The discussion centers on the relationship between density, mass, and the structural integrity of a car. Lowering the mass of a car while maintaining the same volume results in reduced density, which can influence the car's damageability. However, the overall durability of the vehicle also depends on the materials used, such as composites that offer higher strength-to-weight ratios. The cost of these advanced materials is a significant factor in their adoption for automotive manufacturing.

I would depend on lots of factors. Surely you can image material such as composites that are MUCH stronger than existing car material but also lighter? Such are not used because they are prohibitively expensive, but ...Sundown444 said:So if a car were to somehow have its density lowered by lowering the mass, but keeping the volume the same, would the car be more damageable and breakable than it was before, or would that depend on something else other than density?
