" As a facet of Ford’s Project Alpha, Kopka, head of Ford’s design department, reasoned that a design based upon serious aerodynamic science was an attainable solution to the fuel economy issue. At that time, there was a considerable bugaboo regarding aerodynamics in automobile design. It was argued that cars would all look like jelly beans and all look alike. Kopka believed there was considerable room for implementing advanced aerodynamics without sacrificing style and individuality.

Probe I was considerably more immune to the fluctuations of the petroleum market. Its sleek and angular aerodynamic shape achieved a drag coefficient in the wind tunnel of 0.22, some 37 percent less than the 0.40 then typical for a two-door, four-passenger coupe. Its use of the newly developed W Code Mustang Cobra engine was able to double the average fuel economy of the conventional 2 +2 sports sedan without sacrificing horsepower. "

I'm curious what my Probe's Cd is... it must be damn close to .22

I thought i read the first probe concept was .24-5, but .22 is not far off. I think that picture is fake.

I'm sure it is pretty close to that now. :thumbup:
Stock the 1st generation Probe GL had a .33 Cd .

curious
 

With 'before' and 'after' constant-speed highway mpg we should be able to 'guestimate' the new Cd.

first Probe
 

The first Probe was Cd 0.25 according to Ford.
I believe the Probe-III was reported at Cd 0.22.
