The outlet claims a proposed class action lawsuit against the automaker states that about 500,000 heavy-duty pickup trucks cheated emissions testing.
Law firm Hagens Berman said in a release that it believes Ford and German supplier Bosch installed "emissions-cheating software devices" in the MI automaker's 2011-2017 Ford F-250 and F-350 Super Duty pickup trucks. The global retaliation for the use of so-called "cheat devices" started with Volkswagen in 2015, and since then, at least another four automakers - including Ford - have been accused in the USA of using similar tricks to pass emissions testing, while emitting pollutants in quantities that are many times what is legally allowed.
For those that tow their show or race cars the Ford F-Series Super Duty with Power Stroke diesel has been the go to hauler for decades. Now Ford is upping the ante on diesel power with a new F-150 Power Stroke diesel that could offer as much as 30 mpg on the highway, and provide up to 11,400 pounds of towing capacity.
The suit filed in MI also named German auto supplier Bosch as a defendant.
"The vehicle's own on-board diagnostic software indicates emission control system to be operating as Ford intended, even though its real world performance grossly exceeds the standard", attorney Steve Berman, a managing partner at Hagens Berman, said in the complaint. Bosch has also been named as a defendant.
Ford fans have been asking for a fuel efficient diesel offering in the smaller, lighter, F-150 truck for a while now and Ford will now offer just such a truck in the 2018 model year.
Diesel engines, while more fuel-efficient, produce greater volumes of nitrogen oxide pollutants.
Bosch is accused of developing software that enabled Ford to adjust such things as fuel levels and exhaust gas recirculation and air pressure rates while being tested for emissions by regulators including the Environmental Protection Agency and California Air Resources Board.
Europe is a leading region for Ford global diesel engine development, with experts based in Dagenham as well as the Dunton Technical Centre, U.K.; Merkenich Technical Centre, Germany; and the Ford European Research and Innovation Centre, Germany.
Hagens Berman is no stranger to pursuing automakers over diesel emissions.
GM has denied allegations of wrongdoing in lawsuits against the company.
