Should VW's dirty-diesel-debacle concern GM diesel owners?

    Over the weekend the big news in the automotive world was that the EPA has accused Volkswagen of purposely rigging its diesels to cheat emissions testing. According to an EPA document, VW has admitted to the cheating. The upshot is that VW diesels from 2009 through 2015 have been operating at 10 to 40 times the legal limit of NOx (oxides of nitrogen). Whether you care about the environmental impacts of emissions or not, you should care about automakers cheating on emissions equipment. Cars and trucks that don't meet emissions standards and have not had recalls completed can be precluded from being registered in California and the 10 other states that follow its guidelines. Consumer Reports has issued a statement saying it won't recommend any VW diesel until VW proves the fix does not change performance or fuel economy.

Chevy and GM are unlikely to be in any way affected by the VW cheating scandal. GM does not share any engines with VW, nor does it have any cooperation on emissions control technology we are aware of. In its recent advertisement for the Chevy Cruze Diesel Chevy says of its technology:
"Cruze Clean Turbo Diesel emissions are below strict U.S. environmental standards. New technologies including exhaust gas recirculation, selective catalyst reduction, a particulate filter and advanced fuel system components allow the diesel engine in Cruze to generate at least 90% less Nitrogen Oxide (NOx) emissions than previous generation diesels and very low particulate emissions."
