The main goal of this research is to introduce and validate microscopic fuel consumption models named Virginia Tech Comprehensive Power based Fuel Consumption Models (VT_CPFMs). These models estimate the rate of fuel consumption for light duty vehicles on different roads. The VT-CPFMs are established to be easily calibrated using publically available data without necessity to collect in-field instantaneous data. The study additionally determines the relationship between different speeds and rates of fuel consumption. Furthermore, a model was generated to calculate the fuel consumption as a function of speed to get the most economic speed range. Driving with such speeds achieves a high rate of fuel savings and thus reduces the operating cost. Moreover, the study indicated the influence of different acceleration types (mild, normal and aggressive) on fuel consumption using MATLAB® model. Finally, it was found that the results of fuel consumption obtained from the VT_CPFMs can be applied on Egyptian roads. It was also proved that optimal speeds range from 60 to 80 km/h. The study demonstrated that as the level of aggressiveness for acceleration maneuvers increases, the fuel-consumption per maneuver decreases because the vehicle spends less time accelerating
