On page 39 of the latest issue of Automotive Magazine the piece entitled "The squeaky clean diesels" has this statement:
"To sell diesel cars and light trucks in the United States after 2008, manufacturers must reduce exhaust soot (particulates) by 50 percent and nitrogen oxides (NOx) by 65 percent from levels achieved by the new, very clean Mercedes Benz E320 BlueTec. So far, only General Motors and Honda have claimed the ability to do that."
On the previous page was an article on the new E320 BlueTec and other MB diesel models coming soon. As we know the 2007 E320 is not 50 state compliant to 2007 standards without AdBlue; this article says that the 2007 GL, R, and M-classes with AdBlue will be fully compliant when they come out next year.
My understanding is that the 2008 TDI will also be 50 state compliant (God-willing) to 2007 standards when it comes out. But the first quote says that after 2008 the emission standards will get even stricter by over 50%! If that's true, then the 2009 TDI will need to be >50% more efficient at reducing emissions than the 2008. Is this really the case?
