Interesting Thread! The vw bug has a Cd value of 0,48.A teardrop has 0,05 and an average aircraft wing profile has 0,08.The funny thing is a T2 vw bus has a cd value of 0,44 eventhough it has a larger surface area up front,it is much longer than the bug,which gives it an overall better value.
The bug´s aerodynamics are greatly improved by lowering the vehicle and adding spoilers as everyone knows.However,I haven´t seen any values to compare.
Some of the Käfer Cup bugs and a few of the hillclimb bugs have slots or holes in their fenders and some run shorter rear fenders allowing more air to pass out the back.If your racing,looks aren´t as important as function so I doubt that anyone is really going to adapt that to their street car.
