7AT Nissan 370Z Accelaration Video from Japan 02.04.09
 

Okay, this is probably NOT the best quality video but it gives you an idea how fast the new 7AT is. Judging by the video it seems pretty fast. Here are more info on 7AT gearing.

I am going to go ahead and say they were pretty impressed by the power ;).

7AT for the win, taking nissan to a new level of refinement and success

Man ! Im so torn now between manual and auto was there a thread that clearly shows the pros and cons of the two? :confused:

Yeah, the Auto is going to accelerate faster (most likely) but the manual will be more fun! As soon as I break the motor in, I'm going to power shift the sh!t out of it and see if I can chirp 4th!

Agreed. The AT will be faster but the MT more fun. I am still leaning towareds the AT...

I am stupid when it comes to the gear ratios but I know higher the number, better SOTP accerleration but you lose top end since it's reving higher sooner. My question is do you look at the final ratio or the 1st gear for how the car will feel upon launch?

I will be really surprised if the Auto is faster than manual. I think the manual is faster because,

1) 370z auto transmission is not same as BMW M class, or any other supercars. I have heard that there is little bit of lag between gear shifts.

2) Auto loses more whp than manual. it is usually 15% loss for Manual, and 20 - 25% loss for Auto.

3) Auto 370z weighs more than manual one.


By the way, the Syncro Rev also helps in upshifts for the manual in which it holds the rpm for couple of mini-seconds, just enough for the smooth gear shifts and continous flow of power between gears. I think this is very advantageous feature because, there seems to be No loss of power through upshits with no Jerking. Syncro Rev is simply amazing...


Until I see the factual test numbers of 0-60, quarter miles...I think the manual is still faster than Auto.

What do you guys think?

It all comes down to the granny-shifting driver.

I tend to agree with you even though I wish 7AT was faster than manual :)

I drove the 7AT before my 6MT came in, all I can say is that I was under-whelmed and uninspired. I am sure I would get used to it, and it would be great for sitting in traffic, but if I weren't getting the 6MT Z I would be shopping for a different car.

Even the BMWs new DSG tranny is not as fast as the 6MT version (E90-92) M3s. Same thing applies to the GOLF GTI with DSG vs Manual. All those cars have better 0-60 times with DSG tranny yet they still lack the trap speed that the 6MT version puts out.

I have personally seen 6MT GTI vs DSG GTI on the freeway and 6MT starting pulling after 70mph. There is also official video from europe testing out the 6MT M3 vs DSG and 6MT walked on the DSG from 40-140 mph on the airfield.

When it comes to the 370z 7AT will be quicker and more consistent on the street and sometimes on a 1/4 mile track. Properly driven 6MT will be quicker than the 7AT especially after 2nd gear.

^^ Look at the G37 guys... 7AT is faster than the MT....

Cause G37 guys cant properly drive manuals....

For 6MT drivers it takes time for you to get consistant with 6MT when it comes to launching and shifting fast. I have been driving MT since 12 years of age and it took me over a year to get consistant 2.1 60ft times with my 6MT G sedan. I had the car for almost 4 years and i was still learning something very minor when i went to the drag strip till the end. Every car is different and there aren't too many people that can drive it as fast as it is capable of.

As i said earlier 7AT will be more consistent but properly driven 6MT will be quicker.

Not really. They are just (obviously) more consistent. The gearing in the 7AT has an advantage in its first two gears but after that, there's no real advantage to the 7AT. Another neat feature is the fact that the torque converter is always locked on the 7AT.

...ofcourse, the 7AT really closed the gap that the 6MT had on the 5AT. But I would still bet that a properly driven 6MT can take the 7AT around any road course.
