While the results are generally the most exciting aspects of an LCI study, the details of the LCI model that generates the results are equally significant; particularly when modeling the life cycle of an automobile. The modeling challenges faced in conducting the US AMP LCI of a mid-sized vehicle based on the 1995 Lumina, Intrepid and Taurus are highlighted. The number of parts (over 20,000), supply chain complexity, materials composition, and the demanding set of OEM requirements for model features required special LCI methods and solutions. The LCI model and selected results are compared with previous studies, and recommendations for improvements in the USAMP LCI model are also provided. This paper is one of six SAE publications discussing the results and execution of the USCAR AMP Generic Vehicle LCI. The papers in this series are (Overview of results 982160, 982161, 982162, 982168, 982169, 982170).

In the coming years, higher reductions in the environmental burdens of the car will be achieved through a better design of the automobile. A controversial debate continues to surround the issue of building this environmentally friendly vehicle. Car designers alike anticipate new design guidelines and evaluation tools capable of reaching these environmental goals. Life Cycle Assessment is one of the tools available today with an application to assist the automobile industry with these new design goals. The paper will demonstrate the potential benefits of LCA for the new design guidelines within the automobile industry.
