Recent work performed to modify and update the Highway Fuel Consumption (HFC) model is described. Recent analyses and additions which have been made to improve the usefulness of the HFC model as a flexible tool for energy conservation policy and program evaluation are documented. Actual on-road fuel economy estimates for pre-MY1975 passenger cars are developed from household fuel purchase and travel surveys. The analysis assesses the changes in the output of the HFC model which result from the incorporation of these data into the model framework. The influence of trends in odometer and vehicle levels on in-use fuel economy is examined. A vintage-related index of the sensitivity of in-use fuel economy to vehicle odometer levels and changes in average daily miles of travel is constructed and incorporated into the HFC model. The feasibility of incorporating an exogenous forecast of total highway travel into the HFC model for the purpose of adopting the fuel consumption output to correspond with econometrically-based projections of vehicle use is examined. A brief literature survey of available econometric forecasts of total highway VMT is performed; and a methodology for including these forecasts within the HFC model structure is developed and tested.
