Passenger cell BMW i3
(CFRP)
The body of this electric vehicle
has a two-unit conguration. The
upper unit (the passenger cell) is
made of CFRP (Carbon-ber-
reinforced polymer), whereas the
upper unit (the drive module) and
the space frame are made of
Lithium-ion battery aluminum extruded shapes. The
door panels also have extruded
aluminum built-in frames.

Subframes
A subframe is a structural component that is a separate structure Forged aluminum alloys

within a larger monocoque. It carries certain components, such
as the engine drivetrain or suspension. Subframes need to have
high rigidity and shock-absorbing capabilities. Because of their high strength,
high cyclic stress, and high
reliability, forged aluminum
alloys are used for structural
parts such as suspension
arms. Forging techniques
include hot forging and cold forging, and alloys can be
selected to match the properties of each part.
