I agree, it feels like the engine is going to slap me in the face past 6500 rpm. I think the reviewers were well in line when they complained about the harshness, picky or not. Lets me honest here. Love the car BIGTIME, but it is harsh.

lolll :rofl2:

We aren't talking so much about sound here, its more the vibration at high RPM that bothers some of us I think. Just because its a sports car, it doesnt mean it should feel so coarse and out of control at high RPM. We go back to the same point over and over... and the fact of the matter is that an engine that is made to rev high and for sport driving should be MORE well balanced and exhibit LESS vibration. The engine internals are put through so much more stress, being a sports car and all, that it should be a LOT smoother to aid in its longevity.

Does that make sense to anyone else or is it just me being crazy?

I c wat u r saying and u do have a point. But one thing u first year buyers don't realize is.
Though the vq 37 is proven in the G37. Its still mated to a seperately programmed ECU,
New suspension and other components. So these parts are tested in pre production
But production brings forth new issues that must be resolved from the line up.
But guess who are the final testers??? First year buyers.
Cars like this are usually better bought the 1st year by serious tuners or people that don't drive fast but wanna sports car for show.
Reason being tuners will observe problems but they don't care too much cuz they are always trying to make the car better than production. And. Mild drivers. Well. They never put hard enough work in sports cars that they don't need max performance.
But in betweeners. Meaning, you might track here and there. Have a spirited driving style
And will use this car as a daily but. Won't go past suspension n bolt ons. Don't wanna void warranty. Will not do or are interested in tranny tuning or aspirating the engine.
I would suggest. WAIT FOR THE 2ND YEAR MODEL.
AND EVEN THEN. WAIT TILL UR TRUSTED MAGAZINE GIVES REPORT.
Its very common for 1st year cars to exhibit crudeness or harshness. 2nd n 3rd year cars are vastly improved. And the 4th year refresh is usually the sweetest.
I know some of you couldn't wait to get one and an extra year is long.
But tuners report back to companies n companies make fixes.
Novice racers win in year 2.
