Impact Absorption Efficiency and Safety

A unibody uses the stamped floor panel and other parts joined using spot welds to manage impact forces.

Reduced Weight and Improved Fuel Efficiency/Drivability

By stamping thin steel sheet and spot welding multiple panels, it is possible to reduce vehicle weight while strengthening the structure. Consequently, engine displacement can be reduced resulting in improved fuel efficiency. In addition, brake and chassis parts wear is reduced.

Manufacturing Efficiency

Unibodies are manufactured using automated systems such as welding robots, saving labor and resulting in significantly higher production efficiency.

Freedom of Design

Recently it became possible to stamp a high quality steel sheet for body outer panels. Because of this, the steel sheets can be bent and formed into a wide variety of shapes and combined together. Also, it enhances design freedom. For an example, by shaping the floor panel in an optimal way by drawing (stamping), it is possible to lift the floor surface to provide more legroom. This design provides maximum passenger compartment space even in smaller vehicles.
