Hybrid powertrains for vehicles have been widely developed in recent years and spread in the market with the double goal of reducing fuel consumption and improve performance. The integration of traditional internal combustion engine and electrical system can occur according to different layouts and control logics and may affect vehicle dynamics. The employment of a hybrid layout enables the possibility to recover energy while travelling thanks to the use of the electric motors as generators, thus increasing the energy available and enhancing the electric driving range of the vehicle. In this thesis work a parallel hybrid supercar has been analysed, investigating how the powertrains with which it is equipped cooperate.
