Super Duty or Super Dirty?
The outlet claims a proposed class action lawsuit against the automaker states that about 500,000 heavy-duty pickup trucks cheated emissions testing.
The law firm representing the owners, Hagens Berman, has launched lawsuits in the previous year against General Motors and Fiat Chrysler Automobiles as well as engine maker Cummins, making similar allegations.
The lawsuit alleges that Ford worked with supplier Robert Bosch GmbH to hide the affected trucks' inefficiencies for the sake of offering greater performance. In 2015, Volkswagen got in deep trouble when it admitted many of its diesel cars in America had "defeat devices", which effectively allowed the vehicles to blunt their emissions to pass federal tests.

He demanded the border wall in exchange for protection against the deportations of young immigrants who were brought into the U.S.as children, who also known as Dreamers.
Ford said in a statement that all of its vehicles comply with all US Environmental Protection Agency and California Air Resources Board emissions regulations.
The lawsuit could cast some doubt on Ford's claims.
"It is not plausible, given [Ford's] "groundbreaking" testing, that Ford and Bosch did not know that emissions controls do not work when the vehicle is operating in normal stop-and-go conditions, running under heavier loads, and going up modest to steep grades", Berman says.
"Ford vehicles do not have defeat devices", the company said. The company called the suit claims "baseless".
"Bosch takes the allegations of manipulation of the diesel software very seriously", Bosch spokesman Rene Ziegler said. It is a well-known fact that these allegations remain the subject of investigations and civil litigation involving Bosch.
