571 - Door

The doors have been modified in the following areas in relation to the predecessor with the objective of further improving crash safety: In order to reinforce the passenger cell in the event of a frontal or offset crash, the upper load path has been optimized. The upper load path distributes the energy acting on the body in the event of a frontal crash very effectively between the front and rear parts of the car via the door. The accomplish this, the upper part of the door has been strengthened by the high strength steel door channel reinforcement (1). In the event of a crash, this reinforcement transmits the attendant forces via a support on the rear side section to the car. This has further improved the deformation behavior and the integrity of the passenger cell (important protecting passengers).

Door reinforcement (2) consists of high strength steel profiles and is also integrated into the door construction. In conjuction with rigid side structure, it provides for increased penetration resistance and improved side protection. The door arrested has been equipped with an additional, third index position for more precise positioning of the doors during opening.







The doors are modular in structure. The side airbag, loudspeakers, wiring harness, power window motor, etc. are attached to the aluminium inner door paneling. The inner paneling is screwed to the door.







The window lifter assembly is attached to the inner door paneling and fitted in the appropriate mountings at the bottom of the door shell.







The door seal comprises the mirror the seal, the interior door channel seal and the door fold seal. The door seal is slotted into place in the area of the door channel and is held in place by clips in the door fold. The outer door channel seal is slotted into position.

The door mirror assembly is mounted is to the mirror triangle by three screws. The rear cover conceals the point at which the door channel reinforcement is screwed into place at the rear. The door window is inserted in the fixtures on the window lifter from above sliding it through the door panel.
