You can either read Phils aerodynamics seminars (first post in this forum, but I am sure you are now reading it) and choose one from pre-researched aerodynamic shapes, or choose one from already existing aerodynamic cars or velomobiles in existence (there are dedicated threads to interesting aerodynamic cars and velomobiles)

The Czech man speaks the truth. Pay heed this section here and you'll rule over the competition.
Copy what's been done before.
Keep in mind 2 very often overlooked points.
1) The air is not blowing around your vehicle.....the vehicle is moving through it. The air is just sitting there stationary and you are ramming through it with your car, the distinction has huge implications when you consider that a vehicle is adding energy to the air in order to push it out of the way, it must displace the air up and to the sides.
2) Optimal aerodynamics are achieved by using the least amount of energy to move this air out of the way, AND
Leave It As Undisturbed As Possible after you have passed through it.
Lastly, feel free to use us as a "secret weapon" there is a ton of knowledge here on ecomodder with people who would relish the chance to help guide your project to a successful conclusion. Think of us as an adviser committee. You will have to put up with some snarkiness sometimes, and you may stir up trouble when you turn members against themselves in an effort to give you the best advise, but we'll all really have fun and you'll gain a lot and learn a ton in the process.
So put up some more details about the rules you're bound to and what the cars that won in the past look like. If we see winners from the last few years we can pick them apart and figure out where the room for improvement is. There's nothing we like more here than playing the critic to somebodies work! We'll pluck em like a chicken!
Welcome!!
