Vehicle Emissions are bad for the environment, and not to good for us humans either. That's why emission tests and regulations exist, to try and make cars not so bad for us. Not all automakers follow these rules, unfortunately.

An American law firm is accusing Ford Motor Company of rigging emissions tests on the F-250 and F-350 Super Duty trucks with the usage of emissions-cheating devices. A lawsuit against Ford was filed last Wednesday.

The lawsuit, filed by Hagens Berman, states that Ford had manipulated the emissions system in violation of federal requirements and that the trucks in question release twice the emissions as legally limited to with normal driving.

The lawsuit was filed in the U.S. District Court for the Eastern District of Michigan in which it names German auto supplier Robert Bosch GmbH as a defendant.

This wouldn't be the first time an automaker had been caught cheating on emissions tests. It's hard to imagine that someone would make a legal accusation like this without sufficient evidence, so odds aren't looking good for Ford right now.
