There are many type of steering system exist nowadays. However, the main focus of this paper is to study on the Semi-active steering (SAS). This project deals with the effect of using SAS in combination with the flat chassis. One of main concern for using a conventional steering method is the lack of backup steering system. The recently developed steer-by-wire (SBW) system does have a backup system. However, the difference between SAS and SBW is in the usage of a flexible shaft in the SAS system, while SBW uses a rigid shaft. This, combine with flat chassis with all in-wheel motor configuration provide a new and simpler package of car. This paper will collect the data and analyse the effect of SAS on flat chassis vehicle. The result will then be compared with the conventional system currently used
