The topic examined in the present work has been developed in the Electrified Vehicles Product Planning department in Fiat Chrysler Automobiles and deals with passenger vehicles architectures. The aim of this work is to provide a benchmark about the future strategies on vehicle architectures adopted by passenger cars manufacturers in the future challenging context due to more stringent carbon dioxide emissions reduction targets in 2025 and 2030 imposed by the European Union. The investigated timeframe extends up to 2024 in order to identify how car manufacturers will arrange to face the radical transformation in the European automotive market from 2025. The work methodology has started from searching data and information about the car manufacturers architectures portfolio to evaluate past, present and future trends.
