It seems the small turbo engines are well matched to the emissions test cycle. But in real world driving, they get pushed very hard by drivers. That pushes up operating temperatures and sends real world emissions well above the test cycle results.

So it is kind of like schools teaching to the test, because that is how results are measured.
1996 B4V, Hella E-Codes, GLX leather, 02A 6 speed conversion w/.71 5th and .588 6th gear, A4 shift linkage by Matt-98AHU. 11 mm pump by Oldpoopie. Now, GTC1549VZ turbo by Whitbread. TDtuning, 24 lbs. boost, 162 hp, 285 lb/ft tq. Smoke Free (9/18/15). Koni Yellows and Big Brake 5 lug conversion.
