E93 Body Construction - BMW 3-series convertible Complete Vehicle Workbook

E93 Body Construction

As with all current BMW models, there is an extensive use of high
strength steels.
There is an "intelligent mix" of materials to provide the lightest
possible weight with the best possible strength.
The color illustrations above, demonstrate the distribution of the
materials. For more information, refer to the E93 complete vehicle
reference material in TIS and ICP .
The design of the E93 also allows for an increase in torsional
rigidity over the E46 iC. The chart at the right illustrates these
figures.
