[social_buttons] VW’s Jetta BlueTDI: 60 MPG, 90% Emissions Reduction for NOx
This newer version of the Jetta will meet the strictest emissions standards in the world—BIN5/LEV2—which are enforced by 5 US states: California, Massachusetts, Maine, New York, and Vermont. BIN5/LEV2 standards severely cap nitrogen oxide (NOx) emissions (0.05 g/mile), one of the two tailpipe pollutants that have given diesels a bad rap (that and particulate matter).
As it happens, Bin5/LEV2 standards are tougher than their European counterpart, the Euro-5, and VW had to custom modify the Jetta BlueTDI for the North American market. NOx reductions were met with internal engine modifications—some of which are “unique worldwide”—and a maintenance-free NOx exhaust trap. Altogether, this system reduces NOx emissions by 90%.
Combining clean emissions with a road-tested fuel economy of up to 60 MPG highway could make this a winner in the US. Dr. Ing. Jens Hadler, Director of Volkswagen Powertrain Development commented:
[H]igh fuel prices and a dramatic change in environmental consciousness means that diesel is becoming more and more attractive for American drivers every day. This is why many customers, especially in California, have been waiting for a super-clean diesel like our BlueTDI. I think this motor will help the diesel get its big break in America because it consumes so little and yet can go such long distances on a single fill-up. And in a country as big as the United States, this is a priceless advantage. On the highway, for example, this engine can reach up to 60 miles per gallon. This is an improvement of 12 percent over its predecessor, which had a lower capacity and higher emissions.
