The Int. did come a long way from the 1st G35. Why didn't Infiniti put the 3.7 in the sedan and the M35 I don't understand automakers these days

 

Didn't Lexus do that to the 1st LS changed the car A lot but it still looked the same.

 

30whp with a better powerband and gearing can definitely give you 7 tenths on the 1320'

regardless i agree with all your numbers but think the trap speed will be a few mph more.

to put it another way, at 280whp with good torque i expect it to relatively match the e46 m3 in terms of acceleration...

 

Comparing it to a M3 really isn't fair. It's not the same car.

There are several factors make the M3 different than the G35 sedan as far as 1/4 mile times. Some of these are:

HP/Weight ratio
Traction (weight distribution =/ traction)
Gearing
Tires
Drag

I have been to the track a lot in my day and .7 is a big deal. Is the gearing in the G37 really better? Is that an established fact? Will the powerband really be more 1/4 mile friendly?

 

335 - 340HP from a 3.7L VQ V6? First off, it would have to rev high, likely above 7000 RPM in order to achieve that. Either that, or use some new technologies on the engine. Also, that number would be embarassing for Nissan's 4.5L VK V8 engine, which has around the same output. That is of course, unless Nissan is planning an all-new V8 soon, which I highly doubt.

 

Im not going to speculate on HP, 1/4 mile times, 0-60, etc., but I will say this, I wouldnt be suprised to see this engine rev to 7k. The current VQHR revs to 6,800, so I would thinkg 7,000 is feasible. As for a new V8, I will not speculate here either, but it seems about the right time for a new one - remember, many people also doubted the new coupe would get a 3.7L.

 

have they release officla pictures yet?

 

Nope, no official pics will be released until the NYIAS.

 

first off, i was referring to the g37... apologies for any confusion.
having said that, both the g37 and m3 will likely have similar weight...and although the whp is likely to be similar, the g will torquier (sp?) due to engine design differences. regardless, hp wins races and i expect the g37 to easily match the s54d m3.

regarding tires, id say the G comes with competent tires.. and the car is far from a brick- i wouldnt be surprised if it werent more aerodynamic than the e46. on launching , the FM platform isnt a bad platform and on its own with 280whp in a Z/G can rival an M3 in terms of acceleration... and the FM platform has allegedly been significantly stiffened in the G37.

the move is only a surprise since the introduction of the vq35hr... no one really thought theyd still do a 3.7L car so quick after just releasing the 3.5L HR. that the engine was coming wasnt a huge surprise though- nissan had trademarked the names g37/m37/fx37 some time ago.

FYI the VQ35HR revs clean to 7,500rpm and delivers roughly 265whp in stock trim, with single exhaust. the final drive is a very lazy 3.5:1. there's no reason why a 3.7L version of the engine with dual exhaust (99% likely based on the fact that even the 2.5L altima has dual exhaust..and the new G sedan has equal length headers+dual exhaust) can't do 280whp+. And if they decide to step up the gearing (to be as aggressive as the vq35de nonrevup was, on a relative basis), cars like the E46 M3 won't be able to match it on the open...

 

My 2 cents, as the speculative posts and mag racing is cute
I not only drag my GS, I help HOST drag events twice a year

So here are real world results at the best 1/4 mile track in GA.
1st gen G35s do high 13s to mid 14s in the 1/4
We just had a 2nd gen come out to the last one, doing high 13s to low 14s in the 1/4.
M46 M3s, mid to low 14s in the 1/4 mile
IS 350s, low to high 13s in the 1/4. We just had a STOCK IS 350 do the 1/4 mile in 13.4 seconds at 103 mph! We were shocked.

With the track, your first run is more than likely going to be your best, its early (cooler), hopefully you prepped the tires (warmed them up) and your engine is coolest. An automatic is going to be easier to launch as well, especially to those of us who are not semi-professional drivers.

The mag racing and speculative results seem to be best conditions, best car used.

As for my, my GS 430 feels slow in comparison my best run in my new GS 430 is 14.5 at 98 mph in the 1/4 mile...Amazingly the IS 350 is a full second FASTER!! I've raced them side by side and seen my newer, smaller brother car whoop my behind!!!!

Last fall, I hooked up the East Coast AMGers to come. Mercedes even brought a E63 and CLS 63 out there.

The E55s, as stated on the internet, were faster in the 1/4 than the E63. E55 in low 12s, E63 in mid 12s.

 

Just when we thought INFINITI was going to add refinement, instead they choose more vibration by enlarging the already not too refine VQ. However, I just test drove the new Altima 2.5s AND IT IS VERY REFINE and Drives more like a coupe. There is still slight vibration from engine upon throttle dipin, but smooths out and pulls cleanly and makes nice noise towards redline. Camrys 2.4L was much noisier in comparison.

 

I won't speculate on the new engine's refinement yet but I will say Nissan has a big challenge. The SKYLINE in Japan is a huge name, and people have high expectations for it. Thus, it has to remain a little "rough" b/c that is what they want in Japan. However in America, it is a luxury badged car, so it has to provide what luxury car owners want. Its a tough blend with one car but I think they can pull it off again.

Case in point, the Brembo's. The JDM guys loved them in Japan, true race bred brakes. Of course the enthusiasts loved them here in America but enthusiasts makes up the minority of G35 sales (and most luxury car sales). People in America that were not enthusiasts were complaining they wore to quick and were too aggressive. Thus Nissan dropped them here, b/c the majority had spoken.

I am sure this engine will eventually make its way into other Nissan products.

 

Ya, I just don't think it'll have a better powerband. The powerband on the G has been getting worse as they revise the engine. The added displacement (and if they add DI) will help, but as mentioned it will not be surprising to me if this car revs well past 7k, and required 5k of those to hit peak torque. But ya, I guess we'll see. Maybe it'll run 12's.

Oh, and the guys talking about track time; you guys aren't the only ones that track your cars. When we talk about magazine times we do it because 90% of people are going to look at those rather than tracking the cars themselves.

 

Regardless of whether it runs low 13s or not, it is impressive Nissan is adding that much more hp in its 2nd generation car. It seems that they are definitely going the more performance oriented route. Too bad they chose more displacement rather than a turbo motor. Oh well, I guess we will have to wait for the GTR. It would've been nice to see a Turbo version of the G to compete with the 335i however (in the same price range as the current G).

 

Wonder if Lexus will counter that with an IS370 or IS400? Or just have Yamaha redo the head on the 3.5 for more topend HP.
