I have now test driven the Model S Performance twice and haven't been impressed with the cabin noise at freeway speeds (70-80). Once you hit 60+ I was noticing a wine from the gearbox that gets really noisy at 80 (definitely, not the invert sound). There was also a surprising amount of road noise from the wheels in the rear. About on par with my Z4, which I found noisy. Our X5 and M5 (full leather which helps) are about twice as quiet at a similar speed (and trust me the M5 has much noisier tires than the Model S).
This similar with other's experience? Has me considering the vehicle or if to plan on an audio shop adding sound dampening... Just really surprised me as if it was me I would have made sure to have "owned" quiet if producing the vehicle. At lower speeds it's amazingly quiet just by being an EV before the road noise kicks in.
