近日，公安部发布强制性国家标准《机动车运行安全技术条件》征求意见稿（以下简称"征求意见 稿"），其中提到"乘用车每次上电/点火后（发动机自动启停除外），应处于百公里加速时间不小于5秒 的默认工作状态"。 该规定引发网友热议。许多人表示支持，认为买新能源车更安全更放心了；但也有人担心，这样的 限制会影响造车技术发展。 在燃油车市场，百公里加速时间是一个很重要的动力参考指标，反映了车辆的加速能力和动力系统 性能。高性能燃油车配置更强的发动机和变速箱，百公里加速时间可以更短。 百公里加速时间是指汽车从静止状态全力加速至100公里/小时所需要的时间，通常认为该时间越短 汽车加速能力越强。"技术党"将其视为体现汽车性能的一个重要指标。 这是汽车行业首次在百公里加速上划定时间红线。那么，征求意见稿为什么将这个时间红线规定为 5秒？目前在售车百公里加速水平如何？5秒门槛将对产业发展有何影响？科技日报记者为此采访了行业 相关专家。 第一问：为什么规定为5秒？ 征求意见稿编制说明中提到，近年来，我国新能源汽车、具有辅助驾驶功能的乘用车渗透率快速提 升，相关交通安全隐患和事故也逐渐增多。但目前标准相关技术要求滞后，难以满足汽车产 ...
