You're too selective; the Porsche GT3 isn't going to give you a power seat either. I also imagine that 99.999% of Infiniti's customers want power seats. All that weight Infiniti added to make the car plush, quiet, and comfortable is counter to making the car lighter. You can't have your cake and eat too.
I totally understand your points, I'm just giving you a hard time. I think Infiniti has done a pretty good job with their option packages. It's not like Acura where everything is included, but it's not like BMW where you need to load up on 7 different options, basically forcing a built-to-order car. Premium + Nav is all I needed on the Infiniti, whereas the BMW needed - Premium, sport, nav, comfortaccess, heated seats, metallic paint, and I'm sure there are more I'm missing. Finding that combination proved impossible and I didn't want to order a car.
I'm glad you realize the difference between the STI and the G35, and at the end of the day, I doubt they're crossed shopped much at all, but most enthusiasts on these sorts of sites get caught up in performance.

Additionally, Car and Driver and Motor Trend have weighed the G37 coupe and G35 sedan, and the coupe is a legit 3,800lb car with fuel. The sedan is a legit 3,600lb ride. Infiniti flat out admited the reason the coupe is heavier is because of the additional reinforces required for the large doors and openings.

08 G37 coupe = 3,717 lbs:

08 G35 sedan = 3,583 lbs:
http://www.caranddriver.com/features...initi-g35.html
3717 - 3583 = 134 lbs
But, we're really splitting hairs at this point. If you actually read my post, you would see that I pointed out the fact that the 2005 G35 sedan gained about 150 lbs (143 to be exact) over the 2004 G34 sedan when it went to the 298 hp rev up motor. Both of those cars had the exact same 3.5L of displacement. So, obviously I am not arguing that added displacement alone would necessarily increase weight on a car.
That said, I do think the G37 motor weighs more than the VQHR35 because the 3.7L motor comes w/ VVEL which the VQ35HR does not have. That alone will add a few lbs (obviously not 100 lbs or even 30 lbs) but maybe 10 - 20 lbs? It certainly wouldn't be lighter.
As I'm stating for the 3rd time, weight will come in other areas such as a slightly beefed up transmission to handle the added power and perhaps the larger 14" brakes from the G37 and a few other new options and tweaks here and there that inevitably add weight to a car as it progresses in its model cycle (see prior comparo btw 2004 vs. 2005 G35 for evidence of the weight increase).
Finally, the "260hp" 03/04 motors were putting out closer to 275hp and the 280hp motors were actually making closer ot 275hp. Hence the reason why that motor was rated at 275hp in the 07 G35 coupe and why there was no performance difference between the 260hp and 280hp motors.

Let's just call the G version an extreme Sport edition, for those that are willing to sacrifice some of the "luxury" for some more "Sport". Granted, it would probably not work well with the sedan so maybe it should be a coupe exclusive.
I for one do not feel the need for items such as Nav, distance sensing cruise control, and other technological wizardry that is a distraction to the driving experience. I don't feel the need to push buttons and check screens and see which song I should play next. Throw on a cd (or cds) or tune in your favorite station and just drive, seeing where the road will take you. Enjoy the curves and scenery.
Worst idea; maybe, maybe not.

This has been one of my largest complaints about Nissans. Although it doesn't seem to really affect resale value (still strong), it's annoying. BMW will keep their 335i relatively the same for 4-6 years

In the EU they sell an e46 M3 CSL which uses a lot of carbon fiber pieces and has extra weight savings. They never imported them here although some of the parts like CSL front lips, trunks, etc. are imported and put on USDM e46s here. I think BMW realizes that in the US they're a luxury brand and their sales would be only limited.
Porsche on the other hand sees themselves as a sports car maker and offers the GT3 in the US, but again, almost all GT3s sold are used in track events. My neighbor has a 997 Carrera S and it's clearly a sports car but it still has power seats, nav, AC, a stereo, etc. I wouldn't have it any other way. A car is a form of transportation or it's a race car. There are compromises I'm not willing to make for a little more performance. Also, I bought the Infiniti because of its value and it's decent performance and luxury offering for the price. People on this forum tend to lean more towards the performance side, and for some of those people I think they purchased the wrong car.

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.

Unless they plan to make changes along the same scale, I don't see much of a weight increase at all.

[QUOTE=DaveB]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

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