engine harshness at high revs

I agree. I guess if you have driven many great sports cars, it could bother you a little bit. Some of those reviewers are way too picky - many complained about noise from the wheel wells, and a rough ride, but the 370z had a softer, quieter ride than my Saan 9-3!

Can't take it too personally, with a car as great as the Z, they really have to dig to come up with "cons"

I too like the high-rpm coarseness on the 370Z. Most people that have ridden in the car like it as well. For me, it seems that once you get over 6500rpms is when engine noise is rather intrusive. I don't know, but it would stand to reason that this is partly due to the VVEL. If you think about it, valve lift/duration increases with revs, so essentially, the VVEL allows more and more air/fuel into the engine the higher you rev it, so it would only make sense that more power = more noise.

Either way, it almost has a different character in the high rpms/sounds like a different engine.

The one thing that DID surprise me about the powertrain is how much it sounds like a 4-banger. LOL. The engine just doesn't have the typical V6 smoothness that I was use to from my 2007 Altima 3.5SE. That's comparing apples to oranges, but you'd still expect a slight resemblance considering they're both Nissan V6's. But not so much.

Late,

I don't know about everything else, but I can agree with that.
