- Ford says errors in its own procedures caused it to overstate EPA-estimated mileage for some of its most efficient models.
- The resulting rollback caused the American Council for an Energy- Efficient Economy to re-rank those models, costing Ford its high-placed "greenest" rankings for 2013.
- The ACEEE says Ford's "oops" didn't affect its 2014 standings in the group's "Greener Cars" rating.
WASHINGTON — A week after Ford Motor Co. 'fessed up to overstating the EPA-estimated fuel economy numbers for six of its most efficient models, several of the company's cars have been downgraded in the 2013 "greener cars" rankings published by the American Council for an Energy-Efficient Economy.
With their "green" scores reduced, the 2013 Ford Fusion Hybrid and C-Max hybrid drop off the ACEE's list of the dozen most environmentally friendly cars for the 2013 model year. The two were tied for 12th place in the listing with 51 points each out of a theoretically perfect score of 100.
Because of Ford's fuel economy ratings cut, the Fusion Hybrid's green score dropped to 49 points and the C-Max hybrid's score was cut to 48 points.
They have been replaced on the 2013 list by a new 12th-place finisher, Acura's ILX Hybrid.
The environmental lobbying group, which has published its greenest cars list for 17 years, said Ford's fuel economy foul-up didn't affect the ACEEE's 2014 rankings. There were no domestic models in the top finishers this year.
Ford has said inflated fuel economy ratings were the result of internal testing errors that have now been corrected.
Edmunds says: This is the third ratings "goof" in two years, further weakening consumers' trust in the EPA fuel efficiency estimates. Perhaps it is time the EPA re-examines the rules governing how automakers do their own testing.
