In order to achieve the objectives of this study, an empirical model is developed based on multivariate linear regression analysis to identify key drivers that influence gasoline consumption. In addition, possible impacts of introducing diesel powered saloon cars, as an energy efficiency measure to the passenger cars market, on the future energy demand and associated reduction in GHG emissions are analysed and evaluated using different scenarios. Based on the conducted analysis, it was found that the number of cars, income level and unit gasoline price are the most important variables that affect present and future gasoline demand. The obtained results proved that the multivariate linear regression models can be used adequately to simulate gasoline consumption with very high coefficient of determination. Without the introduction of diesel driven cars, gasoline consumption is expected to rise by approximately
