The objective of lightweight construction in vehicles is the reduction of vehicle mass, resulting in savings of petrol and energy and a decrease in energy-related emissions during the use phase. Life-Cycle-Analysis (LCA) of passenger cars using a strongly technical bottom-up method has revealed that the use phase may play a very important role in the complete life-cycle. However, top-down methods such as economic input-output (io) analysis are seldom adopted in investigations of aluminium lightweight applications in passenger cars and their influence on the production and use phases. The methodology adopted in this work is based on a passenger car model, and an economic io-model. The passenger car model is a basic calculation program utilising specific production- and operation-related data. The economic io-model is a static open model. It establishes the functional relationship between the final demand and production, respectively final demand and value added and may be used to calculate the direct and indirect consequences for production of a given demand. The basic assumption of this model is the linear-limitational production function with temporarily constant input coefficients. However, studies have shown that factors such as technological progress may affect input coefficients. Changes in input coefficients and io-transformation matrices may be recorded by pragmatic approaches. Four scenarios have been identified, differing in the extent to which aluminium lightweight construction is incorporated in passenger cars, over the period from 1995 to 2012.The empirical part of this work includes testing of the models, by means of a case study based on aluminium lightweight application in passenger car bodies. For the design of the aluminium specific io-model it was necessary to separate out the components of the inhomogeneous non-ferrous metal sector in order to allocate aluminium production to a self-contained sector. The same was done for the manufacture of passenger car bodies, to reveal the influence of aluminium lightweight applications. The io-model has been used to enable the analysis to include economic factors and to identify technological progress related to aluminium lightweight construction of passenger car bodies. These measures affect the input structure of the body manufacture sector, because increasing use of aluminium will result in a displacement of conventional steel manufacturing sectors. The io-analysis has been used to show how these measures affect production, structural disruption, energy and emissions. In addition the changes in energy use and emissions related to the production and use phases may be identified and compared by means of the passenger car model and the io-model. This case study of aluminium lightweight application demonstrates that the use phase is not necessarily as significant as is suggested by many other LCAs.
