The results outlined above highlight the innovation of the steel and forging industry. Assessing material, design and forging innovations demonstrates that a significant weight reduction of 42 kg appears possible on the vehicle analysed. Secondary lightweight design potential has not yet been taken into account. With respect to the lightweight design potential, the areas of powertrain and chassis are of equal importance as the car body. Steel materials and forging technology may be used to achieve lightweight design, with the cost per kilogram lightweight design lying below that incurred for many new types of manufacturing technologies. Some lightweight design potential even promises cost neutrality. This lightweight design thus has a broad impact and can contribute significantly to reducing the total CO2 emissions. To utilize these lightweight design ideas, it is necessary to include material and forging potential in the early phases of system and part development. Here, there are tried-and-tested simultaneous engineering processes. However, these need to be used for considerably more components than is currently the case. The purchasing process should begin during earlier phases of development, namely when the lightweight design proposals of the supplier can still flow from material or production engineering into part design. The Lightweight Forging Initiative has determined that not only is there potential to be tapped, but also that there is a need for research. For example, the correlation between the cleanliness of the steel and the fatigue strength needs to be better quantified even for applications beyond anti-friction bearings in order to transfer new steel manufacturing technologies into lightweight design potential. To address these and other issues, a lead technology project is being applied for at the AiF (an alliance of research associations). Currently (Nov. 2013), this project is in the assessment phase. Future activities of The Lightweight Forging Initiative will include communication of the results within the industry, partly by means of a conference event at the end of 2014. Furthermore, discussions will be held on continuing the successful and cooperative collaboration on a different vehicle class, or on raising collaboration to a global level.
