Ok, now we understand the confusion:

Steve is talking about NOX emissions and Tachi is on about greenhouse
gasses.

 http://www.epa.gov/otaq/crttst.htm NOX data
 http://www.fueleconomy.gov Greenhouse gas data

But the NOX issue is due to the sulfur content in the fuel, no? And the
newest small diesel cars even filter that out and will have lower NOX as
well as lower everything else.

Finally, I may be reading this wrong, but in the crttst.htm data, it would
appear to me that the VW is lower than most standard cars on NOX anyway. And
this is the car that they banned in California because it wasn't clean
enough?

I have a friend who purchased one out of state (which is legal) and is
running bio-diesel in it. I wonder what the emissions are from that? And
does it matter, since the plant has to have absorbed all that when it was
growing? And if we can't have diesel cars, how will we brew bio-gasoline?

Over all the future of diesel cars looks good to me.

Rebuttals?
