It took me a while to figure out that graph. Soooo...
Since my Insight is an aerodynamically shaped hatchback I use curve "a".
If my diffuser has a slope of 7.5° compared to the previous section's slope, the diffuser would have zero effect on overall Cd. If the slope is 10° different, Cd goes up by about .008. Whew.
Is that right?
