I found this web site - http://www.edmunds.com/advice/specialreports/articles/106954/article.html
"For a full-size truck, a change in drag coefficient of 0.01 is approximately equal to an improvement in fuel economy of 0.1 mpg on the combined city/highway driving cycle," says GM's Schenkel. "The same drag coefficient reduction can improve a car's fuel economy by approximately 0.2 mpg."
Interesting .. a reduction of a cars drag co-ef of 0.01 = +0.2Mpg
