Abstract： In order to design a racing car that meets the requirements of the technical regulations for lightweight events of the new energy vehicle key technical skills competition， the overall layout design of the new energy racing car is carried out in combination with the technical standards provided by the competition scheme and the body size of the racing driver. The three-dimensional design of the frame， chassis and connecting parts is carried out by using Zhongwang 3D software， the finite element analysis of each part is carried out by ANSYS software， and the lightweight design of parts is carried out according to the analysis data. On the premise of meeting the mechanical properties， safety of materials and considering the cost， light materials such as high-strength steel， aluminum alloy and carbon fiber are selected as vehicle manufacturing materials. Complete the processing， manufacturing， assembly and adjustment of the racing car according to the design drawings， and complete the road test.

Keywords： new energy racing car; lightweight; finite element analysis; assembly
