Energy consumption and exhaust emissions are the most challenging issues in transportation that car makers and policy makers have to deal with. As a consequence, several technologies have been developed in order to limit fuel consumption and pollutant emissions. So far, some of the promising technologies for passenger cars are hybrid electric vehicles (HEV) and, later on, plug-in hybrid electric vehicles (PHEV). The study presents an assessment in terms of energy consumption and carbon dioxide emissions for gasoline HEV and PHEV compared to Internal Combustion Engine (ICE) conventional gasoline and diesel vehicles. This comparison intends to assess carbon dioxide and energy consumption reduction ability of PHEV for several countries or geographical region (EU 15, USA, Japan, and France). The energy consumption is computed with a detailed drive train model taking into account different driving patterns.
