What is vehicle packaging and what are its main considerations?

Vehicle packaging is the process of efficiently arranging all components and occupants within the vehicle envelope. Key considerations include occupant accommodation (headroom, legroom, ingress/egress), component placement (engine, battery, fuel tank), structural requirements, crash clearances, serviceability access, and manufacturing feasibility. Packaging requires balancing competing demands - for example, maximizing interior space while minimizing exterior dimensions, or optimizing aero shape while maintaining visibility.
