Personally, I love high reving engines. I drive a Honda built car with an 8,000 RPM redline and boy is it fun. Sure, it only makes 270 HP and 224 lbs-ft of torque, but it is still very fast and fun to drive. I don't feel the slightest lack of torque down low in slow city driving as some might suggest. I used to drive a Mustang in High School so I understand Domestic Hot rod style low end torque as well, but I still have way more fun in my Honda I guess that is why I'm more of an F1 fan since I love those 18K RPM engines Bottom line for me is the end result. If the car performs and puts down the numbers the engine specs don't matter that much too me.

Just so that we're clear, there is a difference between allowing you to rev high and having to rev high to make peak hp.
G35: 306 hp at 6800 rpm. 7500 rpm redline.
IS350: 306 hp at 6400 rpm. 6600 rpm redline.
So while the G35 makes peak hp at a higher rpm than the IS350, the difference is not as large as the redline would have you believe.
In other words, you don't HAVE to rev up all the way to make peak hp in the G35. But the higher rev limiter is there if you want to have a little fun.

IS350: 277 lb-ft @ 4800 RPM
G35: 268 lb -ft @ 5200 RPM
We've already seen the IS350's torque curve, and 90% of the torque is already available at 2000 RPM.
5200 RPM for peak torque, on paper, looks like a Honda engine. I won't jump to conclusions, but I doubt that the VQ35HR will have a flat torque curve beginning from 2000 RPM.
Both peak torque and peak HP are reached at higher revs for the G35 compared to the IS350, so my point still stands that the engine is being stretched. That's also not mentioning the fact that the G35 has less torque, which no doubt was a sacrifice made in order to reach that increased HP.
Sure, if you want to have a little fun, that's what the G35's high redline is for, and it further cements the G35 as being mainly about sport, and less so about luxury.
I also wouldn't be surprised if the G35 has a freer-flowing exhaust for maximum performance, compared with the IS350's restrictive exhaust, which a lot of people say restricts power by about 20HP.
I can't wait to see the dynos of the VQ35HR. It will be interesting to see how much power it puts down on the ground, and if the 2GR-FSE is actually underrated.

Just want to touch on something here. I much prefer the feel of a soft luxurious ride, but I am realizing the benefits of a tight or sporty ride as some might call it. Its not just about carving canyons or the 'fun factor' of a stiff ride, its the 'safety' aspect. If u look @ the research you will find that cars that have a stiifer, tighter/ sport-oriented suspension are much better when it comes to accident avoidance.. the difference can be life and death. So the point is do I want a nice smooth ride or do I want something that has BETTER potential at saving my life.. I'll choose life and this will influence my future car buying purchases as it has not in the past.

Don't get me wrong, I like high rev engines too, but I was simply stating some engineering facts which can't be ignored. Although, I tend to find 4 cyl high rev Honda engines somewhat annoying, just because I personally dislike the growl they make. Subjectively, Toyota's 4 cyl high rev engines sound better, and I too love F1 engines. Not only that, but I also love V6 and engines, as well as high rev versions of those engines .
Simple fact is, the higher you rev, the less efficient the engine is overall, and therefore, the lower fuel economy you get. Also, generally speaking, a high rev engine with high peak HP tends to lead to lower torque and the low and midrange, and higher peak torquw.
You might bring up the point about Honda having such great CAFE numbers, but that's mainly because Honda doesn't build any production V8s. With this in mind, Toyota is right on Honda's heels in terms of CAFE numbers.
A fairly high rev engine that has high torque is just bliss, which is one reason why I really like the 2GR-FSE.

Anyway, one thing we are forgetting about is gearing. All the specs posted above are engine specs. By the numbers the 3.5 in the IS appears to spec better, but we really don't know what the torque manipulation is to the wheels after the gearing. It very well could be the G35 puts higher HP and torque at the same RPM points as the IS, or it could not. We just don't know until someone puts up the gear ratios, final gearing, and/or an actual side by side dyno run from each car on the same dyno/same day. Either way when it is all said and done the real world will see both these car perform very cose to each other. One bad launch from eather car probably means a win for the other since I believe they will be that close in acceleration performance.

THe funny thing is we are arguing and 95% of these cars won't even be pushed how we are talking, not just the G35 but IS and 3......
Most will be autos and in the G35s case, b/c its a great value.
And 8-10% going to fleet sales.
The new G35 is a logical and good improvement over the previous model.
Though not sure why Infiniti changed the car in what 4 years? Luxury car companies don't make full changes that quick.
I think for the price, like the TL, value will continue to be a huge attraction. You are getting 306hp for 325 and IS 250 money if power and a larger size car and a good price is high on your list. That is a very, very powerful arguement.

You guys are forgetting that the Japanese Skyline (G35) was out in Japan for a year before the G35 made it to the states as a 2003 model. So as far as the company is concerned, the car is on a regular 5 year cycle.

You're only telling half the story:
IS350: 277 lb-ft @ 4800 RPM
G35: 268 lb -ft @ 5200 RPM

But the fact that the 13 year old VQ engine (with revisions along the way of course) can hang with the brand new sophisticated GR engine speaks volumes to how great the design and guts of the VQ is.
And without the benefit of direct injection, which would have even added more power and torque.

I'm hoping they bring out a G25. There made a VQ25HR, no doubt to go into the 2007 Skyline 2.5. It wouldn't be that big a hassle to bring that car here.
A G25 will also weigh less and have better front/rear weight distribution, which would make it more nimble.

It's not bad, I just said I didn't like it. Totally a personal preference on this one, so no objective information to back it up with; I just liked when one model design stayed around for a little longer than 4 years - then again most modern car design is trash anyway, so I guess it's good they don't stick around.

You want constant change, that is what Hondas, Toyotas and Kias are for....

I doubt the current IS and GS will have 7 to 8 year cycles again. We'll see.
