That's a good thing too, since it results in a clean break for the air as it exits the back.

There are however anomalies, such as the Lexus LS-430, which has rounded edges to the back bumper. The LS-430 has a Cd of point 25.

Someone showed these before, showing the Prius and Civic. Does anyone remember that thread?
