Ford Motor Co. lowered fuel-economy estimates on some of its cars for the second time in less than a year, citing a computer-modeling error, and promised to compensate more than 200,000 customers.

Six models are affected, including the C-Max Hybrid, which is now rated at 40 miles per gallon overall, the Dearborn, Michigan-based company said in a statement Thursday. That’s down from an estimate revised lower last year to 43 mpg from 47 mpg.

Payments to customers will be as high as $1,050 to owners of the Lincoln MKZ Hybrid and as low as $200 to owners of the Fiesta with a 1-liter engine, the company said. Other models include the Fusion Hybrid, the C-Max Energi and the Fusion Energi.

“This is our error,” Raj Nair, Ford’s group vice president for global product development, said in a conference call. “When we see an issue, we address it.”
