I was doing a little research on Cd, scale, models and Reynolds numbers and found this paper.

This is curious, the "Estate Back" (think of a Chrysler 300 wagon) has a higher Cd than the "Fastback".

Based on doing many many template overlays and just eyeballing it, I'd have to say the Estate Back fits the template, and the fastback falls short.

What's going on here?
