"I know some larger GM cars had them in the 90s...but they didn't open."
 
Yeah, I've wondered about the purpose of those vent windows that didn't open, but I don't know why some GM cars featured these.

"Hey, how COULD we calculate it?"
 
I think it would be very difficult to calculate it, considering all the variables. For example, open vent windows increase air drag slightly, and the exact amount of draf depends on the car's design, how much, how frequently and how long the vents are open, and more. Also, average speed varies all over the place, depending on traffic, speed limits, roads and terrain, enforcement, etc.

Maybe it was some kind of internal sabotage to make people hate GM cars a little more ...of course, the cheapo interiors and wheezy powertrains of that era could do the job by themselves. But they got good mileage, so I guess someone will like them.
 
I drove my old car which has wing windows, today. They don't seem to make any wind noise until highway speeds are reached - but this is a nearly 50 year old car with original weatherstripping, so I can't hold that against it. I do remember the passenger side one would leak in the rain, too.
 
That car has such superior ventilation to modern cars. In a modern car, I have to turn the fan on to the lowest or second lowest setting to be comfortable - I can't stand to have it off. In the old car, I can just open the fresh air intake, or maybe crack a wing window if it is stuffy, and everything is good.

My 2002 is very similar. The vent windows compensate for a true integrated fresh air ventilation system.
