Drag values for familiar objects

These Cd's and Areas let you calculate the drag for a particular car and they should help give you an idea of what shapes carry what penalties. You might also use this table to help choose a donor car.

To get the total drag effect, you have to scale (multiply) this by the size, in square feet. I neglected to include the areas in this first pass and will have to revisit this table. Some of the following came from the Wiki, Drag Coefficient.

CdA values from Wiki's "Automotive aerodynamics".
