      Automotive market had to deal since 2019 with years of turbulences and transformation. Its growth has been stopped in 2019, due to an accelerated transformation of consumer behavior, environmental awareness and local regulations, 2020 was turned upside down by the pandemic, 2021 was marked by different component and material shortages, and 2022 started with the massive challenge of energy.

      In this hard conjuncture, automotive industry is experiencing a deep transformation, starting with the run for the best successor of internal combustion engines, which is challenging the traditional market players. They face with a new market structure and difficult employment challenges.

      Bosch is in very good position to turn these challenges into opportunities to gain new businesses. With its comprehensive portfolio of powertrain solutions, Bosch will contribute to save our environment and at the same time offer economical solutions, while increasing the driving pleasure. Bosch will also, thanks its expertise in autonomous driving and clouding, contribute to a safer and more relaxed driving. At last, Bosch expects to gain businesses with new market players.

      In this transformation, there are also new opportunities for forged parts. In the powertrain application, further development of gasoline injection will increase demand of stainless steel forged parts. Electric engine rotor shafts are a further example of growing business. Moreover, forging parts are now chosen for other reasons as well-known mechanical properties. Aluminum forged parts offer the tightness even more expected for hydrogen driven systems and electrical systems working under high voltage current, which require to be cooled down with liquid circulation. Furthermore, aluminum good corrosion resistance and surface quality is welcome for sensor housings for autonomous driving. Lastly, we see market volume spread and need for tailored flexible solution as a chance for forging solutions.

      Expectations will accompany opportunities. Additional processes competencies, like machining, surface and heat treatments, will be an advantage for the supplier, but also mean more responsibilities. In addition, new market players expect more agility in project management. At last, autonomous driving relies even more on the performance of the systems, 0 failure expectation will keep gaining in importance. In a even more digital world, digitalization of factory has to be seen as a chance to face all these challenges.

    • 14:30 Evolution of materials selection from internal combustion engine (ICE) to battery electric vehicle (BEV)14:30 - 15:00Fabio Massa - Stellantis

      Battery electric vehicles (BEV) are becoming more common in the transportation sector in recent times. In fact, BEVs can extensively reduce the atmospheric pollution and the greenhouse gas emissions produced by motor vehicles. As the present trend suggests, BEV is likely to replace internal combustion engine (ICE) vehicles in the nearly future.

      However, the production of BEVs vehicles is still limited due to some issues, such as the high weight of the battery packs that is directly proportional to the autonomy.

      In this work, the state of the art of ICE vehicle powertrain development will be analysed and compared with the BEVs vehicles; moreover, the latest innovations in the field of materials engineering of car body design used to optimize the autonomy of electric vehicles will be discussed.
