Motortrend it says my cars CD is 0.38 (surprise to me)
and good old untrustworthy
Wikipedia says it is 0.36. Type in 2001 Honda Civic when you search the page.
I was wrong in stating that it has the same CD as a beetle, but one guy had put a giant wing on the back of his bug and it reduced it to 0.36 (the article is amiss, sorry). The actual beetle CD is 0.48 according to Wikipedia
