CO2 Regulations in the EU
In an integrated approach, CO2 emissions will gradually be limited to 120g/km (“integrated approach”: carmakers to achieve 130 g/km through technical improvements, remaining 10 g/km shall come from complementary measures): 2012: 65% of new cars sold have to average 130 g/km CO2 2013: 75% ~ 2014: 80% ~ 2015: 100% of new cars sold have to average 130 g/km CO2 Fines per car sold when exceeding target: Between 2012 and 2018: EUR 5 for the 1st gram of CO2 EUR 15 for the 2nd gram ~ EUR 25 for the 3rd gram ~ EUR 95 for the 4th and each subquent gram From 2019: EUR 95 for each gram over the target Influence on vehicle: more lightweight solutions are required

PATCHWORK
Advantage : Crash relevant parts High bending and torsion loads Local adjustable part properties Weight reduction Reduced tooling costs No tolerance adjustment needed
Advantage: Continuous variable blank thickness Coil to Coil production Different thickness with consistent transitions Thickness tolerance +/-50µm Amount of wall thickness changes not cost influencing Good crash performance Weight reduction
characteristic: production of hot formed pre-coated components of complex geometry with adjusted wall thickness by forming of 2 sheet metals in one step.
