It is more than NOx it is also Particulents and the life span of the emissions equipment. California requires the emissions equipment to be covered for something like 100,000 miles and filter traps aren't in most cases. They require replacement or servicing at much shorter intervals.
 
But we have had European cars before and they are hardly a booming success in most cases because our driving style and the distances we drive seem to be harder on them than the countries they come from.
 
But the real point it that Europe and Asia managed to increase fuel economy far more than the US without CAFE. This fact alone should make one question the value of a government system that doesn't work as well as the free market system in countries not known for free market but government controls.

One simple mnemonic, ULSD. The EU could see that gasoline was never going to result in good economy. So they let the automakers solve the problem. They built high performance diesel cars and the government mandated Ultra Low Sulfur Diesel. They worked together without getting the cart before the horse as the EPA & CARB have done. The gap keeps widening between diesel and gas engines. I would say a current 2L diesel engine will be 35% better on economy than the best 2L gas engine in the same vehicle.
 
That is the reason they have so many cars running around getting 44 MPG and we have a couple complex hybrids.

the EU DOES have "CAFE", it is just a requirement for reductions in CO2 emissions instead, like the inverse of CAFE, but with the same effect.
 
And the new standard is 120 g/km (about 44 mpg), which they are saying it looks like the automakers will not be able to meet by next year when it is supposed to be in force, so they are going to be discussing this in the near future. This, per the latest issue of R&T. There are even stricter fuel economy requirements scheduled for the future.
 
If the most "draconian" CAFE proposed by our Congress made it into law, we would still be behind the Europeans and the Asians in our FE standards by 2020.

True, but if we added our particulant standards that CARB has suggested Europe would have to cut back on their diesel fleet. I totally agree diesel is more fuel efficient than Gas but even with a great trap it isn't ULEV and not PZEV by any stretch. As stated earlier CARB and CAFE got the cart before the horse. CAFE simply doesn't work in conjunction with EPA and CARB doesn't work with either. I believe we wasted 22 years with both CAFE and CARB.

naw, you're wrong there, the 2009 emissions standard is what ULEV would be today, and the Germans and Honda all have a diesel engine ready to go that meets the '09 regs. VW is bringing theirs to market next March, Mercedes, soon thereafter, and Honda by the end of CY 2008.

I wonder if ULEV will be enough. How about PZEV? I can tell you from experience that there a a whole lot of diesels in Europe that can no way meet our particulant standards. I don't know how that effects the older fleet in Europe but I do know we are simply selling out commercial government and construction fleet to other countries. There was a big article on that in the LA times a few weeks ago. You have to wonder how that relates to real world issues? I think VW could make a Pzev diesel. After all they are in the shop so often they can't be polluting. LOL

I believe like you do that they are working on Diesels and have been reading the sites like

But saying you will meet the standards by 2009 and doing so are questions that have to be seen to be believed.

And the new standard is 120 g/km (about 44 mpg), which they are saying it looks like the automakers will not be able to meet by next year when it is supposed to be in force,
 
That is a proposed standard which was to be met by 2012. It probably won't make it into law because, as you stated, there is a lot of opposition from the auto manufacturers. The current proposed standard that exists is 140 g/km by 2008 and it represents a voluntary agreement between the automakers and the EU, not a mandate. 75% of the automakers selling vehicles in Europe are not on track to meet this voluntary target.
 
One other thing to keep in mind. This is not quite the inverse of our mile per gallon scheme of measuring efficiency. The difference is that diesel fuel has about 13% more carbon per gallon, which means that under this g/km CO2 measuring system a diesel vehicle needs to get about 13% better mpg to meet the same CO2 emission level of a gasoline burning vehicle. For instance if they were to meet this voluntary 140 g/km level then gasoline vehicles would have to get 39.2 mpg and diesels would have to get 44.4 mpg.
 
My point is that Europe has a voluntary form of CAFE that the auto manufacturers are not in compliance with yet the European fleet is significantly more efficient than the US fleet. So as far as CAFE goes the European model is not an example of its effectiveness. There must be something else going on that is motivating drivers.

Well in Europe the motivation for diesel is two fold. Mileage and a tax break. While I don't support our method of taxing people into compliance I do support getting tax breaks to achieve the same goal. As the old saying goes about flies and honey verses vinegar. We have long suffered at the hands of political minorities pushing for taxes to fund their cause rather than rewarding people with tax breaks for helping with a problem. Still one has to question how they will make a diesel that starts our with more Particulents cleaner than gas if people are working on making gas cleaner as well? CAFE simply doesn't address both of these issues.

Tax breaks/incentives certainly are more appealing to the average voter, which is why politicians are more likely to support them. The question I have is how are these tax breaks paid for? It seems to me that there are 3 possibilities. Either a tax hike somewhere else. Reduction in a government service, which is essentially a penalty on whoever was benefiting from this service. Or, the government can choose to simply not fund this tax break and just add it to the deficit, which is a tax hike on the future.
 
Imagine this scenario. What if instead of a tax deduction for children and dependents there was a tax penalty for not having kids? The tax rates could be adjusted so that everyone's tax burden would end up being the same with this method but the psychology would be very different. The people without kids would be wondering why they are being penalized for this. So its easier to sell a tax break even though these breaks end up in higher tax rates for those that don't take advantage of them. So what if everyone took advantage of these tax breaks, wouldn't everyone benefit? Again, I don't see how that's possible.
 
I wouldn't oppose tax incentives and credits for adopting fuel efficient vehicles but they need to be paid for. Since the goal is to reduce fuel consumption what would be the most logical way to pay for these tax breaks? It seems to me that they should be paid for by a fuel consumption tax. That would represent the carrot and stick approach.
