I would third this. I have driven the car for about a month with several highway trips (speeds from 60-85 MPH) with no major noise. Granted it is not a big benz but compared to other cars we have had, not out of the ordinary. And honestly, it is actually quieter than the other cars.
Agreed. And when compared to a smaller Benzs like the current generation C-class or E-class , the GT on 19's is just as quiet at highway speeds of 65-85mph.
Beg your pardon, but this is false. Currently only some GM, Acura, and Infiniti vehicles have the Bose noise cancelling tech. I assume you are referring to the recent Bose partnership with NXP, which will supposedly bring noise cancelling to all vehicles with a Bose headunit and the SAF775x chip. For right now, however, the CX-5 has no such noise cancelling technology, and I'm not even certain whether our Bose carries the SAF775x chip. Even if it does become available, you have to find someone willing and capable to enable it, which could be a whole other (expensive) headache. Maybe in the future, though! It would definitely be neat.
What Bose-equipped CX-5's do have is this (which might be helpful):
AudioPilot 2*4
AudioPilot 2 automatically adjusts audio
volume and sound quality in accordance
with the level of noise entering the vehicle
interior while driving. When AudioPilot
2 is turned on, the system automatically
calculates the conditions for optimum
hearing of sound which may be difficult
to hear depending on exterior noise.
AudioPilot 2 can be set on or off.

True. Having owned four Mazdas now, however, my personal opinion is that ALC/Audiopilot is more annoying than helpful. It tends to overcompensate despite how sensitive a setting the driver uses. Again, you might have a different experience.
Since the topic is road noise, I've experienced low levels of perceived road noise in my Bose-equipped GT.
What are your observations on road noise in your GT?
Take a look at this entry from 3/25/2012 on this topic :

I looked at Inodes references at the time and remember that on the Bose referenced pages it said "Noise Cancelation Teck."
http://worldwide.bose.com/axa/en/web/popup_automotive_audiopilot/page.html
Today I read that it says "Noise Compensation Teck."
Either Inodes and I both read it wrong almost two years ago or they changed the website to be more accurate which is what I believe must have happened. It should also help them sell the new chip... In any case there is some teck. in the Bose equipped CX-5 systems that is suppose to reduce the impact of background noise to your ear when music is being played....
I drove a CX-5 for the first time Monday, a test drive at the dealer. It was a 2014 Sport MT-6, the lowest trim level. My main goal was a comparison test with my 2006 Escape XLS MT-5. The most notable difference was the Mazda's quietness relative to the Escape. Mind you, my Escape is the quietest it has been during the 7 years I've owned it due to the tires (Destination LE2). The Michelin LTX MS tires it wore before were long lasting, but always noisy. The point is, while my Escape has been comfortably quiet since buying the LE2's 30K ago, I look forward owning the much quieter Mazda.
I dont know how you guys think the CX5 is quiet, you must be comparing them to some very noisy automobiles or you dont listen much to the radio on the highway. I have been doing some testing because the perceived noise level at first when driving the CX5 at 65+ mph on the highway is that it is ok. As soon as you try to listen to the radio though forget it. You have to turn the radio up to uncomfortable levels to make out the vocals and the bass is just about wiped out by the engine and road noise. This for me has been frustrating. I acquired a decent radio shack SPL meter that is more accurate than the phone app I had been using. That meter has a weighting option that allows you to change the frequency of the readings. On the default setting the frequency range is 32 htz-10,000 Hz. With the other setting the frequency range is 500 hrz-10,000 Hz or what they say is the range in which the human ear is most sensitive. My readings with the 500-10k setting are very good at around 68 db on the highway doing 70 mph. That is considered luxury car level but this belies the truth about the CX5. When I set the SPL meter to the 32-10k setting the reading goes up to a whopping 85 db. Most of this lower frequency noise is coming from the engine compartment (no surprise), which I suspect is from the fact that there is almost no insulation on the firewall. Couple this with the high noise of direct injection and the fact that the motor mounts work harder with a direct clutch connecting the engine to the transmission and you have big low frequency noise levels in the cabin. In fact I can feel the vibration in the floor boards and on the interior panels. Unfortunately there is very little I can do here. I could install more sound deadener on the firewall and front floor board but I think that will only reduce the upper frequency noise or resonating panels. I could install mass loaded vinyl if I wanted to rip out my interior but for me thats just crazy. I'm hoping that when these tires wear out that installing a quieter tire will help as I think much of it is from the tires.
I dont think there is anything wrong with my CX5 either because this is my second CX5 and its actually quieter than my 2013 I had with the noisier 2.0 engine. I'm also comparing noise levels to my previous automobile, which was a 2001 Toyota Tundra V8. In fact I remember a heavy vinyl like firewall insulation covering on that trucks firewall and I wonder if it was some kind of MLV. I had no idea just how quiet that truck was until long after I bought my Mazda. I could listen to music all day long on my highway commutes and hardly had to turn up the volume at all. O-well, lesson learned! If I didnt do so much highway driving I probably wouldnt even notice how loud this SUV is but I do some long commutes and it gets tiring after a while.

I have a 2014 CX-5 GT AWD, it is noisy I'm planning to install some noise dampening material sooner or later.
It actually sound louder on highways (lot of road noise and some wind noise) than my old 2007 Elantra. I understand the wind noise is from the shape of the CUV, but road noise I think is a bit excessive.

To reduce road noise I used Second Skin..Luxury Liner Pro. Pull back the front carpet and cut pieces to cover the metal. Take up the sytrofoam & place pieces under it, but allow space for it to go back in place. I can promise you this WILL reduce road noise. My first was having Lizard Skin sound deadening coating sprayed in wheel well and under floor pan. That is a good first step, but the most notable sound dampening occured when used Luxury Liner Pro. It is easy to cut with a knife. I put mine in place and didn't glue it, not necessary. It is heavy enough to stay in place without gluing. I have WORKED for 6 months since I got my car on sound dampening. Also, Micelin Latitude Tours help as well.
So you basically put mass loaded vinyl only under the front floor boards with about the same square footage as a floor mat? Besides subjective measurements do you have anything imperial to go by?

Put mass loaded vinyl combined with acoustical foam. the Luxury Liner Pro is the two bound to one another.
Square footage wise, a little less than the floor mats, but that would be a close estimate.

Road Noise: This thread is hilarious. Every luxury brand car I've had has been quieter at highway speeds than the CX-5. I'm not talking about tire noise. The CX-5 has a tolerable, but noticeable amount of wind noise at highway speeds. Every vehicle compared on this thread has been old and/or a "regular" brand. Of course a new CX-5 is going to be quieter than a 2000 something that cost $15k new.
Make it quieter: Being a regular user of acoustical products on auto and home, there are many solutions out there to reduce cabin noise. Other than quiet tires (reviews usually tell you) you can add lining to the floor and doors to deaden sound. There is even spray that can line wheel wells to reduce road noise a bit more. Usually the products are inexpensive but labor can be expensive depending how far you want to go.
