2002年，美国能源部（DOE）启动了“自由汽车计划”（FreedomCAR），这是一项与汽车制造商合作的计划，旨在推进高科技研究，生产实用、价格合理的先进汽车，这些汽车有望在短期内显著提高燃油经济性。先进材料（包括金属、聚合物、复合材料和金属间化合物）可以在提高运输车辆的效率方面发挥重要作用。减轻重量是提高汽车燃油经济性同时减少废气排放的最实用的方法之一。在本文中，我们评估了几种汽车平台和先进动力总成技术对汽车质量降低的影响，包括内燃机（ICE）混合动力汽车（hev）和燃料电池混合动力汽车（hev），与传统汽车相比。分析了影响燃油经济性敏感性的主要因素。
In 2002, the U.S. Department of Energy (DOE) launched FreedomCAR, which is a partnership with automakers to advance high-technology research needed to produce practical, affordable advanced vehicles that have the potential to significantly improve fuel economy in the near-term. Advanced materials (including metals, polymers, composites, and intermetallic compounds) can play an important role in improving the efficiency of transportation vehicles. Weight reduction is one of the most practical ways of increasing vehicle fuel economy while reducing exhaust emissions. In this paper, we evaluate the impact of vehicle mass reduction for several vehicle platforms and advanced powertrain technologies, including Internal Combustion Engine (ICE) Hybrid Electric Vehicles (HEVs) and fuel cell HEVs, in comparison with conventional vehicles. We also explain the main factors influencing the fuel economy sensitivity.
