From the article link posted:
"Sidebar- Perhaps the only other carmaker as committed as VW to offering diesels in America is Mercedes-Benz. Last month at the 2006 Detroit Auto Show,
M-B confirmed that it will offer its next-generation diesel technology, known as BlueTech, here starting this fall in 2007 models. ...
Bluetec employs two new technologies that allow this diesel engine family to meet the new EPA requirements for NOx and particulate matter emmissions. NOx reduction is accomplished by way of either water or urea injection (depending on the appilcation) into the combustion chamber. The additional storage tank required by this system will be filled my M-B technicians during routine maintenance every 10,000 miles. Particulate matter (soot) will be removed from the exhaust stream by an in-line particluate trap, which according to M-B, is maintenance-free."

"What does that mean for the future of diesel VWs here? While VW insists it will remain committed to offering a diesel option here, the cost of compliance may ultimately determine its fate. The TDI is already a $1000 premium option over the standard 2.5-liter gas engine. Will buyers pay an even higher premium for an ultra-clean VW diesel? If not, is VW willing to subsidize the cost of this technology as a matter of principle? Ultimately, a change in tax-credit policy for ultra-clean diesels will probably be the deciding factor."
