The migration to more centralized architectures has started and will accelerate from 2025. While the industry generally agrees on the need to evolve from distributed to centralized architectures to support Software Defined Cars and new business models such as paid updates and OTA, this migration is complex and disruptive. The pace of adoption will differ based on the portfolio of OEMs, ranging from baby steps to giant implementation strides. The E/E Architecture revolution is also disrupting the supply chain. Whilst new components and specifications emerge, some components will become obsolete and some standardized. In this presentation, S&P Mobility describes - with a number of real examples - how the industry will transition from distributed to fully centralized architectures.
