I love the sound of the motor when i rev it up. It loves to be revved i mean after all its called HR (high-revving) engine.
But i do find it ironic how we have a 3.7L V6 compared to the new BMW e92 4.0L V8. Nissan pushed every little bit of power they could out of this motor while BMW throws a small high revving v8 into the M.
I would be happy if we got small displacement high-vevving v8....or a turbocharged I6.

Since Infiniti is expanding the G line-up with the G25 that mimics BMW's 328 and 335 and Lexus' IS250 and IS350, perhaps they will come out with a real competitor to the BMW M3 and Lexus IS-F.

I must be really easy to please. The car goes fast, the engine doesn't have problems, and all I have to do is feed it fresh oil every 3 months or so and I can keep driving the hell out of the car with no issues.
It's not as smooth as the engine in my IS350, but it's also a lot more fun. The G has a coarser engine than the competition, but for me that makes for a more visceral experience. That coarseness only comes on when I'm really getting into it at 5k+ RPMs, and a little bit of thrashing seems perfectly reasonable at high revs.
No complaints here. As a matter of fact, the "issues" that people bring up about this engine are really the things that put a smile on my face and brought me to Infiniti in the first place.

The VQ sound harsh because it has a timing chain. The Acura has a timing belt, and it is smoother and quieter until you have to pay for timing belt replacement. Heat issue on the G is related to Infinity cut cost and did not put in a oil cooler, even a water oil cooler would have helped and does not cost as much.
I don't think any motor can compete with the BMW for smoothness.

Alright, I'm a complete novice with all this engine talk. Coming from a honda (2005 Acura TL), I know a bit about VTEC and UA6-UA9 motors, but I don't really see how VVEL compares. Can someone break down the logistics? Our G37S' have...the VQ37VHR motors, or HR motors? Is the VVEL system in our cars, the same as in the Toyota and Lexus cars (we have both and I believe they both say VVEL). Lastly, how the hell does VVEL even work?! 
thanks guys!
thanks guys!

+1 for V8! I want Infiniti to put the 390-hp 5.0 V8 from the FX50 into the G ... imagine a G50!!! (Although the 420-hp 5.6 V8 would be nice too! ... a G56) Mmmmm. This would make for an interesting comparison against the Lexus IS-F. Although I would settle for the lower powered yet much torquier 325-hp 4.5 V8 from the previous generation M - that is one amazing sounding motor!

hmmm....it would be interesting for nissan to bring back their I-6 turbo charged engines...it would be faithfull to the skyline lineage. of course that would be for the next gen.

That's what a lot of people seem to be missing. Sure Infiniti can build it but do you know what they'd have to charge for a G56? Look at all the people who were complaining about the M's price tag when it came out.

Infiniti did cheap out on cooling, but they are also correct in assuming that most users won't need an oil cooler.
That SOHC J35 from Honda makes 16 less HP than the VQ35HR on 87 gas and with less revs. It also costs about 1/2 as much, if you ever need to replace one. Lets not forget it gets better MPG (by far) and has higher volumetric efficiency.
Infiniti's been focused on ouput, while Honda's been focused on efficiency.
Both engines, as well as the N54/55 and 2GR-FSE have all fallen off of Ward's 10 best.

thanks guys!VVEL is a Nissan/Infiniti trademark so you won't see it used by Toyota. You're probably thinking of one of Toyota's timing systems: VVTL-i, VVT-i, VVT-iE, or the new Valvematic.
VVEL can be compared to Toyota's Valvematic or BMW's Valvetronic.

LOL ... I would equate the G37 IPL coupe to the BMW 335is coupe - some more power, subtle body changes, tire/wheel upgrade, etc. But clearly the G37 IPL can't compete with an M3 or IS-F.
Re: $60K for G50 ... Maybe not THAT much, but sure it would push the tag to over $50K. A lightly optioned M3 without the dual-clutch tranny pushes $63K and the IS-F, with the one option package available, is nearly $64K. I think a fully loaded G50/G56 for $55K would still be a great deal - and would give Infiniti a fully fleshed-out line-up and a G capable of 0-60 times in the mid 4's and 1/4 mile times in the high 12's. Maybe Infiniti would even consider dropping in the GT-R's 6-speed dual-clutch ... clearly I'm dreaming.

I have both the G37 and an IS350 and can say without a doubt that the 2GR-FSE in the Lexus is a million times smoother than the VQHR37 in the G. Going with the auto tranny this time around seems to have blunted some of the NVH but its still prevelent. Still, I don't really mind it too much. Our Lexus is smooth, but it also feels a bit sewing-machine if you know what I mean. The VQ never lets you forget that it is working its butt off to make max power. Plus there is no contest in sound quality between the two. The IS350 barely makes any noise at all but the exhaust sound of a stock VQ always gets my attention....
