Wind Noise from Both Rear Windows 1/2 Down
Has anyone noticed the amount of wind noise @ 55mph or above when you have both rear door windows about 1/2 way down.
In my 2015 GS 350 it is extremely annoying.
I drive with my windows down a lot and I have never had this on any previous car.
Just wondering if it is all of the GS 350's or possibly is it an areo issue with my car.

Haven't tried that with my GS, but my general experience with sedans is the side window buffeting is terrible with only the back windows open. As ChronoR mentioned, you can modulate the resonance by adjusting how far open they are and which windows are open.

Give it a try the next time you get a chance.
It is as shurik74 says, Like a Helicopter Blades beating down on you.
It consumes my attention, it's not like a wind noise that you can't hear what others are saying. Try it.
sarmyth, I'll try the sunroof and see if it changes. Thanks

The buffeting wind noise is normal for pretty much any car. You can read about the science of it here http://jalopnik.com/why-do-slightly-...oun-1447498738

This is particularly pertinent:
If it didn't happen in your old car, it's because it was less aerodynamic!
It's more noticeable in modern cars because they're more aerodynamic. By trying to improve gas mileage as much as possible, car manufacturers are creating cars that have much smoother air flows over the windows. My 2007 Fit has side window buffeting like crazy, but my old 1966 Fairlane never did. In my Fit, like in a lot of cars, it only really happens with the back window. I've not worked through all of the math, but my instinct is that it's because the air flow doesn't hug the car as closely and isn't as smooth over the front windows. As the air passes over the front of the car, it spreads out a bit before coming back and hugging the car sides closely near the back window.
