I think you guys are off your rocker if you think Infiniti engineers is sitting around worrying about the .6 second advantage the 3 series has over the G. Infiniti will continue to offer the best all around vehicle at a competitive price and the 4,000+ sales a month means they are doing a good job. That does not involve winning 0-60second battles.
A G37 sedan should be faster than the G35 sedan but there is no guarantee it will end up being faster than 3 series. Weight is still a factor and the 3.7 is heavier.

Seeing that the G35 sedan weighs in at 3,600lb and the G37 coupe at a boggling 3,800lbs, it's no wonder the G35 sedan posts equal or better times than the more powerful G37 coupe. Throw the VQ37 into the sedan and it's going to flat out smoke the G37 coupe. The VQ37HR hardly weighs anymore than the VQ35HR. You're talking 200cc's of extra displacement. I think the weight difference between the two is like 5lb or 6lbs. Why would Infiniti intentionally add weight to the sedan if they didn't need to? If the VQ37 makes it into the sedan, I'm getting one....eventually 
The G35 sedans are currently posting 13.8-13.9@102mph on street tires. There's no doubt in my mind a G37 sedan will do 13.5-13.6s@104mph on street tires and 13.2-13.3 on DRs. That's more than competitive with stock 335i's. Now if the 335 adds a chip, then all bets are off.

edit sentr 2.0/2.5
altima 2.5/3.5
maxima 2.5/3.5

I then said a heavier G37 sedan would likely have minimal improvement in performance. This is evident in the fact that the heavier G37 coupe has virtually identical acceleration to the 07+ G35 sedan.
At this point, there is no objective test that indicates a G37 sedan would be .5 sec quicker from 0-60 and in the 1/4 mile than a G35 sedan. In fact, it's highly unlikely a G37 sedan would go from a 13.8-14.1 sec 1/4 mile car to a 13.3-13.6 sec 1/4 mile car with only 30 extra horses even if the weight was kept exactly the same.
If you're comparing your 1st gen G35 to the G37, there's more than a 30 hp difference in power because the G37's 330 hp rating is based on the more conservative SAE net rev 8/04 rating whereas the G35 coupe's 298 hp is based on the old rating method. Thus, the actual difference in power between your G35 and the G37 is likely over 40+ hp. That, and the fact that the VQHR motor has been heavily revised with a wider powerband and higher redline is why the G37 is a good 1/2 sec quicker 0-60 and in the 1/4 mile than your car.
I'm curious to know what I've stated that you feel is inaccurate or would indicate I don't know what I'm talking about.

first, what makes you think a sedan with a 3.7 would be heavier? the extra weight in the coupe comes from the redesign...engine doesn't weigh 300 extra pounds.
second, try being more clear in you logic and writing. you state that a difference in weight coupled with an increase in horsepower would show no increase in performance. why would anyone think you were comparing a 37 coupe and a 35 sedan, and then comparing that to a possible 37 sedan (with what you are sure will weigh 300 pounds more). when you talk about corresponding weight and power increase, as you stated in your reply, you should be comparing apples to apples. a 37 coupe and 35 coupe (which would be the logical comparison) there is a significant increase in performance.
edit: hence, since the coupe weighs an extra 300 pounds and shaves of half a second in 0-60 and 3 to 4 tenths in the quarter miles, it would be easy to assume that a 3.7 in and existing platform with thirty or so extra horses would have a dramatic increase in performance.

Reduce the Noise, Vibration and Harshness and make that motor buttery smooth (counterbalance???) so that the magazine reviews have nothing to complain about.
