Stylistic design engineering (SDE) to realize a new concept of classic car

In the present work the Stylistic Design Engineering (SDE), a structured engineering methodology developed to carry out car design projects, is applied to the creation of a new reliable and robust utility vehicle, also suitable for traveling in the countryside. In particular, the design project aimed at the possibility of launching a new Citroen 2CV that would maintain the lightness and reduced fuel consumption of the previous model but that would combine these characteristics with greater eco-sustainability, thanks to electric drive, and greater comfort for passengers. SDE consists of the following steps: (1) sketches; (2) 2D CAD drawings; (3) 3D CAD models; (4) 3D printed models (also referred to as styling models); (5) Optimization of maquettes through technical objectives. This project deals with the exterior restyling of the Citroen 2CV and was carried out using different technologies and design methodologies that will be further explained in detail, such as the Pininfarina method, the QFD (Quality Function Deployment) and the 6 Sigma method. The work was organized in different phases and in all these phases the quality methodologies mentioned above were used. At first the Citroen style was studied, a fundamental step to better understand the characteristics of the brand and also the main characteristics carried out over the years of the product's life. Subsequently, the freehand sketching phase was carried out, inspired by the considerations made in the previous study phase. This phase continued until a satisfactory form was found by analyzing and discarding the various proposals of the various types of style. Once the definitive proposal was chosen, the definitive three-dimensional shape was obtained and on it it was possible to evaluate proportions and dimensions, also thanks to the rendering software.
