I just got a loaner P85 for a day in exchange for my 60(40). One thing I noticed fairly quickly was how much quieter the P85 was. Then I narrowed it down to road noise. It seems like I start hearing the "buzz" of road noise at around 30/35mph and by about 45 or so, between the road noise and wind, I can't say that my Model S is significantly quieter than my old Lexus LS460. However, the loaner I had was almost without road noise at all until around 45, and then, all the way through 70 or so, it was significantly quieter than my old Lexus.
Was it the air suspension? Does anyone know enough about the air suspension to say whether than could isolate road noise from the chasis? Maybe tires? Maybe just a newer car with slightly "tighter" construction?
P.S. The motor "whine" was significantly louder both when I floored it and just in general.
P.P.S. The P85 is CRAZY fast, but I really had to search to find places where I could floor it with any safety at all.
