The VW Group’s proposed fix for its 2-liter diesel may have just been shot down, but Porsche is confident its solution for the emissions cheating 3-liter diesel V6 will be approved by local authorities.
Approximately 13,000 units of the Porsche Cayenne in the United States are installed with a 3.0-liter V6 from Volkswagen also found guilty of cheating emissions tests. That engine was originally designed by Audi and is also used in a number of Audi models produced since 2009.
To allow this engine to meet emissions standards, Porsche plans on installing new catalytic converters while also giving 2013, 2014, 2015 and 2016 Cayenne models software updates.
The plan, drew up by Audi, will be presented to the Environmental Protection Agency and the California Air Resources Board in early February. It isn’t yet known if Audi intends on utilizing the same fixes for its affected 3.0-liter diesel V6 models in the U.S.
During the Detroit Auto Show, Porsche chief executive Oliver Blume told Reuters :
“We had a very positive and constructive discussion [when presenting the plans]. The technical aspects have all been submitted, we will wait whether there will still be proposals for corrections by the Americans. Everything we can do for this particular engine has been done for now and we are now awaiting feedback.”
Of the 13,000 affected Cayenne models, Porsche believes that less than half will require a new catalytic converter and will simply need software updates.
