So... Euro V 0.230g/km, Euro VI 0.170g/km

The US figures are in mg/mile - so Euro VI is about 27mg/mile, and
Euro V is about 36mg/mile. Both are way down in the lower bins. Even
Euro III's .56g/km = 89mg/mile. Hell, even 1992's Euro I had a cap of
HC+NOx of 0.97 = 155mg/mile - within the current upper US bin, and
only 5.5x the Euro VI figure, let alone the alleged "40x"...

Could be that the 40x is what the people who discovered the anomaly
found during 'real-world' tests vs. the permitted output for the band
that the cars were in.

So the "real world" emissions are six or seven times what was permitted
nearly 25 years ago...?

No, I don't buy it. I don't buy that VW's engineers are uniquely
incompetent and disingenuous, either.

But why would VW basically admit to fraud if they did not believe themselves to be guilty? They did not try to spin it in a PR way at all.

One article I read said that most diesels in the US use urea exhaust treatment, but VW did not include that on the 2.0 TDIs making out they have superior engine tech that did not need it. Of source that engine tech (just more exhaust re-circulation during "test" mode ?) was not active in normal driving.

I also heard it reported that they did include Urea treatment, but it was switched off during normal driving so it would not run out.

Not sure which is correct.
