Summary: Cars have been getting more fuel-efficient since 1973. From 1975 through the mid 1980s, this could be measured in higher miles per gallon. Since then, miles per gallon have remained the same but cars have gotten heavier and more powerful. The paper concludes that technological innovations have continued during both periods.
Quote: ”The rapid rise in fuel economy in the late 1970s was due to a mix of efficiency improvements and downgrading of utility in the form of reduced size, power, and eliminate of accessories and amenities (such as air conditioning). In constrast, since the mid-1980s, fuel economy has remained constant while the benefits of technological innovation were used to satisfy private desires (more power, size, and amenities).”
