I wonder if my clean diesel is as clean as I think....

Mercedes-Benz’s diesel cars produced an average of 0.406g/km of NOx on the road, at least 2.2 times more than the official Euro 5 level and five times higher than the Euro 6 level. A spokesman for Mercedes-Benz said: “Since real-world driving conditions do not generally reflect those in the laboratory, the consumption figures may differ from the standardised figures.”
Interesting....
Another article did say diesel cars sold by the same manufacturers in the US, where limits are tighter and tests are more rigorous, have better exhaust treatment systems and produce lower emissions

Either way I am still pleased with our GLK 250
