Just edited to clarify. The current generation makes less NOX especially when tested on a front wheel dyno as done by the EPA. Evidently VW programmed the steering and wheel speed sensors to detect if it is on a real road or a "rolling road" as the British call it, to put itself into low NOX/run wimpy mode
