Estimate of Changes to Fuel Economy Label Values Resulting from the Proposed Mid-Year Label Updating

摘要

The Environmental Protection Agency (EPA) is proposing several changes to the current fuel economy program which will increase the usefulness and representativeness of the fuel economy values to consumers. One of these proposals is to have the label values updated at least once per model year, at about mid-year. The label updating would involve recalculating the label values using revised sales projections and including test data obtained since the initial label calculation. This report estimates the maximum number of label values that would likely change by mid-year and magnitude these changes.
