Wind resistance is often measured with sophisticated computers in multi-million dollar wind tunnels. The result is usually expressed as a number called the "drag coefficient" (Cd). While having a low drag coefficient is important, the size of the vehicle (expressed as "frontal area") is also important.

So why not calculate it yourself with a few household items and an Excel spreadsheet
