Reduction of carosserie weight • Use of lightweight metals materials in construction of autobody parts
• Light, but good mechanical properties
Light but not cheap – compromise concept has to be found !

Requirements for used materials
• Low weight;
• Sufficient strength for structural stability and durability,
• Good formability;
• Compatibility with assembly operations;
• Good corrosion resistance;
• Recyclability;
• Low material and fabrication costs;

Großserie hergestellt (z. B. Audi A2 und A8, Jaguar XJ, Mercedes Benz
SL oder Opel Speedster). http://de.wikipedia.org/wiki/Karosserie#Aluminium
