Thus the fuel requirements and the level of pollutants exhausted by the vehicle are reduced, and can be controlled. Various Regenerative Braking Systems include Mechanical Flywheel RBS, Elastomeric Flywheel RBS, Hydraulic Power-Assist RBS, Ultra capacitor RBS, etc. In this paper, a typical mathematical analysis of the performance of Mechanical flywheel RBS, Elastomeric Flywheel RBS, and Hydraulic Power-Assist RBS has been studied on different car models based on current research, and a comparison of the efficiencies and fuel savings by these systems has been done taking into consideration, a basic Volvo car model. Analysis shows the efficiencies of Elastomeric Flywheel RBS, Hydraulic Power-Assist RBS, and Mechanical Flywheel RBS will be in a descending order. Key words: Efficiency, Elastomeric Flywheel RBS, Hydraulic Power Assist RBS, Mechanical Flywheel RBS, Regenerative Braking System.
