Jim,

A 20% improvement in aero drag would be great news! I need a ~17% improvement in CdA to hit lean burn at 74mph on flat land in warm weather. It would suggest a Cd reduction of about 0.04, I figure.

I think 35mph would be more accurate for a stock Insight, or around 38mph for a lightly modded one:
