Abstract : The article focuses on the research on the aerodynamics of the solar vehicle Eagle Two, constructed by the
students of Lodz University of Technology for the sake of international solar car races such as Ilumen European Solar
Challenge and Bridgestone World Solar Challenge. It presents an empirical method for determination of the vehicle power
demand (due to aerodynamics and rolling friction) which allows estimation of vehicle drag coefficient. According to the
experiment the drag coefficient of Eagle Two is equal 0.23. The verification of the result was performed based on the
propulsion system efficiency. According to the manufacturer the efficiency of the electric motors is equal 88%. The authors
experimentally determined the power consumption of the vehicle. The methods allow estimation of power consumption and
demand excluding influence of the road inclination, hence the results are corresponding to the flat road testing. It was
calculated that the power demand of the Eagle Two car is 3 447 W, whereas its actual consumption is 4 032 W. The value of
the efficiency of the propulsion system obtained based on the experiment equals 85%.
