Drag Coefficient Numbers for All MN12/FN10's?

I was wondering if anyone has a break down of the drag coefficient numbers for all the MN12/FN10 cars and how they differ from the year to year changes. Not that the shape of the cars changed much over their production run, but I wonder how something like the 96 MN12 and 97 FN10 facelifts affected the numbers.

Don't know the numbers... But I do remember reading that when the 89 SC came out the only thing "slipperier" at the time was the 89 Corvette. Again, just something lurking in the back of my mind... I might be wrong.

Around 700 hours of Wind tunnel testing went into the 1989 Thunderbird design with a 0.31 Drag coefficient.

There's a good link to see where it stacks up against other production and concept cars. Our T-Birds (no mention of MN-12, FN-10, Cougars, or Mk VIIIs) are towards the top of the center column, and the total drag area is 6.63 ft². Those numbers are specifically from the '89 Thunderbird, but I have no clue if further wind tunnel testing was done on later models.

Its better than most newer cars, very, very aerodynamic.

Its more aerodynamic than the Veyron.

I wonder what the Cougars and Mark's respective numbers are, too bad I can't seem to find them anywhere. I know that 87 Cougars had a drag coefficient of .36 but of course that was an entirely different platform.

Plus I always thought the smoothed out corners of the 96-97 MN12's might have improved the cars aerodynamics, but looks can be deceiving when it comes to drag coefficient.


EDIT: Well I seem to be finding a Drag coefficient of 0.330 for the Marks, but nothing for the Cougars.

This is the oldest necrothread I've ever posted to that I can recall but I wanted to add something that took me a little while to find.

i was tweaking my quarterhorse settings so I was looking for data on the tbird's frontal area (in sqft) in addition to the coefficient of drag. This number was fairly hard to find.
I suppose BE uses this to calculate ET times after analyzing the HP.

Make Model Year Cd Height (In) Width (In) Frontal Area (ft^2) CdA
Ford Thunderbird 1989 - 1997 0.31 52.8 72.0 22.2 6.87

I'm going to say that 22.2 sqft is "close enough" for my needs. If you need a more accurate number, measure it yourself....
