Packaging, in the context of motor vehicles, implies the design and organization of dimensioning volumes i.e., the definition of the primary dimensions (hard points) of a vehicle, which determines the concept. After the layout and dimensioning of the assembly groups that determine the concept, constructional features especially ergonomics, functionality, vehicle safety and manufacturing techniques are then considered.
Package is influenced by the vehicle concept and also by the desired styling. It also gives specification regarding the positioning and dimensioning of the:
          Passenger cell:
Dimensions for seating position of passengers, adjustment travel of the seats and seat-backrests, minimum values for headroom with respect to the vehicle structure
          Supporting structure:
Distribution and size of all main structures, points of belt anchorage, bumpers (height and projection)
          Position and space requirement of functional units:
Form contour of the aggregates, engine and luggage compartment, wheels and axles with respect to the necessary ground clearance, for different loading conditions, free space up to the outer shell, tank and spare wheel, trunk (up to the ground and also up to the contour), lighting devices all round the vehicle.
For dimensioning of the supporting structure and the safety-relevant components, decisions must be finalised as to the basic material.
