GENERAL MOTORS ACCUSED * USA: To use illegal emissions software

* Michigan - GM sued by diesel truck owners over emissions

--- General Motors Co. was accused in a lawsuit by owners of diesel-powered trucks of using illegal emissions software that allowed the vehicles to bypass government emissions tests and pollute far beyond legal limits on the road... Owners of heavy-duty Chevrolet Silverado and GMC Sierra Duramax pickup trucks sued GM in a Detroit federal court on Thursday, accusing the auto maker of using so-called defeat devices that deceived government regulators. The devices allowed the vehicles to appear cleaner during government tests, and then emit nitrogen oxides two to five times above allowable limits in normal driving conditions, according to the lawsuit... The suit targets more than 705,000 vehicles currently estimated to be on the road, with model years between 2011 and 2016... The suit says GM promised its diesel-engine technology would turn heavy fuel into a "fine mist" and deliver low emissions that were a "whopping reduction" from the previous model. Instead, GM used three defeat devices that turn down emissions controls when the vehicle isn't being tested, the lawsuit alleges... GM's heavy-duty diesel trucks are among the company's most-profitable vehicles, typically selling for more than $60,000. They represent about 12% of GM's overall pickup-truck sales, according to RBC Capital Markets. The pickup business accounts for more than half GM's bottom line globally, according to analysts... GM introduced a new Duramax engine on the heavy-duty Silverado and Sierra for the 2017 model...
