As the age of crude oil gradually finishes and political arrangements all over the world force a continuous reduction of global carbon dioxide (CO₂) emissions, energy efficiency and energy sustainability become worldwide a major challenge for automotive industry. The ambitious European goal of a fleet average emission for all new cars of 130 g/km CO₂ by 2012 afford an overall energy efficiency increase of the entire powertrain topologies. One way to come up to this challenge is surely the electrification of powertrain systems. Nowadays, hybrid electric vehicles (HEV) represent one of the most promising technologies that combine the advantages of high performance, high fuel efficiency and low emissions in combination with a long operating range. In literature exists lots of investigations concerning the requirements of different powertrain topologies along with the corresponding individual requirements of electric motor types.
