The automotive industry is currently undergoing a significant transformation due to increased attention to pollution levels. The European Commission is aiming for a zero-emission scenario by 2035, and as such, stricter EURO regulations will be implemented to achieve this goal. Light-duty vehicles and passenger vehicles are the primary focus of this process. The compliance to the latest standards is strongly affecting to the engine mechanical design with the need to introduce new configurations. The most widely adopted solution is hybridization, which involves coupling an electric machine with an internal combustion engine. This requires a substantial redesign of the transmission system to manage torque split and accommodate the new architecture.
