Hey ... check this test drive analysis over at another board:

http://forums.vwvortex.com/zerothread?id=2677357

It compares the new G against: Audi A4 2.0T, Lexus IS250, Acura TL, BMW 325i, and a 1st gen G35 sedan. A good sign of things to come, based upon one person's perspective.

 

Can't waite untill i get a test drive...Question why the hell there testing the new G with Is250 and not the 350.....

 

Price comparison ... Infiniti would want to capture those who would cross-shop for a similarly priced car.

 

Excellent find. I supose the price comparison makes sense at this level, but I am anxious to read the mag. reviews which will probably be out....Sept.? I'm sure Infiniti has dates booked with Car and Driver and MT and R&T alreaday. From what the guy said, seems like we have a lot to look foward too. Wish I got picked for that reasearch stint though....$150 to test drive a car.....

 

306hp @ 7500rpm and 268lbft @ 5200rpm.....
pretty good, but probably not enough to reliably edge out the 335i and is350
then again both of the above cars will be significantly more expensive..

 

For an '06 IS350 $40,590.00* '06 G35 39,100.00** Very similarly equipped (as close as can be) I wouldn't say that was a significant difference, but.... an IS extremely equipped is more like $44,784.00*, if I were going to spend $45k, I think I'd move up to an M35, or GS.

You hit the nail on the head with your last point. All things being EQUAL, the G35 will end up being between $7-8K less than an IS. Once the initial rush burns off, you'll be able to get a nicely loaded G35 with everything minus a NAV for around $35K. You'll also be able to take advantage of 1.9 or 2.9% financing incentives that Infiniti offers. If you're paying cash for the vehicles, the G35 will be $7-8K less than the IS. If you're financing, the difference over 5 years could be as much as $8-10K. Once again, I'll take the G35 over any other vehicle priced at $35K. Compare the M series to the IS if you really want to be fair.

 

Where are those figures from? The HP and rpm don't seem right. Most high performance NA engines are making 100HP/L @ 7800rpm. e.g. Civic Si, RSX-S, BMW's M models, etc.

The VQ should only need to rev to 6800rpm to make 306HP. Another way to look at it, it should be making 335HP @ 7500rpm.

 

You can't make a generalization like that. Every engine is different. Besides, the revised engine will make more HP, and torque,(compared to current 6MT) AND get better fuel economy too, who's complaining? Not me!

 

Jspeed is right ... based on the RPM's and displacement ... this G should have AT LEAST 325 HP

 

all we can do is wait and see on the hp/tq numbers. this wait is killing me.

 

The VQ does not use such high tech gear as Honda's iVTEC, or BMW's VANOS systems, so the specific output per liter will be lower. Nissan chose to forgo those expensive and complex systems and instead simply increase displacement to gain the power they wanted. The result is a less peaky engine with a better torque curve. Do a little research before you make blanket declarations like that man.

I personally really like Nissan's path with their engines. Build just a few very high quality engines, and use them in nearly all of your vehicles in tune levels to suit. This is essentially the same engine that wil be used in the Altima, Maxima, Quest minivan, Mirano SUV, FX, Pickups, Exterra, etc. They save some money this way by not developing 5 different engines and that helps the customer in the end as they can keep costs down while still delivering a great product.

 

Actually, they have gone the route of the CVT which can't hold as much power as the standard autos. The new Altima and Maxima will have the older VQ series rated at 255hp. The FX and Infiniti line should have the more powerful engine.

 

feeshta ... hey "MAN" ..stick to discussing "car audio enthusiast" topics.

I was just stating my opinion

"Do some reasearch" yourself man ... First off, what you knew about VQ's is all about to change in this, the fourth generation which "has been significantly rethought, with approximately 80% of major parts (except bolts, O-rings and clips) redesigned" says infiniti.

Based on the current VQ Specs, in conjunction with the following facts:

1.) 80 percent new VQ w/ a higher rev limit (increased from 6,600 rpm to 7,500 rpm) and higher compression ratio (10.6:1 versus the previous 10.3:1)
2.) two-stage intake (reduce airflow resistance by 18%) and a new dual-exhaust system (reduced muffler exhaust pressure by 25%)
3.) said Igo. “And secondly, the tuning strategy that is not strictly about standing-start acceleration, but a more refined balance of quick acceleration that builds continuously to the redline. It’s a deepening pleasure that keeps getting better as you drive."

... with the above info and using simple HP rating formulas ............ 325 Peak HP is on the conservative side ... would not be surprised if its more.

 

I recognize that there are quite a few improvements going into the new VQ, but the guy who did the 07 comparo for the research company said the specs were 306 hp at 7500 rpm and 268 ft lb of tq., with a 2mpg increase in both cycles. I don't know how reliable that information is, but it sounded pretty legit. Also, the g35 does not have direct injection...which allows higher compression and more power as well as better economy. The IS350 is equipped with direct injection, as is the new 335i, and many others. Considering that the hp would be measured according to the new SAE standars...I'd say the new engine is gaining anywhere between 35-45 real hp...as compared to the current auto, anyway. Of course, Nissan leaves plenty of room to juice their engines up, especially when a competitor comes out with something just as powerful. G35: 260, 280(in response to TL's 270), 298. Altima: 240, 245(in response to Accord's 240). Nissan likes to edge out competitors for the 'best in class' rating for hp/acceleration, and leaves some on tap for future competitors, so I can clearly see 325+ hp in another year or two, but for now, 310-320 sounds more reasonable. Just my opinion.
