曾几何时，德国工艺、意大利设计、英国血统等，是欧洲汽车工业引以为傲的标签，更是其构筑行业壁垒的护城河。在燃油车时代，这些由百年积淀形成 的专有技术与品牌光环，确实让欧洲车企稳坐全球汽车产业的高端王座。 然而，当汽车的灵魂从发动机与底盘悄然转向芯片与算力，一场深刻的危机早已降临。固执于一切自研的欧洲巨头们，在软件定义汽车的浪潮中频频触 礁，比如项目延期、成本失控、系统失灵成为常态。 直到如今，他们终于放下身段，将目光投向东方，尤其是那些在智能电动车赛道上疾驰的中国企业，才恍然发觉，闭门造车的时代已经终结，开放与合作 才是通向未来的钥匙。 从大众携手小鹏、到Stellantis寻求外部技术输血，一场由痛苦教训催生的觉醒正在欧洲汽车业蔓延。他们终于明白，在软件这场高投入、快迭代的竞赛 中，单打独斗不仅无法赢得优势，反而可能拖垮整个帝国。 欧洲车企的挫折、醒悟 欧洲汽车制造商曾深信，竞争优势源自对核心技术的绝对掌控。这种根植于工业时代的信念，驱使它们在面对软件定义汽车的变革时，第一反应是建立庞 大的内部软件部门，试图将软件能力完全内化。 比如大众集团于2020年高调成立的Cariad软件公司，便是这一思维的典型代表。 ...
