麦格纳国际和福特汽车公司开发的多材料轻型汽车 (MMLV) 是美国能源部项目 DE-EE0005574 的成果。该项目展示了五座轿车的轻量化潜力，同时保持车辆性能和乘员安全。制造了原型车并进行了有限的整车测试。 Mach-I车辆设计采用商用材料和生产工艺，实现了整车减重364公斤（23.5%），从而能够应用1.0升三缸发动机，从而带来显着的环境效益和燃油减少。2020年CAFE（企业平均燃油经济性）标准等法规要求、不断增长的公众需求以及上涨的燃油价格正在推动全球汽车制造商通过在新设计的车辆结构中采用轻质材料来提高燃油经济性。本文旨在传达生命周期评估 (LCA) 研究的结果，该研究将新型多材料轻量化 (MMLV) Mach-I (1.0l I3) 车辆设计的轻量化汽车零部件与基线 2013 款福特 Fusion (1.6l I4) 的传统汽车零部件进行比较，这两种内燃机车辆（汽油燃料）均在北美制造并行驶了 250,000 公里 [1]。总体质量减轻了 364 公斤（23%），从而实现了发动机尺寸的缩小，从而使整个生命周期质量引起的燃油节省了 3,642 升（或 962 加仑），预计联合循环燃油经济性为 34 英里/加仑（6.9 升/100 公里），而 2013 款福特 Fusion 为 28 英里/加仑（8.4 升/100 公里）。 Mach-I 设计车辆包括可商用的材料和技术。这项生命周期评价研究评估了汽车零部件从摇篮到坟墓的整个生命周期对环境的潜在影响，重点关注设计方案之间的重量差异。主要相关方包括美国能源部 (DOE)、安大略省、福特汽车公司和麦格纳国际公司。汽车零部件的LCA按照国际标准化组织（ISO）标准14040/44进行，并遵循CSA集团2014年汽车零部件LCA指南文件中提供的具体规则和指南[2,3,4]。
The Multi Material Lightweight Vehicle (MMLV) developed by Magna International and Ford Motor Company is a result of a US Department of Energy project DE-EE0005574. The project demonstrates the lightweighting potential of a five passenger sedan, while maintaining vehicle performance and occupant safety. Prototype vehicles were manufactured and limited full vehicle testing was conducted. The Mach-I vehicle design, comprised of commercially available materials and production processes, achieved a 364kg (23.5%) full vehicle mass reduction, enabling the application of a 1.0-liter three-cylinder engine resulting in a significant environmental benefit and fuel reduction.The Regulation requirements such as the 2020 CAFE (Corporate Average Fuel Economy) standard, growing public demand, and increased fuel prices are pushing auto manufacturers worldwide to increase fuel economy through incorporation of lightweight materials in newly-designed vehicle structures. This paper is aimed at communicating the results of a life cycle assessment (LCA) study which compares the lightweight auto parts of the new multi material lightweight (MMLV) Mach-I (1.0l I3) vehicle design to the conventional auto parts of the baseline 2013 Ford Fusion (1.6l I4), both internal combustion engine vehicles (gasoline fuelled), built and driven for 250,000 km in North America [1].The new Mach-I design has achieved an overall 364 kg (23%) mass reduction enabling engine downsizing, which resulted in a total life cycle mass-induced fuel savings of 3,642 liters (or 962 gallons) and a projected combined cycle fuel economy of 34 mpg (6.9 l/100 km), as compared to 28 mpg (8.4 l/100 km) for the 2013 Ford Fusion. The Mach-I design vehicle includes materials and technologies which are commercially available. This LCA study assesses the potential environmental impacts of the auto parts throughout their cradle-to-grave life cycle, with a focus on weight differences between design options. Primary interested parties are the US Department of Energy (DOE), Province of Ontario, Ford Motor Company and Magna International. LCA of the auto parts is conducted in accordance with International Organization for Standardization (ISO) standards 14040/44 and follow the specific rules and guidance provided in the CSA Group 2014 LCA Guidance document for auto parts [2,3,4].
