ABSTRACT
The paper presents the method and results of the car tractive efficiency comparative investigations. Both technical
characteristics and fuel consumption values of numerous cars tested in the ECE simulated driving cycles were used as
the input data. On the basis of the obtained data together with simulated tractive energy consumption the correlation
between tractive efficiency and selected parameters of a vehicle were determined. The proposed method also allows
indirect determination of the average engine effective efficiency of a vehicle at variable speed.
