Widespread adoption of diesel power in the US took a step closer this week when VW announced its new Bluetec diesel engines – billed as the world’s cleanest diesels.
Developed in conjunction with Mercedes and being previewed in the Tiguan SUV concept they have been designed to meet stringent US emissions regulations, including the toughest of all in California. Most current diesels do not make the cut.
Bluetec promises to reduce harmful nitrogen oxide (NOx) emissions by up to 90 per cent compared to current diesels by utilising newly developed particulate traps.
VW also hinted that the techniology could soon be finding its way to Europe, while Mercedes is expect to put the new-style engines in the ML, GL and R-class in the US in 2008.
BMW was originally part of Bluetec 's joint venture, but recently decided to pull out of the development partnership.
