Trust me, I do not do it often. Most of my time I am driving at 30-55mph. I have scene the highway/beltway/freeway probably 10 times since i had the car. I do, however, like to open the engine every once in a while since I barely get to drive over the speeds mentioned above.

 

Using the gear ratios, I estimated some max speeds (in mph) for the 5AT and 6MT:

==5AT==
1st: 41.6
2nd: 68.0
3rd: 104.5
4th: 159.9 theoretical (limited at 155)
5th: 190.3 theoretical (limited at 155)

==6MT==
1st: 42.1
2nd: 68.7
3rd: 98.4
4th: 125.7
5th: 159.8 theoretical (limited at 155)
6th: 201.3 theoretical (limited at 155)

 

Can anyone confirm that the 5AT can reach the speed of 155mph in 4th gear without needing 5th and if so, at what RPM?

 

not sure what gear but i know that it could hit it, and prob hit it without a problem..
some1 told me that he hit 143 in the 07 g35 sedan, so the g37 should be capable of doing it much easier

 

I have no doubt whatsoever that the G37 can attain a speed of 155mph.

 

I saw an image snapshot of an Auto G35 (previous gen coupe) pegged at 150+. So I think that the G37 can do it no problem.

 

How is that possible...our redline is 7500.

 

mis-typed.

 

Redline on both G engines is VERY generous, hitting 7800 is possible. My 05 coupe would hit 7500 before cut-off. It won't let it hang there, but for brief moments the ECU lets you play over the redline. The VQ is very strong indeed and they let you play, can't hurt this engine.

 

i dont have my car yet so excuse my dumb question. what do u mean by backwards pressure? cuz id def wanna shift down to 3rd from 5th...of course after the car is broken in!

 

hard to explain but while youre in D mode(regular) you can move the shifter down a little, so if you move it down and then switch over to DS(sport) you can reduce a step in downshifting while in DS mode.

 

How did you calculate these?

 

Quick Question Guys, Do the Paddle Shifters and the Gear Shifter on the Right, both do the same thing?

I ask because I see you people mention Three different options:

D,DS,MM

 

Yes the paddles do the same as the floor stick. The paddles can be activated in any mode. In D mode using the paddles willtemoparily allow you to manualy shift then after a few seconds it will go back to regular D operations.

 

O Maybe thats the Reason I havent learned how to use the Paddles yet lol, I guess you have to have the Floor Stick in Manual Shift too before using Paddles Right?
