Ford is lowering the fuel economy rating for six of its vehicles, including most 2014 Ford Fiestas, according to a company press release issued on June 12.

The Detroit automaker apologized to its customers for the issue, and said it will make "goodwill payments" to owners of affected vehicles for the difference between the previous and the revised ratings.

Approximately 200,000 vehicles are affected by the announcement.

Compensation payments will range from $125 for lease customers of the 2014 Ford Fiesta 1.0 GTDI with a manual transmission to $1,050 for purchase customers of the 2013-'14 Lincoln MKZ hybrid, according to the automaker.

The EPA said in a statement that the automaker is required to correct fuel economy labels on all affected vehicles within 15 days

"Most labels will change between 1 and 5 mpg," the EPA said. "The largest change is for the Lincoln MKZ hybrid, whose combined city and highway fuel economy value has been reduced by 7 mpg."

Other affected vehicles include: the 2013-'14 Ford Fusion Hybrid and Energi models, 2013-'14 Ford C-Max Hybrid and Energi models and the 2013-'14 Lincoln MKZ Hybrid.

The 2014 Lincoln MKZ Hybrid returns 38 mpg in city driving and 37 mpg on the highway, according to the corrected figures on the EPA site.

Ford originally claimed that the MKZ returned 45 mpg in city driving and 45 mpg on the highway.

"Ford has agreed to implement enhanced validation tests for future vehicles under EPA oversight," the EPA said.

No other label adjustments are planned.

New fuel economy labels will reach dealerships in approximately five days and dealers can continue selling the vehicles until the labels are received, according to the automaker.
