All the aformentioned supercars have the engine (weight) in the back, and need large rear tires to balance the handling, not to mention to get traction at their high hp. That requires the "wrong" aero shape, but perfect aero takes a back seat to acceleration, braking and handling optimization. These cars aren't only about top speed, and they sure aren't about fuel economy. It is all a compromise for max performance. The 400mph land speed cars only need to do one thing, max top speed. They don't handle, don't brake, don't launch from a standing start.
