During operation on road and due to gradual ageing ofa vehicle, the formation of gaseous pollutants undergoes certain evolution. At the start of the vehicle life the evolution is influenced mostly by the run-in period of the driving mechanism. Motor vehicle manufacturers state that the vehicle run-in period ends after the vehicle has run from 3,000-15,000 kilometers depending on the engine type and transmission mechanism. During the run-in period the fuel consumption decreases and the production of emissions slightly changes, which consequently influences the emission factor. (The emission factor is understood as the ratio between the pollutant produced and the amount of consumed fuel). A theoretical value of the difference in the fuel consumption between the new and run-in vehicle is about 8% in favor of the run-in vehicle. The European legislation does not specify after how many kilometers the vehicle stops to be considered new. This can lead to disputes when testing emissions from the new vehicle and those from the vehicle having the control software already installed. The contribution outlines apossibility of determining the coefficient for calculation of emissions and fuel consumption for the first tested vehicle and for the one that has coveredfrom 60 to 300 kilometres. It may contribute to the optimization of the control software installed in the vehicle.
