Abstract
Since 1978 Ford Motor Company has been surveying the fuel economy of employes who lease new light duty vehicles from the Company. Winter and summer survey data for the three years are analyzed and compared. Car results show a significant and steady increase in average on-road fuel economy over the three year period. The percent differential between EPA measured and actual on-road fuel economy has lessened substantially since 1978. Furthermore, the percent difference between EPA and on-road is essentially constant over the range of EPA values for each of the three years. Limited fuel economy results for 1980 trucks are also discussed.
