On￿the￿F11￿great￿value￿was￿also￿placed￿on￿light￿weight￿construction.￿This￿was￿implemented￿by
intelligent￿use￿of￿high￿strength￿multi-phase￿steels￿and￿high￿strength￿hot￿formed￿steels.￿On￿the￿F11￿the
average￿strength￿of￿the￿body￿materials￿has￿increased￿by￿37￿%￿in￿comparison￿to￿the￿E61.
The￿light￿weight￿material￿significantly￿reduces￿the￿vehicle￿weight￿and,￿in￿combination￿with￿a￿stiff￿body
skeleton,￿provides￿a￿considerable￿contribution￿to:

•

Driving￿stability
• Fuel￿economy
• Reduction￿of￿CO
