Fiat Chrysler Automobiles (FCA) is back in the diesel game, following certification from the Environmental Protection Agency (EPA) and the Air Resources Board (CARB) in California.
The certification of conformity follows several months of investigation and collaboration concerning emissions technologies on previous diesel engined versions of the Ram 1500 pickup and Jeep Grand Cherokee sport utility vehicle, and means that FCA can again market the vehicles, equipped with a 3.0-litre turbodiesel V-6, for the 2017 model year.
The modifications include emissions software recalibration, but do not require any hardware changes. Testing indicates that there is no effect either on stated fuel economy figures or on performance.
There is also a chance that the changes could be applied to the models that in January of this year were slapped with the notice of violation — 2014-16 model year Grand Cherokees and Ram pickups
“The approvals announced today represent a significant step toward resolving the issues raised by EPA and ARB,” concluded Sergio Marchionne, Chief Executive Officer of FCA. “We appreciate the efforts of the agencies in working with us to achieve this milestone. We are anxious to build on this progress to make appropriate updates to the emissions control software in our earlier model-year vehicles.”
