Abstract Individuality and lightweight are essential strategies in the automotive industry, which have to be considered in each part of the development process [1]. For reaching the request for individuality and being efficient, the use of modular systems and product families is inevitable. Focused on the engine development this means, that the application range of an engine and the requirements for the construction increase significantly. An engine is nowadays used for several vehicle series whereby a wide performance range has to be covered as well as the materials have to be used up to their limits for reaching the lightweight targets, but not risking any damages or failures. Furthermore the engines get more complex and more powerful, which can be seen in figure 1 and figure 2. Figure 1 shows a 4-cylinder engine from the 1980s with a maximum performance of 72 kW and 230 Nm. Figure 2 shows an actual 4-cylinder engine with about 150 kW and 500 Nm. In this comparison the increasing specific power and the lightweight engineering in newer engines is well illustrated.
