IMPROVING FUEL ECONOMY: A CASE STUDY OF THE 1992 HONDA CIVIC HATCHBACKS

Since the early 1980s, U.S. automobile makers and policy makers have resisted policies to increase automobile fuel economy, arguing in part that such increases were neither technically feasible nor economically justified. Such assertions for the 1992 Honda Civic hatchbacks are analyzed. With the 1992 Honda Civic model line, an automobile maker has, for the first time, produced cars that are virtually identical to the previous year's models in size, vehicle amenity, engine power, and performance, but that offer substantially increased fuel economy and improved safety. The cost of improving fuel economy is assessed using actual retail prices, after correcting for differences in cosmetic features. Calculations indicate that the efficiency of the 1991 Civic DX was improved by 56% from 1991 to 1992 at a cost per conserved liter of gasoline that is $.20/L ($0.77/gal), or 30% less than the levelized gasoline price without externalities or taxes. In addition, a comparison of two other Civic models indicates that fuel economy was improved in the 1992 versions at no additional cost. Virtually all of the efficiency increases described here were achieved through measures that do not affect safety or vehicle size, such as engine modifications, transmission alterations, and drag reduction.
