Mitsubishi is trying to assure U.S. regulators that it hasn’t been cheating on emissions tests. It won’t be an easy road after admitting it’s been conducting improper tests that don’t meet Japanese regulations for the past 25 years.
This week, the U.S. EPA directed Mitsubishi to provide more details and conduct new emissions tests on U.S. vehicles. It’s a particularly sensitive issue for the agency in the wake of the ongoing VW diesel scandal.
Mitsubishi addressed U.S. concerns in a statement released late Wednesday. The automaker says it’s conducted an audit going back several model years and that it’s found no issues in U.S. vehicles model years 2013-2017.
“To confirm that U.S. market vehicles are not affected by this issue, Mitsubishi Motors R&D America, Inc., working together with Mitsubishi Motors Corporation, proactively conducted an internal audit of U.S. market vehicles going back several model years to check previously submitted data to the EPA,” Mitsubishi said in a statement. “After a thorough review of all 2013MY – 2017MY vehicles sold in the United States, we have determined that none of these vehicles are affected. Our findings confirm that fuel economy testing data for these U.S. market vehicles is accurate and complies with established EPA procedures.”
The automaker also says the Japan emissions tests are entirely different and have no bearing on U.S. test results.
“An entirely different system is used for the United States market to determine what the EPA calls Road Load Coefficient, strictly adhering to EPA procedures,” Mitsubishi said in a statement. “The data generated is then independently verified for its accuracy before being submitted to the EPA for their fuel economy testing. MMNA has shared this information with EPA, California Air Resources Board and DOT.”
Mitsubishi says an external team is investigating its fuel economy testing practices. It plans to make the results of the completed investigation public. Mitsubishi says it is also working closely with the Japanese Government to discuss potential resolutions in its home market.
