I would agree with you, with one minor caveat, I think they do REALIZE- which is the reason why they make them do it!!! They also realize that for literally ANY population they care to let passenger diesels expand to (say 12% as 5/10/15 year targets) they can not make the statistical correlation that whatever emissions D2 does put out will be MORE than a like populations of diesels. They have not been able to make the case for the 12% SUV population, and they have not been able to make the opposite correlation for the hybrid population.

The Cummins light duty diesel will be ready for the 2010 model year in the Ram 1500, and it will be 50-state legal. Automotive News stated this week it will be the 4.2L V6 version instead of the 5.6L V8... still more than adequate with preliminary ratings of 270 hp and 420 lb-ft of torque (more than the revised Hemi at 407).
 
Tested a couple of years ago in a Dodge Durango, the V6 turbodiesel averaged 20 mpg city and 25 highway.

Nothing to write home about.
 
We need average MPG in the 30's.

I agree, this is still not good enough. How about a 3L to 3.5L V6 That should provide all the HP anyone using a ½ ton pick-up should need and may give you 30 to 35 MPG hwy.

... Well the reg bodies don't appear to REALIZE that EGR causes: increased soot, increased engine wear, increased GHG, increased initial cost, increased maintenance cost, increased fuel consumption, decreased oil change interval, increased vehicle weight, and they also don't seem to realize the great advances in fuel injection, turbocharging, engine weight, particulate traps, and even their own ULSD fuel, but keep adding regs that are long passed the point of diminishing returns, and don't even make the general public consider (with incentives) (like trading a little NOx for a bunch of carbon) the very low carbon footprint, smaller, four cylinder, Diesel, sedans, that are not availiable because of the regs.

The 5 cylinder diesel in my Mercedes Sprinter was a great engine. It pulled that 8500 lb RV around up and down hills with ease. It was also rated to tow 5k lbs. If they put that engine in a regular van or 1/2 ton PU it should get 35 MPG out on the highway. It is the mentality in the auto industry that we either have to have a vehicle that is fast or we are going to tow a 10,000 lb trailer. Most people just need to haul a few cement blocks, bags of concrete and sheets of plywood.
 
The new Sprinter has the V6 Mercedes diesel and the mileage dropped from 25 MPG to under 20 MPG. We sure are making progress in this country. It will be interesting when the CAFE mandates run up against the EPA/CARB wall of worthless regulations.

Yes, indeed, CO2 emissions statement is mandatory for all new cars in EU and has been for some time now. Numbers are in g/km............after all, Europe is Metric, (apart from UK & Ireland - sort of).
 
Want some CO2 examples ?
 
o Audi A4 3.2 V6 Quattro = 250
 
o Audi A4 3.0 TDi Quattro = 204
 
o Audi RS4 V8 Quattro = 324
 
o BMW 335i = 231
 
o BMW 335d = 200
 
o Lambo Murcielago = 400
 
o Mini 1.6 D Cooper = 118
 
o Mini Cooper S = 164
 
o VW Jetta 2.0 TDi 140 = 148
 
o VW Jetta 2.0 TFSI 200 = 189 new TFSI's are getting pretty clean.
 
o VW Polo 1.4 TDi Bluemotion = 99 (non-Bluemotion = 119)
 
o Volvo S80 D5 AWD = 182
 
o Volvo S80 4.4 V8 = 294
 
o Audi Q7 4.2 V8 FSi = 326
 
o Audi Q7 4.2 V8 TDi = 294
 
o Cadillac CTS 2.8 V6 = 278
 
o Chrysler 300C 3.0 V6 CRD = 215
 
o Chrysler 300C 5.7 V8 Hemi = 287
 
o Chrysler PT Cruiser 2.2 CRD = 185
 
o Chrysler PT Cruiser 2.4 = 231
 
Just a small cross-section that will allow folks to postulate all sorts of "Aha, but......." comments. Have fun with 'em and if you'd like some specifics I'll try to oblige.

Well if your post is any example, it is easy to see that EPA/CARB (states) CONSISTENTLY has said and will continue to say :
 
1. that higher emissions are better than LOWER emissions!!!! (250 is better ( aka LESS than) 204, etc)
 
2. They also say that burning a min of 2x to higher dirtier fuel (RUG to Pug 30 ppm) is better than burning cleaner fuel (ULSD 15 ppm to ZERO)
 
2b. They make the dirtier fuel (RUG to PUG 30 ppm) CHEAPER per gal to boot !!!
 
3. They also say why burn less less (50 mpg) when MORE will do (30 mpg) !!!
 
( we have been saying this stuff ALL ALONG !!!!! Now we know at least one reason why K-12 US schools impart such wonderful mathematics awareness in the USA general populations.)

2009 Jetta TDI by brakvica

besides the fact that the Jetta is getting not great gas mileage; and the fact that diesel is 30% more expesnive than gasoline (which wipes out what little benefit you are getting from the 29/40 gas mileage)...
 
the real issue is that the Jetta is being built in the Pueblo, Mexico factory which means it will be plauged with the same quality problems as the rest of the VWs that come from Mexico
 
there is NO cost ebenfit to buying this hunk of junk

from what I understand , the quality of vehicles built in mexico often exceeds that resulting from european manufacturing and that has been the case for some particular model years for VW.
half of my 4 Un-Clean TDIs (03, 05, 06, 06) were built in mexico and they are awesome with regard to quality. New Beetle had a couple of tough months as dealer searched for a water leak, but that was the only annoying reliability issue.
So all those VWs have been reliable, but I have not driven one past 100K yet.
