The body's drag coefficient is constant between 20-mph and 250-mph.Above that,compressability effects begin to come into play as shockwave-dependent transonic flow begins to initiate.
The length of the body is a function of height and all proportions remain the same.(just as if you put it in a copy machine and enlarged or shrunk it)
You could 'stretch' the body simply by adding to the very center,and pay for the added skin friction,as limousines are done.
