What is a vehicle platform/architecture and what are its business benefits?

A vehicle platform/architecture is a common set of structural components, hardpoints, and systems shared across multiple vehicle models. Key shared elements include floor structure, suspension geometry, powertrain mounting, and electrical architecture. Business benefits include reduced development cost (spread across models), shorter development time, quality improvements through validation across higher volumes, manufacturing efficiency (shared tooling, common parts), and simplified supply chain. Modern modular platforms (like VW MQB, Toyota TNGA) can span vehicle sizes and powertrain types.
