07 and 08 Faster then the 09 g37 sedan.

[zozoka1212]

Car and Driver tested the 09 and came out slower then the 07 and 08.

I guess I made the right decision.

Looks like the improvement is in MPG.....

Doesn't the 07-09 Sedans REQUIRE prem. gas just like the Coupes???

The difference in price (prem. vs. reg.) not such a big deal, BUT the fact that it becomes so scarce at times like these bothers me.

I really think Infiniti should have two lines---G-35 coupe and sedan----for those who want the thrill, harshness and excitement, and G-37 coupe and Sedan---for those who want luxury, refinement, and looks. Just my 2 cents.

I still feel the G-35 coupe and G-37 are two entirely different cars. They are not upgrades, at least in my mind.

[Tampa G35 Sedan 6MT]

I still think the upgrades are great!

I don't think that the test conditions are the same either!

I also have a question. If the HP is 328 at 7000 rpms then what is it at 7600 rpms?

I don't like the wheels and I still think i might go for the 6MT. I don't really need an X so why add the weight and why give up the 6MT.

I also think you can get a better price on a fully loaded 6MT just because they would play hell trying to sell it!

Jacko, well said!

Very possible the test conditions are not the same and maybe some SAE correction is needed to truely see which car is faster

To answer your HP question, 7000 is where the car makes PEAK hp, its still making power all the way up to 7600 rpm just probably a few ponies less

All they have to do what some of the german competitors are doing. Have a switch between sport and normal driving. Have a few diferent maps for the ecu. Each G should have 2 different personalities.

So if I was trying to get the best track time is it better to wait to 7500 rpms on my G or shift right at 7000?

If You are making 300 at 7000 and 295 at 7500 then It would be better to hold the gear right. Because if you shift at 7k then you will be at X Rpm after the shift in the next gear and that would probably be making y hp vs y+ a higher rpms hp in the next gear to start.

Clear as mud right

ok so say from each shift you loose 2k rpms

so if you shift at 7k you then go to 5k in next gear where if you wait to 7500 you then go to 5500 in next gear.

Isn't it better to stay higher in the power band?

IMO the hirhger RPM you can shift at the more RPM you can carry through the gear the faster you accelerate

[Tampa G35 Sedan 6MT]

That is what I thought... I always wait until 7200-7500 to shift when WOT is needed or wanted

[Sentientbydesign]

The goal is to stay within the power band. Shouldn't be hard with a 6 speed close ratio transmission.

[Jacko3]

Nate:

Would a short shifter make shifting to stay within the power band, any easier. at the risk of wearing out the syncros prematurely?

[Jacko3]

Thanks!

[Jacko3]

I agree 100%.

For best acceleration, you need the most torque at the rear wheels. To compare torque in different gears, multiply the torque curve (assuming you can find it) by the gear ratio. What you would most likely find is that, although the engine puts out less torque at maximum rpm, multiplication by the lower gear ratio more than makes up for it. Therefore, stay in the lower gear as long as possible.

I find the shifting distance on the G to be pretty short as it is. My wife's celica has an even shorter throw that I'm not fond of.

The short shifter could theoretically shave off a few 10th, I suppose. The question is:

How long does it take you to move the shifter 4"?

[Jacko3]

Nate:

Nice question, worthy of being researched.

[Jacko3]

Kendahl:

I agree 100%. I actually get to 60 miles per hour in my 2nd gear alone, before it runs out of air, and requires me shifting to third, which runs out of air at 90 mph.

I guess, the tested '09 car didn't run even 600 miles and performance should be better after 2000 miles (and oil change).

Anyway I would like to see 2008 G35xS vs 2009 G37xS test comparision and I guees G37 would win!
