4 Vehicle body construction features
4.1 Multi-material mix
Vehicle bodies made of a combination of different materials are
increasingly being used as an alternative to the classic all-steel
body.
The materials most commonly used for the bodywork on today’s
vehicles are:
♦ Steel (various strengths)
♦ Aluminium
♦ Magnesium
♦ Plastics
♦ Fibre-reinforced plastics
♦ Carbon-fibre materials
4.2 Body structures
In addition to the well-known unitary body, there are also other
body structures which are used for Volkswagen Group vehicles.
4.2.1 Aluminium space frame
The special feature of a space frame body is its supporting frame
structure made of aluminium profiles which ensure the rigidity of
the body. Although external body parts such as the roof or wing
panels also play a role in the supporting structure, this is not their
primary function (e.g. Audi R8).
4.2.2 Body-on-frame construction (e.g. VW
Amarok)
Vehicles featuring a body-on-frame construction generally have
a supporting ladder-frame structure which in turn supports the
engine, chassis and body. This construction is primarily used on
utility vehicles and off-road vehicles.
