I'm not sure you have a firm grasp of aerodynamics or the mechanisms that allow a car to travel at high speed. Using an available online calculator to calculate the power required to over come the aerodynamic drag which depends upon the frontal area, the coefficient of drag and the cube of the speed that the vehicle is going, therefore assuming a cd of 0.38, a frontal area of 28.2770 sq. ft, excluding the width of the mirrors, and over estimating the frontal area by 20% as the number I was always taught to use in the powertrain courses was 80% of the actuall height and width of the car, the aerodynamic power consumption alone is 590.4 horsepower at the top speed of 202 miles per hour, the rest of the power would be utilized in over coming road load forces as well as any drive line losses. Mind you its awfully hard to find better drag coefficient data so the 0.38 is based on the old GT500 and not the newer model and the dimensional analysis was also done on a 2012 gt500
