F25�Bodyshell
2.1.1.�Introduction The�F25�body�is�comprised�mainly�of�strong,�lightweight�materials.�This�is�achieved�with�the�intelligent application�of�higher-strength,�multi-phase�steels�and�super-strength,�press�hardened�steels.�On�average,�the�strength�of�the�body�materials�used�for�the�F25�is�27%�higher�than�the�E83. The�construction�with�lightweight�materials�makes�a�decisive�contribution�to�reducing�the�overall�vehicle�weight�which�results�in�a�significant�contribution�to�the�following:

•
Driving�dynamics
•
Reducing�fuel�consumption
•
Reducing�CO2�emissions
•
Passive�safety.
F25�Introduction 2.�Body Highlights •
High�proportion�of�multi-phase�steels�(14�%�of�the�bodyshell�weight)
•
High�proportion�of�press�hardened�steels�(4%�of�the�bodyshell�weight).
The�higher-strength�multi-phase�steels�and�super-strength�press�hardened�steels�ensure�maximum strength�of�the�passenger�safety�cell�with�low�weight,�thus�making�a�huge�contribution�to�passive�safety. In�the�case�of�the�press�hardened�steels,�an�innovative�development�with�passive�corrosion�protection is�used.�This�development�is�unprecedented�as�suitable�press�hardened�sheet�metal�materials�with sacrificial�corrosion�protection�have�not�been�available�in�the�market�until�now.�The�development�of press�hardening�technology�means�that�a�series-compatible�procedure�for�the�manufacturing�of�galvanized�press�hardened�components�is�now�available. During�this�process,�galvanized�sheet�steel�is�initially�cold�worked�then�heated�to�roughly�1652°F (900°C).�They�are�then�cooled�down�right�away�to�roughly�158°F�(70°C)�and�hardened�within�a�few seconds�in�the�pressing�tool�with�integrated�water�cooling�directly.�Following�this�procedure,�the�minimum�elastic�limit�of�the�components�is�significantly�higher�than�1000 MPa. Components�manufactured�in�this�manner�can�be�used�in�areas�where�moisture�is�present�without corrosion�of�the�base�material�occurring.�Additional�corrosion�protection�measures�are�no�longer�required�for�this�steel.
2.1.2.�Materials A�modern�vehicle�body�must�meet�a�great�many�requirements.�Despite�small�outer�dimensions,�it should�provide�a�passenger�compartment�that�is�a�large�as�possible.�In�the�event�of�an�accident,�passengers�must�be�protected�against�injury�as�effectively�as�possible.�The�torque�that�is�generated�also�means�that�all�assemblies,�e.g.�the�engine�and�transmission,�rely�on�the�body�for�support.�Furthermore,�the�body�must�have�high�static�and�above�all�dynamic�rigidity�in�order�to�guarantee�the�outstanding�driving�characteristics�that�are�typical�of�BMW. Last�but�not�least,�the�supporting�structure�of�the�vehicle�must�be�durable�over�the�long�term�and,�in the�event�of�an�accident,�it�must�be�possible�for�repairs�to�be�carried�out�at�a�reasonable�cost�and�with a�minimum�amount�of�effort. In�order�to�meet�all�of�these�requirements,�BMW�pursues�the�strategy�of�creating�each�component from�the�material�best�suited�for�its�function. The�word�"steel"�is�ultimately�an�umbrella�term�that�describes�the�large�number�of�alloys�with�widely varying�properties�that�are�used.
