In this work, a comparative analysis of five types of urban passenger buses powertrains was carried out in three countries of South America: Argentina, Chile and Brasil.The study is carried out within the WTW scope and applied to an urban passenger bus fed with their respective fuels (or energy vectors) obtained from different sources with this different propulsion systems: Internal Combustion Engines (ICE) fed with Diesel, Fuel Cell Hybrid Electric Vehicle (FCHEV) fed with hydrogen, Battery Electric Vehicle (BEV) fed with electricity and Hybrid Electric Vehicle (HEV) fed with diesel. The well to tank step was made for present and future scenarios. Additionally, as the buses energy consumption and emissions (TTW stage) vary significantly due to driving conditions (i.e. congestion, geography, and number of stops) and propulsion configurations (i.e. degree of hybridization, battery type, and fuel cell type), the tank to wheel analysis was performed using dynamic models of vehicles, two different driving cycles and four ranges (100, 200, 300 & 400 km).In order assess the different hypotheses for systems, range, cycles and scenarios; a multiphysics indicator (Integrated Sustainability Index), valued between zero and one was used.
