I also put closed-tube manometers (made from aquarium hose) at different
points around the car and tried *that*. The car was an aerodynamic mess.


Erm, you mean to tell us that you couldn't discern that just from
lookin' at it? Or were you just young(ish), full of testosterone, and
had far too much time on your hands? Methinks it's the latter.


No, I'm not good at judging Cd (coefficient of drag) just by looking at a
car. Let's see how good you are. g The Cd of a Hummer H2 is 0.57. Without
looking it up, what do you estimate is the Cd for a Lotus 7? How about a
1992 Ford Crown Victoria? BTW, the Fiesta is alleged to be 0.41.

(I picked up the data from a Wikipedia source, and I haven't been successful
in tracking it back to the real origin, but it may be from coasting-test
data, or "rolldown" data as some people call it.)
