Repeated complaints about the fuel economy to the EPA on the Fusion Energi, C-Max Energi, along with the standard hybrid versions of both, as well as the Lincoln MKZ have prompted Ford to finally restate efficiency figures for both 2013 and 2014.
In attention to correcting the MPG numbers, which in some cases were off by as much as 7 miles per gallon, Ford is offering "goodwill payments to owners of the approximately 200,000 affected U.S. vehicles for the difference between the previous and revised ratings."
The amount of the payments vary from $200 to $1,050 , but in the case of the C-Max Energi a $775 rebate is being offered ($475 if leased) and $850 for the Fusion Energi ($525 if leased). Full 'checks in the mail' chart by vehicle listing can be found below.
- For the C-Max Energi, MPG is lowered to 38 from 43, while MPGe drops from 100 to 88, all electric range moves from 21 to 19 miles
- For the Fusion Energi, MPG is lowered to 38 from 43, while MPGe drops from 100 to 88, all electric range moves from 21 to 19 miles
Three Popular Fords And The C-Max Got A MPG Haircut On Thursday
Ford puts the blame for the errors on something called TRLHP or Total Road Load Horsepower, which they define as a "specific resistance level used in vehicle dynamometer testing that determines fuel economy ratings."
The Ford Fusion Energi Loses 5 MPG, And Has MPGe Rating Cut From 100 to 88
TRLHP is established through engineering models that are validated through vehicle testing, including physical track tests referred to as coastdown testing.
Use of these engineering models is a common industry practice, consistent with EPA regulations. These models normally are more reliable and consistent than physical vehicle tests, which can exhibit variability.
As an ongoing practice, Ford conducts tests on production vehicles to validate its engineering models. Based on coastdown testing of the Fusion Hybrid, the company found the TRLHP did not match the values used for the dynamometer testing.
Upon further testing, Ford also discovered an error specific to how we correlate wind tunnel results into the TRLHP model. Ford’s error was the result of a recent process change, which the company has since corrected.
Ford has now validated through physical vehicle testing the TRLHP for the vehicles affected by this error and also has instituted enhanced validation tests for future vehicles to prevent reoccurrence of this error.
Naturally CEO and President Alan Mulally made a statement:
“Ford is absolutely committed to delivering top fuel economy and accurate information. We apologize to our customers and will provide goodwill payments to affected owners. We also are taking steps to improve our processes and prevent issues like this from happening again.”

*Bolded figures in the above chart represent the values used to determine the customer goodwill payment.
** Combined numbers only. Revised EPA-estimated ratings: 40 city, 36 highway MPG; 95 city, 81 highway MPGe. Charge depleting range is 20 mi. Previous EPA-estimated ratings: 44 city, 41 highway MPG; 108 city, 92 hwy MPGe. Previous charge depleting range was 21.
+MPGe is the EPA equivalent measure of gasoline fuel efficiency for electric mode operation.
