13. II-1 Weight reduction
M1 class weight evolution +25% within 15 years due
to Safety Euro NCAP, higher equipment
Coatings develpment participate to weight reduction
UBC example:
Density reduction:
< 1997 High density material 1,4 - 1,6
1997 Low density material 1,0 - 1,2
Actual trend Extra low density 0,8 - 1,0 average gain 2,5 kg
Optimised surfaces & thickness for agression areas:
1997: 8 kg / body
2005: 4 kg / body

14. II-2 Environnement
VOC Emission Car Industry:
Constant evolution of legal requirement actualy 45 gr/m2
European Directive 1999/13/EC
Next is NEC Directive 2001/81/EC
CO2 Emission:
Euro 6
FUTURE: VOC Taxes
VOC « 0 »
