I've said nothing about wind tunnel working numbers.

Do you want this thread turned off also? When I tell you what I think about your knowledge of wind tunnels?
Well, we can now add that you don't know much about car magazines, too! Motor Trend would simply have been quoting Fiat, and Fiat would have provided the 6.3 per cent as a rounded number.

To even try to pretend that the figure was exactly 6.3 per cent, and therefore solving for the Cd of the 500 pop requires calculations to 6 decimal places, is typical of the sort of mental knots you tie yourself in when trying to prove your point. It's pretty sad.
