Abstract
Due to environmental and commercial reasons, automakers have been looking for ways to reduce the amount of energy their cars consume throughout their life cycle. In addition, the industry has been obliged to comply with increasingly stringent and restrictive rules on vehicular emissions. Thus, there has been great focus on reducing the weight of vehicles. There are many ways to achieve the goals of weight reduction, whether by focusing on vehicles Body in White (BIW), automotive glazing, among others. This paper will describe the methodology implemented in Betim-MG plant of Fiat Chrysler Automobiles (FCA) to reduce the weight of automotive hoods. Initially it used an evaluate-andcompare procedure to identify the current status of FCA vehicles against their competition in terms of material usage efficiency. Then, a DFSS Project was launched to develop a new lightweight hood concept that could be used in future FCA LATAM based vehicles. Through the use of the DFSS methodology, a complete set of tests and functional requirements was defined. It intends to serve as a basis for designing the automotive hood in a way that can guarantee not only the weight saving but also the high quality of the product.
