Fiat Chrysler has filed a formal application with the U.S. Environmental Protection Agency (EPA) and the
California Air Resources Board (CARB) to have its 3.0-liter EcoDiesel V6 engine certified for the 2017 model year.
FCA says the filing “is the result of many months of close collaboration between FCA US and EPA and CARB, including extensive testing of the vehicles, to clarify issues related to the Company’s emissions control technology.”
The EPA alleges that FCA used a ‘cheat device’ on its 3.0-liter EcoDiesel V6 engine and failed to disclose its presence to regulators. It’s believed the device would alter the way the engine performed under certain driving scenarios and would revert to a less emissions-friendly mode when more performance was needed. The engine is found in 2014-2017 model year Jeep Grand Cherokee and Ram 1500 vehicles.
FCA seems to have developed a software fix for the engine that ensures the engine is within emissions compliance 100% of the time. The automaker says the software fix should “help facilitate a prompt resolution to ongoing discussions with the Environment and Natural Resources Division of the U.S. Department of Justice and other governmental agencies.” The software fix will also be made available for owners of affected 2014-2016 model year vehicles.
We’ll update this story as more information on the certification of the EcoDiesel engine surfaces.
