The Nissan 370Z fits the definition of a true GT (Gran Turismo), a high performance vehicle designed for high speed, long distance travel in comfort and style. I love my Z but find that the road noise really takes away from the comfort of mid to long cruises. You cannot even hold a conversation with a passenger at 70 MPH with the stereo off and windows up with raising your voice considerably and the excessive noise takes a lot away from the enjoyment of music regardless of how loud it is. Yes, I know it's a sports car, I've owned many. I like a good exhaust note and engine growl when pushing it, but when at speed and in 6th gear there is no excuse for the car to be as loud as it is. Nissan dropped the ball on the design. I'm also convinced that the majority of the noise is tire related, as soon as I hit a smooth patch of non-grooved asphalt on the freeway the sound drops at least 10 db.
Tire noise levels will be a major factor when it comes time to replace the OEM's.
