I just purchased a Golf Sportswagen TDI August 30...two weeks later the news hit. Seemed really bad, but I really wanted to know: "Just how much pollution is my TDI putting out compared to regular gas cars on the road?"
Let me know if my thinking seems right, because the news isn't good.
Searched all over the web and finally found the EPA test results for cars tested in each year. The document for year 2015 "Certified Vehicle Test Result Report Data (XLS)" in http://www3.epa.gov/otaq/crttst.htm shows those results. Here are some random examples (I just found 4 cars I recognized), along with the Jetta TDI:
Ford Explorer: NOx=0.01300, CO=1.67000
Mini Cooper (5 Doors): NOx=0.01550, CO=0.39000
Dodge Dart: NOx=0.02000, CO=0.85000
Jeep Cherokee: NOx=0.01300, CO=1.39000
Jetta (gas): NOx=0.0149, CO=0.3770
Jetta (diesel): NOx=0.03100, CO=0.0100
The Dodge dart is the worst offender, with a NOx of 0.02000 g/mile. Thus if my TDI is doing 15X the max emissions (.05), then it is equivalent to 37.5 Dodge Darts on the road. If we compare it to the best (the jeep or explorer???) it's like 57 jeeps/explorers of NOx emissions.
It is like my worst nightmare...
