Ford worked with German automotive supplier Robert Bosch to mask the vehicles' inefficiencies in order to maintain overall performance, according to the complaint filed Wednesday in Detroit federal court.
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 Super Duty trucks - dubbed "Super Dirty" by the lawyer behind the class-action suit - use a "reverse" exhaust layout that puts the catalytic reduction before the particulate filter (DPF).

From power ratings to price, Ford is being very aggressive with the diesel-powered F-150 pickup due out later this year. It's expected to return up to 30 mpg on the EPA's highway cycle.
That's right, Ford has never offered a diesel in the F-150 class.
Hagens Berman hit Ford and Bosch with a total 58 counts of violations of state consumer laws, false advertising laws, deceptive trade laws as well as violation of the Racketeer Influenced and Corrupt Organizations Act (RICO).
"We know that competing diesels with electric cooling fans have to dial back on power under extreme heat and altitude, so we decided on a viscous-controlled mechanical fan that has the capacity to move much more air across the radiator and intercooler in extreme conditions", said David Ives, Ford diesel engine technical specialist. "The more you tow and the longer you haul, the more you'll appreciate its class-leading towing and payload capacity and how efficient it is at the pump". The campaign evolved over the years, and as recently as 2017, Ford's vehicle brochures boasted of reduced nitrogen oxide levels "in the real world" and "unsurpassed diesel fuel economy".More news: Defense lifts Jaguars past Bills
Felipe said that the diesel fuel tank will be 26 gallons, which is similar to the standard tank on Super Crew pickups, but smaller than the extended-range, 36-gallon tank offered on gas-powered models.
Hagens Berman is no stranger to pursuing automakers over diesel emissions.
