ABSTRACT
The core element of any car is the body structure. The body is an extremely important part of any automobile for a number of reasons and demands key design considerations. The body should connect all the components, house the drivetrain, as well as provide crash load paths. Additionally, the body structure should be able to carry and protect passengers as well as cargo. Lastly, the body structure should be joinable with other components in addition to being lightweight to provide optimum fuel economy and performance. The following are the three main design concepts. However, tubular space frame design and backbone chassis dsesign are discussed.

Monocoque (or single shell) (Figure 5.2)
Unibody (Figure 5.3)
