I have recently changed from an Audi Q3 s line diesel for my lexus. Must say the Lexus is quieter than the Audi and more comfortable and I have had several over the last 10yrs. I have not noticed any excessive wind noise. So far I have found it at least comparative to the Audi and is certainly more economical on short journeys. Granted the speed of the Lexus is different but I was aware of this prior to purchase. I can honestly say that apart from the navigation premium I am not disappointed.
