Volkswagen unveils 2008 Jetta TDI with Bluetec clean diesel technology
Washington, D.C. – At the Washington auto show, Volkswagen unveiled the 2008 Jetta TDI equipped with a new Bluetec diesel engine that will meet the most stringent “TIER 2/BIN 5” or “LEV II/LEV” diesel emission standards which require limiting nitrogen oxide (NOx) emissions to 0.05 g/mile.
The clean diesel Jetta TDI meets the lowest emissions standards without the use of urea injection. Instead, a nitrogen oxide storage catalyst reduces NOx emissions by up to 90 percent. The engine management system in the Jetta changes operating modes periodically to treat the NOx that has been stored in the catalytic converter. A particulate filter in the exhaust system further reduces emissions.
The 2008 Jetta TDI will be the first VW vehicle in North America to use Bluetec technology licensed from Mercedes-Benz. It will be available in the Spring of 2008.
