Cummins Emissions Review Continuing

02 August 2019

In a recent conference call with analysts, Cummins officials were questioned about the company’s ongoing review of its emissions certifications processes for its 6.7 L engines used in 2019 Dodge Ram 2500 and 3500 pickup trucks. In late April, Cummins announced that it had commenced a review after discussions with the U.S. Environmental Protection Agency (EPA) and California Air Resources Board (CARB).

Cummins Chairman and CEO Tom Linebarger said that “our review continues, and we are proactively working closely with the EPA and CARB and other agencies to address their questions.’

Linebarger said that EPA and CARB “raised concerns that certain aspects of our emission systems may reduce the effectiveness of our emission control systems and did not fully comply with the requirements for certification. As a result, our internal review has been largely focused on the agency’s concerns.”

While that review is ongoing, Linebarger said “it’s too early to conclude on any changes that we will make to our processes and organization as a result of our internal review. It’s also too soon to know what the response of the regulators will be to our view, or to determine any potential financial consequences.

“Consistent with the values and the history of the company, which include a strong commitment to compliance, we’ll work with regulators and other agencies to address the issues identified in our internal review and develop future technologies that will advance our industry.”
Cummins turbodiesel engines have been an option on Dodge Ram pickups since 1989 and to date, the company has supplied well over two million engines for the vehicle.
