Objective analysis of cabin noise solutions

onzedge

I have no idea why the Z is getting this bad rap -- seriously. I read what people say on the forum about the noise. I also read reviews that state the same complaint and I still don't get it. I never thought this Z was noisy (or at least noisy in a negative way) until I started reading all this stuff.

Now I am often distracted when I drive because I am trying to figure out if the car is "noisy" or not. Geez, like I need something else to f**king obsess about. Honestly, my obsessions list is long. Everyone who rides with me agree that the car is not very noisy inside. People form my wife to colleagues who happpen to tag along with me all agree that the ride is smooth. These people drive "normal" cars, too.

Sure, under hard acceleration it gets somewhat loud (intake and exhaust help that), but it is the good loud. It is the sweet song sung by a fairly high performing engine that is allowed to breathe correctly. But when cruising it is not at all uncomfortable. I have 13,500 miles so far which include 4 road trips of 800 miles each (driven at 80 – 85 mph).

Is it a fluke? Am I going deaf? Are people expecting too much? I have no clue. I do know though that the Z is, like others have said, a sports car. So go ahead and muck it up with your insulation and decible meters and such. Whatever people do to make them happy in their rides, as long as they are not hurting others, is OK, I guess.

Point well made. Just the other day i had a friend who has driven nothing
but high end luxury cars ride with me and his first comment was "hey this rides and sounds a lot better than i thought it would".

*sigh*

What a bunch of idiots on this board.

Every review of the 370Z complains about the noise - what do you think that does to people's opinions considering buying the car?

I owned an MR-2 SC and an NSX - the 370Z noise is worse than both, though not necessarily louder than my HKS Stage II MR-2, just much more annoying.

all this talk about noise is giving the 370 a bad rap to people thinking about buying the car. to those complaining did you even take a test drive and if you did stop crying about the road noise. it is not that bad.

^ This!

I myself noticed no unnecessary noise during my test drive; I was allowed to take it on the freeway as well; the ride is very smooth & I was actually amazed how quiet it was compared to my integra

I think it's part of the raw character of the car. I enjoy hearing the tiny pebbles/sand/water under the tires, I enjoy the limited visibility (in a way), I enjoy that I can hear the clutch when I depress the pedal prior to starting the car. I even smile when I open the hood for cleaning and have to use a prop rod like an old muscle car.

These are some of the reasons I bought the 370Z over something similarly priced but quiet/refined/boring, like a G37 or IS350.

Buy a better stereo, put on some good music and try a smile once in a while that you own a Z.
