In the aero-mod sticky or aero seminar sticky there are some values from SAE research investigations on wind effects which have been published by the EPA.
In the book 'More with Less' there is a discussion about the GM/AeroVironment strategy for wind during the International Solar Challenge back in 1987.
Low power vehicles will suffer greater losses in wind.
I just recently got 47.9 mpg at 65 mph with the 4,800-lb T-100/trailer combo in a 26-mph tailwind in Colorado.About 22.9 mpg better than its baseline for the 'naked' truck.
My CRX could see a 50% reduction in hwy mpg based on wind conditions.
Things might need to be taken on a case-specific basis regarding this topic.
