thank you for the calculator, very helpful

New question

, I asked this before but after researching more I ask again, what shape should I make the car? I ask this again because I made a tear drop shape for a body around the car and tested it in the wind tunnel, the drag coefficient was about 0.5, I read on other websites that it is possible to achieve CD's of as low as 0.07! so I think I could probably do a little better than 0.5 if I change the shape, I saw images of some of the lowest CD vehicles, here is one that looked interesting:

What do you guys think of this? do you think I should spend my time modelling it and trying it in the wind tunnel or do you think there are better designs?

Also the car has to have 4 wheels which may cause problems with this design.
