Don't expect the motor to be underrated, or you'll be in for some disappointment. If you want to go by the magazine figures, I estimate the new Z 0-60 times will be about 4.8s and 1/4mi in about 13.6s.

The new 6MT G sedan is just as fast as the IS350 (AUTO). The IS has a bit more peak torque. I would like to see what the IS350 dyno graph would look like on top of the VQ graph just to analyze the characteristics of the motors.

 

i agree on your times but really the 13.6 time id have to say any lousy driver will get it, you will see faster than 13.5's stock by many

 

Nice, the more i hear about this car and new motor the better. I really don't know what iam gona do. I have to be patient i have the money to buy the car but i will waite for the 07.

 

I also agree that the hood is the only thing I don't like.
Other than that, the new motor should be sweet.

 

The LA autoshow which just finished is coming up to San Francisco late Nov. You think they'll allow ppl to go inside the '07 Z then?

I just don't understand what's the big deal w/ letting ppl see it if it's just minor changes as indicated. Even the '08 G35 coupes have had their interior shots shown -_-;

 

Its because the entire inside is CF with custom made racing seats, a smoothie machine, jenna jameson, a mini starbucks, and much much more.......

 

Hey, if you or anybody else is planning to go to that show in S.F. I have a small request. If they let you open it up... engine compartment pics please. If they don't let you open it, a pic from behind and underneath with a flash to see the exhaust setup. Thanks in advance!

 

310-315 hp
0-60 5.0-5.2 sec
1/4 mile in 13.4 @105

just a guess

 

In one test it even trapped 103 in the 1/4.

 

The Z GT-S has me scratching my head at the moment. O_o

 

I'll stick with my 03' thank you very much...

I've never liked the new headlights, and now that hood

I think the review saying that its getting softer is a good description. I like my impractical, hard riding, heavy clutch, cheap interior, no storage, and my damn tranny rattling away in neutral...

 

Lol the VQ over 6,000 rpm makes me that's why I want the HR

 

I asked this in another thread, but didn't get any input.

Someone enlighten me as to why a newly introduced engine like the 3.5 VQHR will only live ONE year on the '07 Zs and then jump to a 3.7? We already know the '07 Z and G35 sedan will get the HR.

I have my share of doubts that the 3.7 liter engine will make it so soon, because if Nissan needed a boost of power in general, they could of easily altered the current VQ to 3.7 to gain it w/o spending so much on r&d for the new HR.

I highly think the 3.7 will arrive at least 2-3 years AFTER the release of '07s G35 Coupe to be used in redesigns in both the Gs and Z. Because Nissan was able to develop the HR to extend the Z and both Gs' to a possible 350hp (100/liter), there is no point in using a superior 3.7 engine now and keeping it for future G/Z generations. It's pretty easy to see, the revised HR engine is to the revised Gs/Zs while the current VQ is to current Gs/Zs. Both the revisions in design and engine go hand-in-hand as an intermediate step to the 3.7 liter.

If you look at the timeline, it's pretty convincing as well.
Current VQ engine was slapped into the G/Z in '03.
Fast forward 3 yrs to '06, new VQHR confirmed to be in G/Z

As I've stated above, I believe the new HR is here to stay for that same period of time, 3 yrs until we see 3.7 introduced.

The same can be said about the horsepower of the future G/Zs up to 350.
Introduction of G/Z ranged from 260-287.
Fast forward 3 yrs and we have 298-300 for both those cars, that's range of an additional 40 hp.
With the new HR and assuming Nissan will slowly upgrade the hp like they did from '03-'06, the new G/Zs can easily expect 350 in three years.

So that's my analysis, feel free to correct me. I pulled those hp and dates from Wiki.

 

I agree with your bug eye statement. On another note, in terms of functionality, they are superior to my 03 base lights. They don't iluminate at night properly even with my sylvannia bulbs. I would swap just for my safety. Function beats pretiness.

 

3.7L engine are just rumors. nothing confirmed.

 

Not going to happen on those numbers, the current Z produces 300 hp and still only does a 13.8 in the 1/4. Its going to need at least 330-340 hp to pull a time like that.

 

... but look at the new G numbers... increase of only 8 hp, and times decrease by about .5 seconds

 

13.4@105??? you gotta be kidding... i highly doubt it. maybe 13.6 or 13.7. but not that low. it's unlikely that nissan would be improving performance by that much on a Z that's on the verge of a major make-over in 08 or 09... (unless they're planning on FI or significantly bigger engine)

also, 8hp increase on the new G is under the new SAE rating. under that rating, the 06 Z would be measured at low ~290s hp... 03-05 Zs at less than 280 hp. so from that perspective, the new VQ is a very good improvement from its previous models, considering that the displacement has remained the same.

also fyi, trying to improve 0.1 sec on 1/4 mile times in the 13 sec range requires a lot more power compared to power needed to improve 0.1 sec on 1/4 mile times in the 14 sec or 15 sec range.

 

^ I read somewhere under the new SAE:
298HP => 293HP
287HP => 275HP*
280HP => 270HP*

*Something like that ehehe.

 

do you think the HR motor will drop into a 03-06?
