Over the past decade, governments in North and South America, Europe and Asia have enacted stricter fuel economy and emissions requirements. To comply with these regulations, the automotive industry has focused research and development efforts on improving the efficiency of the internal combustion engine, implementing new powertrain technologies, lowering the costs of vehicle electrification, and reducing vehicle mass—also known as light weighting. Mass reduction is complementary to all other efficiency efforts; simply stated, lower weights require less energy to move. Estimates of the efficiency gains from mass reduction vary, but frequently state that a 10% reduction in vehicle mass, when coupled with powertrain downsizing, improves the fuel economy of a gasoline vehicle by 6–7 percent (Ricardo-AEA, 2015).
