This paper compares the sustainability of three new technologies in vehicular transportation which consist of (1) innovations in the fuel the vehicles use and (2) innovations in the vehicle design itself. An array of vehicle platforms, which consist of different vehicle designs and fuels types, are modeled and a life cycle analysis (LCA) is performed to find the total energy consumption and emissions of each model. As high energy consumption and pollution become growing concerns, this paper aims to provide a better understanding of where new advancements in vehicular technology should be focused.
