In the present paper, we make a literature review concerning existing models for electrical, hybrids and fuel cell road vehicles. We identify MOVES has being a future powerful model, also including fuel life cycle calculations, and ADVISOR has being the most widely-used model. Both have alternative fuel limitations, because do not consider for example, biodiesel and ethanol. ADVISOR was used to compare the energetical and environmental performance of alternative powertrain systems against conventional vehicles, under several traffic conditions (urban and highway). The obtained results allowed to identify disadvantages/ limitations of the model, concerning series hybrid simulation (the possible energetic flux of ICE feeding a generator that in turn feeds directly the traction electrical motor avoiding the loss of efficiency caused by the flux passing trough the battery charge/discharge process is not considered) and concerning HC, CO and NOx emissions (inconsistent emission results where found). Based on the existing models, we briefly explain our goal concerning the creation of a new model RVS-Road Vehicle Simulator. Key recommendation of this study is that more experimental on-board data is needed, including conventional and hybrid technologies, and with various duty cycles that include A/C use, road grade, variability in real-world driving cycles, and so on, as a basis for calibrating existing and future models.
