On our recent trip to California we were traveling a mix of highway speeds from 60-65 in some areas to 70-75+ in areas posted at 70. I definitely noticed that there was wind noise when we got into the 70MPH and up range. I thought it was coming from both the driver and passenger sides and wondered if it was originating around the mirrors. Otherwise the car was very quiet (and comfortable). I was discouraged by the wind noise, but the given where we live we don't go that fast unless we travel out of town and even then much of that travel isn't going to be at those speeds (although Oregon is planning to raise the speed limit in some areas). So this is going to be a fairly rare issue. When we tested a BMW X1 before buying the Q3 I noticed wind noise in the X1 even going 50 on country roads and it seemed to be coming from the front windshield/roof area. Glad we are way better than that.
