In order to find out the effects of vehicle dynamic performance and fuel economy caused by changing the vehicle parameter which includes vehicle quality (m), air resistance coefficient (CD), and the main reducer gear ratio (i0), the essay conducts a simulation model based on Cruise software, and processes dates according orthogonal experiment principle, finally find out the primary and secondary one, in addition the optimal combination. The result indicates that air resistance coefficient plays a crucial role in improving vehicle dynamic performance while vehicle quality plays a key role on vehicle fuel economy. Which in accordance with the theoretical research results. Therefore a reference is provided in the future reach on design and optimization vehicle dynamic performance and fuel economy.
