Is there a REAL performance advantage of the 2nd Gen over a 1st Gen sedans?

Assuming the old engine was based on new guidelines it'd be significantly lower, or vice versa. I havn't seen anyone with the HP difference based on same guidelines though, I'd be interested to know too!

I would love to see a stock first gen (apparently the video I found was not a stock first gen) -vs- a stock second gen on a track..and be great if it was sometype of road course.
Something is amiss in my mind because perhaps Nissan is sandbagging it's claim of the HR motor or was over claiming the figures of the non-HR motor.

"Faster" in a quater mile does not tell you if the winner has a faster car. It means he's a better driver, better tires, track condition = better launch. "True" power is measured at the dyno and even then the numbers still fluctuate depending on conditions and it does not take the weight of the vehicle and driver in to consideration. This is assuming we are talking straight line race.
Of course if the disparity between engines is greater such as 400HP vs 300HP can make up for alot on a straight track.

The 2nd Gen G is clearly faster than the 1st gen. I really dont need 1/4 mile videos or any of that bullsh*t to verify. Drive each one back to back and the 2nd Gen G is simply a rocket compared to the 1st gen. Ive driven each, plus my coupe, and the VQ35HR in the 2nd gen G simply hauls way more a.ss than my coupe or the 1st gen sedan. My 6MT coupe feels slow in comparison and my car never really gave me the "pushed in the seat" feeling, and trust me, I know how to drive. The 07 Sedan DOES give that feeling. Turn VDC off and mash it from a dig and the 07 Sedan pulls like a beast. The VQ37VHR in the 2009 Sedan is gonna add even more response and more power throughput. Im predicting to see 13.5-13.3's in the quarter with a stickier set of tires to achieve a good 60ft. from a competent driver. My next car without a doubt is going to be the 2009 Sedan. With a JWT lightweight flywheel, HFC's, the best exhaust at that point in time, and 3.9 FD, I greatly believe this car will be a high 12-second car.

Truth is we don't have yet a definitive word of what motor (and power output) the US 09 G sedan will have. It'd be great if the VQ37VHR won't be detuned in the sedan, but that would mean the sedan would be even faster than the coupe. Marketing can't have that, now can we?
Customer : "Why does this 2009 G37 Sedan have the same motor as this 2009 G37 Coupe, yet the Sedan still makes 306HP? What was the purpose of this higher displacement motor? "
Salesman : "Uhh, uhhhh, since the sedan has 4-doors, that means its heavier than the 2-door, uhh, uhhhm, oh! and it keeps the engine from maximum output, yeah, thats the reason why!"
Uhhh no.
The new Z will be getting the VQ37VHR, hence 370Z. It WONT be getting detuned, and it will most likely be "making" more power than the G37, lets say 340, but we all know its purely for marketing reasons, cause I bet the Z's VQ37 will be EXACT to the one in the G.
Infiniti is all about competition. Why would they "detune" a vehicle when they can clearly "keep the tune" and have better performance from their engines, better than their competition? The VVEL obviously enhances performance and fuel economy, I highly doubt Nissan would R&D it for no reason. I will put ALL OF MY MONEY on it that 2009 G37 Sedan WILL have 330HP or more.

just like how we read that the fx was supposed to get the 3.7 for 2009 but didn't? still using 3.5?
i hope it does come in 3.7 and not detuned, but as of now, it's all speculation
imagine worst case scenario, 09 still gets 3.5, no new 7 sp a/t, everything same as 08 and interest rates go up (hard to beat the 2.9 or whatevers out there recently), so that's time wasted waiting around, time should be spent driving the car you want
and i disagree, 2 door = need to be faster, idea behind it is to be more sporty, more performance oriented

Tuning for MPG will obviously output less power, but the MPG gain can be significant.
The Honda K20 could be a good example.
The MPG versions are 160hp, and the performance versions are 200. Both use VTEC, but there's a pretty significant MPG gain for losing a bit of power.
It would appear the VQ37's hp loss isn't as significant as apparent in the European G sedan.

From what I've been reading, the 1st generation car is about the same horsepower like 298 hp. Am I getting the information wrong?

I raced a 2004 Coupe 6MT with my 2nd Gen G Sedan and all I have to say is that when I enter 3 gear the race was over. Above 100mph the G coupe was about 3 car lenghts behind. Mine is automatic base form. Still the G coupe looked nice and is in no way inferior. Is just "outdated" compared to our total HP and power graph curve. He dynoed 240whp, just for reference.
