    The most efficient pickup drivetrain once available in the U.S. should be back shortly!

    Following up on the RAM 1500 and Jeep Grand Cherokee EcoDiesel Emissions Issues story from January of this year, earlier today FCA stated that it has formally filed an application for diesel vehicle emissions certification with the EPA and the California Air Resources Board (CARB) for its 2017 model-year MY Jeep Grand Cherokee and Ram 1500 turbo diesel vehicles. The EcoDiesel will include updated emissions software calibrations to meet every last line of code in order to satisfy the U.S. EPA.

    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. With the permission of EPA and CARB, FCA US intends to install the same modified emissions software in 2014-2016 MY Jeep Grand Cherokee and Ram 1500 diesel vehicles. FCA US believes this will address the agencies’ concerns regarding the emissions software calibrations in those vehicles.

    FCA US also believes that these actions 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.

    FCA US expects that following EPA and CARB approval, owners of the 2014-2016 MY vehicles will be able to receive the software updates at their dealerships. FCA expects that the installation of these updated software calibrations will improve the 2014-2016 MY vehicles’ emissions performance and does not anticipate any impact on performance or fuel efficiency.

    Hi All:

    Not so fast. :(

    In 2016, Carder, Marc Besch, research assistant professor of mechanical and aerospace engineering in the Statler College of Engineering and Mineral Resources, Sri Hari Chalagalla, an engineer at CAFEE, and a team of engineers and technicians tested two Jeep Grand Cherokees and three Dodge Ram 1500 pickup trucks equipped with the 3.0L EcoDiesel.

    The team conducted on-road emissions testing with a scaled-down versions of traditional laboratory equipment called a portable emissions measurement system, or PEMS.

    This “mobile lab” fits in the back of the vehicle and samples and analyzes its exhaust while it is being driven on the road, allowing researchers to study the performance of the vehicle’s cleaning technologies in real-world driving conditions.

    CAFEE’s testing covered a variety of road and ambient conditions, traffic patterns and terrain over two routes – an urban and a highway route – in the Morgantown, West Virginia, area.

    Additionally, CAFEE engineers tested the vehicles in their lab. There, a vehicle is placed on a light-duty chassis dynamometer, which functions as a large treadmill.

    The instrument allows the vehicle to be driven through a test that closely simulates the route that was driven on the road. The study used the same mobile lab equipment used on the road to analyze the vehicles’ exhaust in the laboratory.

    The testing showed that compared to in-laboratory tests, route averages of NOx emissions exceeded government standards by a factor of 3 to 20 during on-road driving.

    Carder:
    Carder said that data from CAFEE research will be used by the center to help refine existing vehicle technologies and define technology advancements for the future. Additionally, CAFEE uses data from its research and other independent research organizations, to identify possible gaps between regulatory certification and compliance standards and real-world performance.

    Carder added that Clean diesel is not a myth!
    FCA Statement

    FCA has been made aware of on-road emissions testing conducted on two of the Company’s diesel-powered vehicles by West Virginia University’s Center for Alternative Fuels Engines and Emissions (CAFEE). Based upon court filings and discussions with CAFEE, this testing appears to have been commissioned by a plaintiffs’ law firm for purposes of litigation.

    FCA US has asked CAFEE to discuss its testing methodology and share the resulting data for the Company’s understanding, and to determine which on-road test results could conceivably be compared with results from U.S. Environmental Protection Agency (EPA) laboratory procedures. CAFEE has been unwilling to discuss the report.

    The CAFEE report implies it would be appropriate to compare its on-road test results with those of one of five required EPA test procedures – each of which is conducted off-road, under laboratory conditions. However, CAFEE’s reported on-road results fail to consider that its tests were conducted:
    • At average speeds more than 50% greater than those in the EPA test procedure
    • With 600-700 lbs. more payload than is used in the EPA test procedure
    • Under road conditions (e.g., grades) that are not representative of those in the EPA test procedure
    Each of the above may increase emissions readings, therefore rendering invalid a comparison of on-road and off-road test results. Further, the aggregation of these variations makes any comparison misleading.

    Despite the report, there is no regulatory protocol for conducting on-road emissions testing. The report also indicates that the vehicles were modified by CAFEE prior to testing ostensibly in an effort to replicate a prior recall.

    FCA US has formally filed an application for diesel vehicle emissions certification with the EPA and the California Air Resources Board (CARB) for its 2017 model year (MY) Jeep Grand Cherokee and Ram 1500 diesel vehicles, the latest model year of the same vehicles apparently tested by CAFEE. FCA US has updated the emissions software calibrations in this MY 2017 certification proposal.

    The updated calibrations are 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. FCA US continues to discuss improved software calibrations with the agencies. Subject to the permission of EPA and CARB, FCA US intends to install the same modified emissions software in 2014-2016 MY Jeep Grand Cherokee and Ram 1500 diesel vehicles. FCA US believes this will address the agencies’ concerns regarding the emissions software calibrations in those vehicles.
