It's simple enough to go to the EPA OTAQ WWW page and download a
spreadsheet showing emission certification levels for vehicles sold in
the US.

http://www.epa.gov/otaq/crttst.htm

Search for the diesel Jetta and you'll find NOX emissions of .55
grams/mile, and HC emissions of .28 grams/mile.

Then search for c2500 and you'll find a heavy duty gas pickup with NOx
emissions of .1 g/mile and HC emissions of .017 g/mile.  The pickup,
with the mileage you'd expect from an 8 liter v8, is far cleaner than
the anemic diesel jetta with it's cute little 1.9l diesel.

The 2007 certifications aren't out yet but I doubt low sulphur is going
to make much difference to HC or NOx.

Diesel engines have their place towing/hauling, but not in making the
air any cleaner.  I don't understand how diesel has an image of being
environmentally friendly.  "Dr. Z" may claim that the Liberty is the
cleanest diesel ever, but in fact it's dirtier than the jetta.
