Material composition
Fig. 8 shows the material composition of a Golf VI 2.0 TDI in accordance with the VDA
(German Association of the Automotive Industry) standard 231-106 for material classification
[VDA 1997]. 16 The graph indicates the material composition of and material
shares in the vehicle assessed.

65 %
The Golf VI 2.0 TDI consists of 65 percent steel and iron materials and 17 percent various
plastics (polymer materials). It also contains about six percent light alloys, such as
aluminium and magnesium. Nonferrous metals, such as copper and brass, account for
about three percent of the car‘s materials. The composite and other materials, which
account for approximately three percent of the vehicle by weight, include ceramics and
glass, renewable raw materials and materials which are inseparably joined, e.g. metal
coated with plastic. Operating fluids, such as oils, fuel, brake fluid, coolant and washing
water combined, account for about five percent of the total vehicle weight. The remaining
approximately one percent is made up of process polymers such as paints
and adhesives. The share of electronics and electrics is extremely low because the
materials used in these components have been itemised in detail on the basis of the
16 Unladen weight in accordance with DIN 70020 without driver and with the fuel tank filled to 90% of capacity.
