Abstract
The pre-1975 EPA fuel economy data base has been expanded to over 6,600 cars, and these data on older cars have been adjusted for odometer mileage effects on fuel economy. The data base for model year 1975-1977 certification cars is also updated, reflecting actual sales figures. The resulting trend analyses are thus (for the first time) consistent from year to year with regard to the representation of actual sales weighted new-car fleet fuel economy.
Data on the 1979 fleet is presented in detail, and compared with that of the 1978 fleet, on the basis of projected sales for those two years.
Comparisons with pre-emission control MPG, which serve as measures of technological change accompanying increasingly stringent emission standards, are accordingly revised from previous publications (1)* on this subject.
Passenger car size classes and interior volumes are treated in the trend sense, and also in a study of interactions between vehicle technology, fleet physical attributes, and post-1979 fuel economy standards.
