Early scale model I built shows how it developed from the tear drop shape.
It is a sight to behold,not only for the great variety of ingenious cars assembled there but the night sky is so filled with stars that it takes your breath away. I did not go there to star gaze but it is quite the perk none the less.People go there to see what the flat out top speed of their car is.The horsepower required to overcome drag becomes ever so evident there.If you are in a class that does not allow body alterations to reduce drag and thus go faster,then you need to produce more and more significant amounts of horsepower to fight the wind. The research and development that went into the design of this car to be aerodynamic and thus an energy efficient vehicle would become ever so apparent when it was run flat out on the salt. Similarly, when it is compared to other less aerodynamic cars on the street, less power required for the same speed means less energy consumed.Why waste energy if you can do it with less? In the aerodynamic drag formula the velocity factor is exponential V^2, which means you multiply the CdA x V^2 x .5rho.When you take your velocity and square it and multiply that by the ever so crucial CdA you can understand why it is so important that the coefficient of drag area number be small as possible.
