Electrifying Boost: Design & Optimization of a Hybrid Powertrain for the Rush SR

Abstract

This thesis details the integration of a hybrid powertrain into the Rush SR, a compact, gasolinepowered race car, focusing on the incorporation of the ME1616 electric motor into the vehicle's drivetrain. The project aimed to develop a bolt-on hybrid kit that owners can independently purchase and install. Utilizing design criteria from Rush Auto Works and first-order calculations of anticipated performance gains, the selection of the electric motor was guided meticulously. Using Computer-Aided Design (CAD) software, the electric motor was integrated into the vehicle’s architecture, with a detailed model developed to ensure alignment with the existing structure. Finite Element Analysis (FEA) was employed to validate the design of critical components, confirming their ability to meet the rigorous demands of competitive racing. A comprehensive manufacturing plan and Bill of Materials (BOM) were established to facilitate the immediate steps for building and implementing the electric motor and power transmission systems. This project not only aims to enhance the performance of the Rush SR through hybrid technology but also serves as a practical demonstration of hybrid system integration in performance-focused, small-scale vehicles.
