"Ford Motor Company said on Thursday that it was investigating how it tested the emissions and fuel efficiency of its vehicles after employees reported possible flaws with the company’s computer models.

The company said it had notified the Environmental Protection Agency about the issue and had hired a law firm, Sidley Austin, to investigate specifications it used in the testing.

Kim Pittel, group vice president for sustainability, environment and safety engineering at Ford, said that the investigation had not indicated, so far, that the company reported incorrect data to consumers or regulators."
