Regarding the Cd, I tried for quite some time to collect data from coast down testing, and ultimately came up empty handed.
It turns out the method used to collect data, like speedometer with a camera, or hand held GPS is not accurate enough to get good coast down readings. My coast down numbers were all over the place after two years of trying.
Oh well, we gave it good shot and now know how NOT to do it.
I would think that a sample rate of let's say 10 Hz or something similar would be needed to get good coast down data, and ultimately a good Cd of the car.
