"harsh" engine sound
I have just over 1100 miles on my G35 Sport. Although I have been very good about the break in period, I have now ventured a little further over the 4k mark on occasion. While the exhaust note is beautiful, there is a mechanical harshnesss coming from the engine itself. I cannot really pin it down to any one component, just an overall lack of "smoothness" It pulls great, lots of power, lots of torque, just a little noisier than I would have expected. Of course it finally has started to get a little nicer here in New York so these are my first driving days with the windows down. Anyone else experience this sensation or am I just being too critical? I appreciate your input.

I think it's perfectly normal and sounds really good. since your still in your break-in you need to give it some more time. the real engine note is between 5K and 7K... sweeeeeeeeeeeeeeeeeeeeeeeeeeet.

You should read the Car & Driver comparo with the BMW 328i...

I believe what you're hearing is something that the Car & Driver guys dislike about this car, "a lack of harmony in the engine compartment."

I have an engine/exhaust sound that I am not too sure about... usually if I hit the gas pretty hard and shoot up the RPMs and then let off of it, its a raspy (almost rattling like) sound. Sounds likes its just behind me in the center of the car?!?! Not sure what it is, any ideas?!?!
I have been meaning to get my bro in it and let him listen to it, hes ALOT more mechanically inclined than I am when it comes to engines and the like.

The article explains what I am sensing
Thanks for the link to the article. At least I know nothing is wrong and I am not imagining things. I can easily get sued to the sound eminating from the car. I have not heard any squeaks or rattles yet from the interior so I am very happy. With only 50 miles to go before break in is accomplished, I anticipate this will be a very fun weekend!!!
Thanks for the input.

OTOH, my brother just bought a Nissan Pathfinder with the VQ40xx - now that's a harsh engine.

I did feel like it was something intake/exhaust related as it seems like it happens when the car is gasping for air after punching it- that kind of what your experiencing as well?
