This paper investigates the effectiveness of using CVT (Continuous Variable Transmission) in Samand automobile.  For this analysis, the conventional Samand and a Samand equipted with CVT are modeled and simulated by using Simulink based software (ADVISOR) and the performances are compared.  This analysis includes the effect of driving cycle, fuel consumption and the efficiency of components of the power train.  The results show that the fuel economy is increased while using CVT.  Finally, the overall cost analysis for incorporating CVT is done and the economical advantage is discussed.
