The partners established a goal of reducing the vehicle mass to that of the Ford Fiesta, while maintaining occupant safety and performance characteristics of the baseline Fusion vehicle.


两家合作方确立的整车的 减重目标为达到福特嘉年 华的重量水平,同时还要 保证驾驶员安全和福星汽 车的运动特性。


principle investigator, MMLV project, Magna International. Magna International is an automotive supplier with 319


manufacturing facilities, including fi ve aluminum vacuum diecasting plants. Magna has worked with its customers on achieving weight savings for specifi c parts and vehicle sub- systems, but the supplier was curious how far weight could be reduced if given the chance to apply weight-saving principles across the entire vehicle. Based on this curiosity, it applied to lead a U.S. DOE-sponsored research program to lightweight a current model production vehicle and invited Ford to be a 50/50 partner. For the program, which started in September 2011,


Ford’s Fusion was chosen as the baseline vehicle. T e Fusion is a top-selling mid-size car, and, in a change from other similar studies, Ford provided the weights and designs of its future 2013 release. Other weight-reduction studies have been conducted on cars that are one or two generations old because the OEM is uncomfortable releasing the current or


Magna国际公司是拥有319家生产厂(其中包括5 个铝合金真空压铸厂)的汽车铸件供应商。Magna 公司与客户在减轻铸件和车辆子系统重量方面开展了 合作,但是,如果有可能将减重的理念应用于整个车 辆,Magna公司对如何进一步减轻车体重量产生了兴 趣。在好奇心驱使下,公司申请带领开展美国能源部资 助的减轻在产汽车重量的研究项目,并且邀请福特汽车 公司作为合作伙伴,双方各占50%。


该项目于2011年9月启动,福特福星被选为基准车 辆。福星汽车是畅销款中型汽车,而且,为了与其他类 似的研究项目区别,福特提供了2013新款汽车的重量 和设计。而其他的汽车减重项目中所使用的车型要早一 代或两代,因为OEM制造商不愿发布当前或先进的车 型技术细节。在此合作项目中,Magna公司和福特汽
