Aerodynamic Cars

Is a car with smooth sides the most aerodynamic it could be?

A golf ball has dimples for a reason. They already tried smooth spheres, but the ones with dimples floated longer and went farther more easily. [http://www.livescience.com/32446-why-do-golf-balls-have-dimples.html]

The newest track suits (I read about this at least a year ago) also have small dimples on it rather than being perfectly smooth in order to shave a few hundredths of a second off. [http://www.gizmag.com/nike-pro-turbospeed-golf-ball-track-uniform/22520/]

Update: I just did a search for "cars with dimples" and found that MythBusters already did this. Mythbuster results showed a 11% increase in MPG (miles per gallon). =D
