Guess US EPA don't want these in America, sad!
Nope.
Try guess again.

NHTSA and the government big wigs
Exactly, the government doesnt want these epic mpg cars here as ppl will buy them, hen oil corporations will lose money because less gas is being sold, hence the government will make less tax money AND a number of big government ppl own parts of oil corporations and in time they wouldnt earn as much money because the oil corporation made less money
NHTSA? It's don't make sense to me,
USA have Legacy, Outback, Forester, and Impreza for gasoline engine, but Legacy, Outback, Forester, Impreza for diesel engine nope. They are same body, just difference engine and that's it.
EPA nope? NHSTA nope?
then who?

I think the new diesel powered Subby are not met EPA requirement in California.
What's about other 49 states?
That was 2007 and the reason was simply because of emission issues.
Mercedes ML320 CDI banned in some states. Is BMW next?
The main reason is that diesel engines without the filtering devices are much more dirtier than the gasoline versions which is why they don't pass the strict emission rules in California. Europe, on the other counterpart is more flexible and have different society. It is very hard to get a diesel to approve CArB rules. Mercedes did make it with one model called bluetec diesel and the VW TDI as well. Subaru just couldn't figure it out, pretty much. The mpg ratings with the Subie is impressive.
Turbocharged or supercharged used on both gasoline and diesel powered engines, will create NOx (nitrogen oxides) emission that the temperature in the combustion chambers (in cylinders of the engine), reach over 2,500 degree F and cause by too lean air/fuel mixture and high compression ratio. Diesel engines with turbos will produce good fuel mileage I think.
Diesel powered vehicles are more pollutes than the gasoline powered vehicles but I smogged a 2009 BMW X5d, Twin TC diesel powered, I saw the VECI says 5 cat converters I think ( I 'll find out tmw). I smell no diesel fume from tailpipe like little smell from newer gasoline powered vehicle. Wow.
Agreed, somehow I think of the diesel Subby that cant met the CARB is because they (engineers) are coping with the excessive emissions situations. If you want to lower the NOx level, is you have to increase fuel meterings by change the mapping (software in computer) but they will fail for little black puffs from tailpipes. And want to lean fuel meterings then will get bad NOx but I caught you for cat converter issues, I think they should do something up with cat converters (maybe they have troubles with tightest underbody spaces for addition cat converters) to control the NOx levels.
Yeah. Most new transit buses have particulate filters installed to reduce dirty diesel exhaust, thus cleaner exhaust. I think they remove them and clean them then put them back for re use. Some transit buses have 4 cylinder turbo diesels and many of them use 6 inline diesels. One of the hybrid transit bus which is articulated, 60 ft long and has a cummins diesel hybrid 4 cylinder engine which they have in Seattle. It gets about 4.5-5 mpg average.
