央视网消息：8月21日的《活力中国调研行》关注重庆。重庆最亮眼的产业是什么？从一组数据中可见答案。今年上半年，重庆规模以上 工业增加值比上年增长5.6%，其中汽车产业增加值增速达8.4%，对规上工业增长的贡献率为30.1%。更为突出的是，新能源汽车表现抢眼—— 今年上半年产量48.9万辆，同比增长25%。记者在调研时发现，当地新能源汽车的发展不仅仅是在产量上，还要让这个本身就代表着"绿色"的 产业变得更"绿"。如何做到的呢？先从一辆车的新设计说起。 此前的新能源汽车门环设计，普遍需要几十个零件拼接完成。不仅工艺流程复杂，生产过程能耗还一直很高。 如果想要把这些焊缝都取消变成一个整体的门环，就要找到一种新的材料，既要轻薄又要抗压，还要打破过去习惯的思路，重新设计。北 京理工大学和长安汽车组成的科研团队，每天都往各个企业的生产车间里跑，看不同车型的门环设计。 经过反复实验，用无镀层、抗氧化热成形钢材料可以实现将原来20多个零件的拼接减少到5个零件，能减重4公斤。 相关负责人告诉记者，过去几年，企业新能源汽车销量稳步增长，但同时，他们也面临着产业发展共同的难题：一辆新能源汽车在生产环 节的能耗相对传统燃油汽车要高不 ...
