What is the process for developing a new vehicle platform/architecture?

Platform development involves: Strategic planning (defining vehicle range to be covered, target segments, regional requirements), architecture concept (hard points, scalability ranges, technology integration), simulation-based optimization before hardware (crash, stiffness, NVH), manufacturing integration (plant capabilities, investment requirements), supply chain development, validation strategy, and program timing integration. Key decisions include wheelbase/track ranges, powertrain compatibility (ICE, hybrid, BEV), suspension geometry family, and electrical architecture. Development takes 3-5 years before first vehicle launch, with platform life of 7-10 years across multiple model generations.
