Ford announced Thursday the motor company is hiring an outside firm to conduct an investigation into its internal process for complying with U.S. fuel economy and emissions standards.
In September, some of the company's employees raised concerns about the analytical modeling that is part of Ford's U.S. fuel economy and emissions compliance process.
In response to the concerns, the company hired independent industry technical experts to investigate the "vehicle road load" specifications used in its testing.
Ford shared their concerns with Environmental Protection Agency and California Air Resources Board officials and it was concluded that the investigation does not involve the use of defeat devices in Ford's products.
"Road load is a vehicle-specific resistance level used in vehicle dynamometer testing, including for fuel economy ratings and emissions certifications. Road load is established through engineering models that are validated through vehicle testing, including physical track tests referred to as coastdown testing," Kim Pittle, Sustainability, Environment & Safety Engineering group vice president said in a statement.
