This controversy was in the making because politicians were making demands that the technology and science couldnt keep up with.
In this case it was a couple hundred dollars per car for urea injection.
The VW’s with urea injection meet the specs.

Exactly right. Politicians don’t give a damn about trifles like physics.
The regulations should have been pollution per mile, not pollution at idle (out the tale pipe).....................
VW did it right. pollution at idle was good AND pollution per mile was prob better than most.
At the time the cars in question were being built, the emissions standards for Diesels in the US were actually stricter than those in Europe. IMHO, the EPA had decided that Diesel cars needed to be eliminated.
This is just one of many reasons why the EPA needs to be throttled.
