In February, Ford launched its own study on emission testing practices at the request of employees who noticed discrepancies in results. Whistleblowers believe that Ford may have miscalculated "road load" or factors affecting a car while on the road. It includes aerodynamic drag and tire resistance. A laboratory test that does not accurately account for the forces that a vehicle will be subjected to along the way can lead to better fuel economy projections and therefore suggests that cars emit less pollution than it actually does.
In addition to the internal investigation, fm has also flagged the environmental protection agency and works with california air resource board to help solve the problems. The proactive steps seem to jive with the fact that Ford does not intentionally attempt to make skirts, but justified errors in calculating its numbers.
Ford is not the only company facing a study on emissions at the moment. Daimler, the parent company of Mercedez-Benz and Fiat Chrysler are also dealing with criminal probes, though both companies accused of using defeat units and software to make cars seem cleaner than they actually do.
