    CO2 emission targets became a crucial obstacle for vehicle producers. In order to overcome this problem, weight reduction potentials are getting more and more critical. In this study, for a light commercial vehicle, a glass fiber reinforced thermoplastic front-end structure has been analyzed. At first, a fully plastic draft design is analyzed and compared with the current metal structure. After that, a topology volume is extracted from the existing vehicle structure, and topology optimizations have been carried out according to the modal and static loading performance targets. Different optimization parameters have been investigated to decide the best solution in terms of performance and weight. Load paths and optimum design are calculated by topology results. Due to the packaging problems with the radiator and headlamp, optimization volume is modified, and the new topology volume and optimizations are completed. Based on the topology results, a feasible design is prepared, and detailed non-linear analyses are started. After the non-linear analyses, free size optimization is applied to the ribs of the part. In this study, a feasible preliminary design at the same performance with less weight respect to the current metal version is completed.
