
SHEETS
in conjunction with modern joining methods
like laser welding and structural adhesive joints. The
use of thermoformed sheets, in particular, has
increased the stability of the body without making it
heavier.
The following components are made from highest-
strength sheets:
- Inner A-pillar
- Seat consoles
- Sills
- Rear longitudinal members
Highest-strength tubes are fitted in the upper area of
the doors and under the rear seat bench.
Thermoformed sheets are used:
- in the front bumper cross-members
- in the A-pillar reinforcements and in the
front windscreen frame
- in the door reinforcements
