In this paper the different motivations behind the development of hybrid cars are examined and various hybrid configurations are illustrated which can satisfy a wide range of different and contrasting user needs. Specific attention is then given to the definition of guidelines for the development of a hybrid car where parallel configuration of the propulsion system allows the fulfillment of two types of mission: short trips in urban areas with zero emissions by only using the electric motor driveline; long highway trips with performance close to that of conventional cars but lower emissions. The corresponding design criteria for a Fiat medium size hybrid car are described together with the propulsion system, consisting of an A.C. electric motor and an ICE, that has been implemented and bench tested. A prototype car has also been equipped with this hybrid system and the driveability demonstrated.
