FIAT 500 on NEDC, WMTC and EDC Some preliminary observations HC emissions (g/km) depend strongly on the first seconds (ca. 60 sec.) of the test cycles CO emissions are related to the first seconds and to the high speed sections of the test cycles Both HC and CO emissions show limited correlation with the “dynamicity” of the test cycles NOx emissions, in addition to the first seconds, appear to be more correlated to the dynamicity of the test cycles
