The technological advancements of internal combustion engines, batteries, and electric propulsion technology have reached such a level that they bring a new dimension to the potential of hybrid propulsion systems. Partially or fully electric vehicle propulsion drivetrains receive significant attention when considering the future of mobility, as they have the potential to reduce the sector's greenhouse gas emissions and dependence on fossil fuels and hopefully mitigate climate change. This paper aims to design a hybrid powertrain for a conventional passenger vehicle that can cover the performance requirements of everyday average urban usage with electric propulsion to reduce consumption and emissions and improve sustainability. It aims to present the performance requirements of the vehicle based on road measurements conducted under various traffic conditions and usage environments. The energy savings achieved through the auxiliary powertrain will also be evaluated based on real-life, everyday usage conditions. Finally, the paper introduces a Life Cycle Assessment (LCA), which compares the original conventional propulsion system with the new hybrid powertrain.
