VEHICLE WEIGHT REDUCTION

The first phase of achieving lighter cars is to replace heavy materials with lighter ones, while still meeting the design intent. Traditional material substitutions implemented are stampings for castings and fabricated components; aluminium alloy castings for iron castings, and gauge reductions in stampings; substitutions by way of new high strength steels in lieu of conventional mild steels, plastics and aluminium in lieu of wood, plywood and steel have been common. Additionally vinyls for leather, abs for zinc castings in grilles, urethane for cotton paddings in seats have become commonplace. The second phase in achieving lighter cars logically calls for new design philosophy when thinking out new concepts, i.e. using one component to achieve the same function as previously done by two or three. This also has the advantage of reducing the vehicle parts count, thus reducing the investment associated in producing the product, in addition to lowering the design and engineering overheads. The third phase, in which designers, planners and engineers have the opportunity to merge all the above activities is at the conception of a new product (a new sheet of paper), when the vehicle as a whole can be downsized, which is a considerably simpler engineering exercise. A smaller car is obviously a lighter car. (TRRL)
