从美国环境保护署(EPA)进行的排放测试中获得的燃油经济性数据被用来显示从1957年车型年到现在的乘用车燃油经济性趋势。本文将1975车型年添加到历史趋势中，并集中于1975和1974车型之间的比较。在假设不发生车型组合变化的情况下，机队燃油经济性的净变化估计为+13.8%，与1975年的车型相比。通用汽车公司是车队平均改善的主要原因。
The fuel economy data obtained from the emission tests run by the U.S. Environmental Protection Agency (EPA) have been used to show passenger car fuel economy trends from model year 1957 to present. This paper adds the 1975 model year to the historical trend and concentrates on comparisons between the 1975 to 1974 models. The net change in fuel economy for the fleet has been estimated at plus 13.8% comparing the 1975 models to the 1974 models assuming no model mix change occurs. General Motors is responsible for the majority of the fleet average improvement.
