Of note would be how that the barn door flat front end of the car has even less of a radii than the white Camaro, no 'moonies' for the deeply inset wheels, and ( rear ) tires which stick out directly into the airflow. As shown in this image, the Cd was .292
Reading over this thread, I have to apologize for misspelling " Cd " as .Cd - as was pointed out to me, there is not period before "Cd".
I'm learning.
I also found this image interesting. The windshield is near vertical, yet there is attached flow along the roof. I guess this is a good example of how little curvature is needed to retain the airflow.

in one of my SAE papers,the researchers found that for their passenger car,a 40-mm radius was all that was necessary to achieve attached flow at the leading edges.That's not to say that it's the lowest drag radius,just that there's no separation.
