This report provides data on the fuel economy, carbon dioxide (CO2) emissions, and technology trends of new light-duty vehicles (cars, minivans, sport utility vehicles, and pickup trucks) for model years 1975 through 2011 in the United States. For model year 2010, the last year for which the U.S. Environmental Protection Agency (EPA) has final data, EPA projects average real-world CO2 emissions to be 394 grams per mile and fuel economy to be 22.6 miles per gallon (the fuel economy values in this report are those that EPA provides to consumers, and are lower than the fuel economy values used for compliance with Corporate Average Fuel Economy (CAFE) standards. CO2 emissions and fuel economy are at their most favorable levels since the EPA database began in 1975, and are slightly better than the previous best year of 2009.
