Two electric units with less than one year of operation (E1a and E1b) and two diesel units were studied, one of them Euro V (C1), with less than one year in circulation and the second with more than five years of activity (C5). Measurements were made at the Victor Borrat Fabini Racetrack, located in El Pinar.
Measurements were made in three scenarios:
-unit on, but stopped (vehicle idling)
-unit at start (0 to 25 km / h)
-drive at constant speed of 10, 20, 30, 40, 50 and 60 km / h
