AN ANALYSIS OF FORD LEASE FLEET FUEL ECONOMY DATA THROUGH 1984 MODELS

Since the 1978 model year, Ford Motor Company (Ford) has been collecting and analyzing on-road fuel economy data for Ford vehicles leased by Company employees. Based on these data, on-road mpg for 1983-84 model passenger cars is approximately 40% better than for 1978 models. Also, the percent by which average on-road results are below EPA-approved CAFE values (i.e., mean "% Offset") is 15% for recent models versus 20% for 1978 models. Since 1981, on-road results have been compared to label (i.e., "City") values approved by EPA to determine the percentage of drivers who meet or exceed the label mpg. For 1983 and 1984 models, on-road comparisons also are made to mpg values adjusted downward consistent with EPA's fuel economy labeling rules for 1985 models. Comparisons to EPA-approved CAFE and label values, plus to adjusted label values, also are made based on specified driving patterns and for summer vs. winter surveys.
