The U.S. Environmental Protection Agency (EPA) disclosed that Ford Motor Company is revising the miles per gallon (mpg) estimates for six vehicle models to correct errors found in an internal Ford audit. Ford is required to correct fuel economy labels on affected vehicles immediately.
EPA oversaw Ford’s re-testing program and conducted independent tests to confirm the corrected results as soon as it was notified by Ford of the potential errors. Ford has agreed to implement enhanced validation tests for future vehicles under EPA oversight.
“This issue highlights the need for continued strong oversight of the fuel economy labeling program,” said Chris Grundler, director of EPA’s Office of Transportation and Air Quality. “Consumers need to trust that fuel economy window stickers are giving consumers reliable and fair estimates of real world fuel economy.”
Cars currently in dealer lots will be re-labeled with new window stickers reflecting the corrected mileage estimates. Ford will re-label four versions of the Ford Fiesta, the Hybrid and Energi versions of the Ford Fusion, the C-Max Hybrid and Energi, and the Lincoln MKZ Hybrid. Most labels will change between one to five mpg. The largest change is for the Lincoln MKZ hybrid whose combined city and highway fuel economy value has been reduced by 7 mpg. EPA and DOE have updated their joint fuel economy site, www.fueleconomy.gov, to reflect the corrected numbers.
EPA’s National Vehicle and Fuel Emissions Laboratory in Ann Arbor, Michigan, conducts fuel economy testing on a number of vehicles each year to ensure that their performance matches the mileage and emissions data submitted to EPA by automakers. These “spot-checks” are part of the oversight program that helps verify that vehicles on the road meet tailpipe emission standards and that all carmakers follow the same procedures for calculating mileage estimates.
