Abstract: The performance characteristics and fuel economy of a vehicle depends on chassis parameters such as its shape, dimension and design parameters, kerb weight, engine specifications etc. thereby having implications on its energy consumption. A comparative study to analyse the impact of chassis on different cars using IPG Carmaker software is conducted. In order to accomplish this, cars from four categories namely: Sports Utility Vehicle (SUV),Multi-Utility Vehicle (MUV), Hatchback and Sedan were selected in such a way that they have a similar engine displacement to ensure that the driving conditions are similar, the New European Driving cycle (NEDC) was taken as the testing standard. A Performance-Size-Fuel economy Index (PSFI) is used to quantify the extent to which technical efficiency gains have been achieved in an automobile. Upon simulation, obtained results show that the PSFI value for a car in the Sports Utility Vehicle category is nearly 29 percent lower than for a car in the Sedan category. This difference is mainly attributed to the chassis parameters which in turn influence the braking and acceleration performance as well as the fuel economy of the vehicle.
