Abstract:

Lightweighting in the automotive industry has been primarily motivated by fuel economy and greenhouse gas emission targets. The target greenhouse gas emissions and, therefore, the fuel economy for the average vehicle in both the United States and European Union are required to achieve significant annual improvements through 2026. Weight reduction, or lightweighting of an automobile, provides improvements not only in the fuel economy of engine-powered vehicles but also provides for improvements in the driving range of electric vehicles. As an industry example, the 2017 Chrysler Pacifica minivan utilizes a blend of high-strength steels, aluminum, and magnesium to reduce vehicle weight by over 100 kg, helping achieve a nearly 10% reduction in greenhouse gas emissions in a larger vehicle footprint with increasing industry safety demands [1].
