For as long as Motoring has been Motoring, which is approximately 110 years ago, it has been unquestionably known that an automobile chassis is a structural support of dynamic elements designed and prepared to absorb terrain unevenness as well as to make the vehicle onward motion more stable.

The chassis’ most important mission is also unquestionably known: to stay in place as firmly and strongly as possible ... that is to say, with the highest possible rigidity.

On the other hand, it is clear that approximately 5 or 6 elements are held on top of the chassis. They are built and designed especially to get deformed, some of them to adapt to compression and expansion and others, to bending and torsion.

These are the elements to be deformed:

• Rubber Tires.
• Foam Insert.
• Shock Absorber.
• Shock Absorber Spring.
• Torsion Bar.
  
  If the chassis adopted any of these behaviours, we would be facing a serious problem, since it would be not precisely functioning as a chassis that firmly consolidates the fastening of the other elements.
  
• If any element has to absorb ... it is the Shock Absorber ...
• If any element has to resist each fall after a jump ... it is the Shock Absorber Spring ...
• If any element has to flex or bend ... it is the Torsion Bar ..
