The chassis is the basic structure that contains various systems of the car and supports all parts such as the engine, transmission, brake system, body, suspension installed on it. The chassis must be safe, inexpensive and have a suitable structure and suitable chemical composition for welded joints in order to apply movable connections such as bolts on it. In addition, it is important that it is easy to produce. In this study, the selection of chassis material for the chassis design of a 3-wheel L2E class electric vehicle was studied. St52, Ck45, and C4140 steel for safety, cost, weldability and machinability factors, the technique for order preference by similarity to ideal solution (TOPSIS) and more Optimization Criterion Compromise Solution (VIKOR), multi-criteria decision making methods (CKKV) using a comparative analysis has been made. As a result of the analysis, it has been determined that the horizontal elements, vertical elements and ribs that make up the chassis will provide the most appropriate use with the specified factors and materials. As a result, producing horizontal profiles of C4140 steel and other profiles of St52 Steel was has been seen the most ideal option for both methods. The Second ideal optimization option is that horizontal profiles and federations are made of C4140 steel, and vertical profiles are preferred as St52 steel.
