The E60 also integrates the familiar side impact
protection gards (steel).
These are bolt on parts that must be replaced
when damaged.
Body Repair
Repairing an aluminum body requires completely new repair methods in body shops with
properly trained personnel, as well as proper tools and equipment.
Aluminum materials can not be "stretched", this rules out the possibility of pulling on a
straightening bench. Components deformed as a result of an accident m m u u s s t t a a l l w
re e p p l l a a c c e e d d , which incurs more extensive training, tools and assembly procedures than is the r
case with steel bodies.
Using the frame rail as an example, deformed E60 aluminum components must be cut off
at permanently defined points and replaced by new components.
Special insert repair elements made of aluminum
are required to ensure that the replacement parts
are safely and securely held in place.
The insert element for repairing aluminum (top
left) is inserted into profile chambers and then
expanded into place by bolts (refer to the E60
SIP for more details).
