The automotive industry is facing unprecedented pressure to reduce costs without compromising on quality and performance, particularly in the design and manufacturing. This paper provides a technical review of the multifaceted challenges involved in achieving cost efficiency while maintaining financial viability, functional integrity, and market competitiveness. Financial viability stands as a primary obstacle in cost reduction projects. The demand for innovative products needs to be balanced with the need for affordable materials while maintaining structural integrity. Suppliers’ cost structures, raw material fluctuations, and production volumes must be considered on the way to obtain optimal costs. Functional aspects lead to another layer of complexity, once changes in design or materials should not compromise safety, durability, or performance. Rigorous testing and simulation tools are indispensable to validate changes in the manufacturing process. Marketing considerations are also significant to the success of cost reduction strategies. Brand reputation and customer perceptions of quality must be safeguarded when changes are implemented. To that end, communication strategies to convey the benefits of cost reduction without compromising perceived value are a key factor to enhance market acceptance. Another crucial element in the execution of cost reduction projects is operational efficiency. Streamlining production processes, optimizing supply chain logistics, and embracing automation technologies require careful planning and implementation to avoid disruptions in production schedules. In conclusion, addressing the challenges of reducing costs in automotive body exterior parts demands a holistic approach that considers financial, functional, and marketing aspects. Striking the right balance between these elements is essential for the success of cost reduction initiatives, ensuring that the automotive industry remains competitive while meeting the demands of a cost-conscious market. A solid technical background for all the parties involved is imperative, and this text provides an overview of the pivotal topics in that context.
