This is my work and it speck about CAD design and production of components in the automotive field with CFRP technology. I spoke about an electric car with solar panels. My work is an overview of the low emission technologies available today and I spoke about this technology after a personal experience with team Onda Solare. The first step of my experience started in 2018 with the collaboration in building Emilia 4, an electric and solar car vehicle that raced in the ASC2018, a race in the USA when Emilia won in cruiser category. The second step is similar to ASC but this time we competed in Australia at the BWSC, the most famous and important solar car race. The last one step of my experience temporally between the other steps, it was design a component of Emilia 4 LT(LT it is an upgrade of Emilia 4), that is the arms suspension with CAD 3D, Ansys Workbench and Solidworks. This work mixes the university skills with the new technology through CAD programming.
