Ford investigating possible problems with gas mileage and emissions testing

Ford Motor Co said on Thursday it has hired outside experts to investigate its vehicle fuel economy and testing procedures after employees raised concerns, and did not know whether it would have to correct data provided to regulators or consumers.

The issues involving Ford’s testing processes do not involve the use of so-called defeat devices — hardware and software designed deliberately to deceive government emissions tests, Kimberly Pittel, Ford’s group vice president for sustainability, environment and safety engineering, told Reuters.

The automaker since last fall has been investigating concerns raised by employees that incorrect calculations were used to translate test results into the mileage and emissions data submitted to regulators, Pittel said.

Ford said it was evaluating changes to the process it uses to develop fuel economy and emissions figures, “including engineering, technical and governance components.”
