The Cost-Effectiveness of Fuel Economy Improvements in 1992 Honda Civic Hatchbacks
Since the early 1980s, both U.S. auto 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. The purpose of this project was to assess such assertions using a specific example. In a paper based on our research, we analyze fuel economy improvements in 1992 Honda Civic hatchbacks. The 1992 Hondas were virtually identical to the 1991 models in size, vehicle amenity, engine power, and performance, but offered substantially increased fuel economy and improved safety.
In our paper, we assess the cost of improving fuel economy using actual retail prices, after correcting for differences in cosmetic features. Our calculations show that the 1992 Civic DX was 56% more efficient than the 1991 model. This improved fuel economy was achieved at a cost of 77¢ per conserved gallon of gasoline - 30% less than the levelized gasoline price without externalities or taxes. In addition, a comparison of two other Civic models reveals that fuel economy was improved in the 1992 version at no additional cost. Virtually all of the efficiency increases described in our paper were achieved through measures that did not affect safety or vehicle size, such as engine modifications, transmission alterations, and drag reduction.
