Part 4/14:
A major question arises: can OEMs develop plastic body panels that meet crash safety standards while significantly reducing costs? Hans responds affirmatively, recalling past examples like a Saturn vehicle with plastic panels and discussing the feasibility of using plastic or thinner stainless steel for outer shells. The key is internal structural strength—most of the safety and rigidity currently provided by steel frames can be maintained internally, allowing outer panels to shift to lighter, cheaper materials. Even carbon fiber is considered as a viable alternative, provided manufacturing can be scaled affordably.
