How to reduce weight of Body
* Use High Strength Steel; 980MPa, Hot stamping
* Apply Laser Welding
* Use Innovative Press Machine
* Apply Plastic Parts with new Technology
* Optimize Body Structure by CAE

Technology for weight reduction
Over 980MPa material increases after 2012
drastically.
Main area are zones to meet Side Impact and
Roof crash and Fr/Rr Impact requirements.

Parts are simulated in feasibility stage of stamping process.
The objective is to reduce problems which may occur during mass production.
Develop in stamping process is to get the best quality of finishing parts.
