Photos of e30 in a wind tunnel?

[JiXer]

Anybody ever see any? Been searching and can't find it.
Super curious about the aero on our cars.

They are a brick. There, everything you needed to know.

Yeah. I know its no f1 car, but thats precisely why I want to know more about it.
Someone once said that they were slow too and sat too high. That didn't deter us from building motors, adding turbos and lowering the cars.

I've never seen anything released by BMW.

And if they did, would you know how to make heads or tails of it based on a picture?

not but based on that pic it looks pretty aerodynamic

Looks can be very deceiving on aerodynamics.

E30's are pretty aerodynamic. Exceeding many Ferrari's.

The .32 mentioned above is right, or darn close.
A Ferrari testarosa is .33 if I remember corectly.
Toyota Prius has a .26, but its very well done.


1989 325IS
drag - .33
Frontal area - 20.9 sq. foot

1990 325 Vet'
Drag - .45
Frontal - 20.9

1990 Ferrari Testarosa
Drag - .36
Area - 13.37

1990 Vette' The kicker....
Drag - .341
frontal -19.28


As quoted from the Road&Track Feb 1988 Comparison Test of '88 M3 and '87 325is:
"Despite, or perhaps better said, BECAUSE OF all the add-ons, BMW claims a Cx of 0.33 versus 0.39 of the 325is."

Keep in mind this is for the '87 325is, which is more of a brick than the '88-'90 325is and the '91 325i with a Sports Package. Those cars, and the '91 318is which has the exact same exterior package, are running a Cx of 0.35 from what I have found on e30 318is sites.

So, it breaks down like this:

'87 325is - .39
'88<325is - .35
'88-90 M3 - .33

I can google all by myself :)
Wasn't looking for numbers. I'm looking for photos.
And there is plenty that can be inferred from the photos, such as where to place hood vents, wings, etc. which essentially what I am looking for.

tape little pieces of yard on your car every 5 inches in every direction and go out on the highway. Drive at a consistent speed away from other cars and have someone in an other car video you and what the yarn is doing.

Yes I am serious. If you are really that curious on what to do to the e30 aero wise.

[ben312]

wait, so you asked for pics then posted some then asked for more or whats going on?

[e34john]

the picture he posted is an example of what hes looking for
