　　宝马日前宣布将从2003年8月1日起，开始受理新款5系列的预约定单。最早于今年10月底交车。将要投放日本市场的新车共三款，分别为“525i”、“530i”及“545i”，均配有汽油引擎。价格方面，525i为570万日元（约合人民币35.6万元）；530i为675万日元（约合人民币42.2万元）；545i为880万日元（约合人民币55万元）。 　　新款5系列中，配备17英寸和18英寸车轮的530i和545i标准配备防爆轮胎，即使爆胎也可行驶一段距离。在17英寸车轮上，采用普利斯通（Bridgestone）生产的侧面加强型防爆轮胎。车体尺寸为长4841×宽1846×高1468mm，轴距2888mm。与现行款相比，长、宽、高分别增加了66mm、46mm及33mm，提供火线 轨道交通维修中心,移门轨道相关，轮距增加了58mm。 　　我国防爆行业真正具备能自主研发产品的企业不过20多家，每年的技术专利和新产品基本是这些行业的优秀企业申请和开发的。而占绝大多数的小型企业基本不具备产品开发能力，有的小企业甚至连工程技术人员都没有，也在盲目生产防爆监控产品，上海道夫自动化仪表工程有限公司,道夫自动化仪表工程,许多企业缺乏市场调研，新产品少，满足不了市场需要，低水平、重复性生产一些低档产品，靠低价格谋取市场份额。这些企业的创新能力的不足，严重影响了我国防爆监控行业整体技术水平的提升，也影响了我国防爆监控产品的国际竞争力。
