低碳钢﹝Low carbon steels﹞

高强度钢﹝High-strength steels﹞

新型高强度钢﹝Modern high-strength steels﹞

超高强度钢﹝Super high strength steel﹞

热成形超高强度钢

﹝Hot-formed super high-strength steels(USIBOR)﹞

铝﹝Aluminum﹞

塑料﹝Plastic﹞

车身本体﹝Bodyshell﹞

•按重量之百分比计算，高强度、新型高

强度和超高强度钢板﹝high-strength,

modern high-strength and ultra highstrength

sheet stee﹞l的使用显著增加

•车体之扭曲刚度﹝Torsional stiffness﹞

增加大约13%

•和W203比较，乘坐厢之刚性和强度﹝

rigidity and strength of the passenger cell

﹞，以及前后部结构之抗变形能力﹝

deformation resistance﹞均进一步提升

•免除MAG焊接缝，改进生产质量

•容易维修－可拆之前后总成，同时挠性

组件﹝flexural members﹞进一步减轻重

量，主要是前面是挤压铝合金断面﹝

extruded aluminum section﹞及后部采用

高强度钢材的设计

ι备注

B柱是采用热成形超高强度钢﹝heat-formed

ultra high-strength steel﹞制造。因此需要维

修时，只能更换整个B柱组件。
