摘要：	This report summarizes key fuel economy and technology usage trends related to model year 1975 through 2001 light vehicles sold in the United States. Light vehicles are those vehicles that EPA and the U.S. Department of Transportation (DOT) classify as cars or light-duty trucks (sport utility vehicles, vans, and pickup trucks with less than 8,500 pounds gross vehicle weight ratings). Average new light vehicle fuel economy continues to decline. Since peaking at 22.1 mpg in 1987 and 1988, average light vehicle fuel economy has declined nearly eight percent to 20.4 mpg, and for 2001 is lower than it has been at any time since 1980. The primary reasons for this decline are the increasing market share of less efficient light trucks, increased vehicle weight and increased vehicle performance. The fuel economy values in this report are based on laboratory data, but for most tables and analyses in the report have been adjusted downward, by about 15 percent, so that this data is equivalent to the real world estimates used on new vehicle labels, in the EPA/DOE Fuel Economy Guide and in EPA’s Green Vehicle Guide. These adjusted fuel economy values, therefore, are significantly lower than those used by the DOT for compliance with fuel economy standards. In addition, the values in this report exclude Corporate Average Fuel Economy (CAFE) credits for alternative fuel capability and corrections for test procedure adjustments, that are included in the fuel economy data reported by DOT.
