United States. Congress passes the Corporate Average Fuel Economy (CAFÉ) Act, which requires American automakers to produce vehicles that consume less gasoline. Gasoline fuel economy drops from 15 miles per gallon in 1975 to 25 miles per gallon in 1983, despite an average increase in engine size. The trend worsens further in the following decades, with a continued increase in engine size accompanied by a continued decrease in fuel consumption.
