The AT adds only 36 lbs.

Shift Lag is 500 milliseconds

Power diff - unknown at this time.

Gearing - could be the difference.

A good MT driver can probably get about 300 milliseconds so assume a .2 sec loss there 0-60 (only 1 shift). Some AT's act as a slight torque multiplier (I have no idea why). This isn't a true dual clutch but it does seem to be one of the bests traditional AT's I've seen on paper. It will be down to how much gearing will effect it and driver error for the most part. Top end should go to the manual due to slightly greater power loss though the AT. The big news is that if it's the same Tranny as in the FX50, it will handle a LOT more power than the old 350Z's AT (which sucks monkey balls for power handling).

I havent' test driven 6MT but I was also a bit disappointed by 7AT. I am test driving another auto this weekend along with 6MT and will report back my thoughts. Did you feel less power with the auto?

damn good thing i got a Z then. i guess just because i own one i can shift SUPA FAST.

sbkim

Terribleone - how does 370z compare to your G37? I presume both are manual?

Thanks!

Guess we will see.... And I was not talking faster around a road course. The MT better be quicker around a road course.

I was talking straight line. I still think the AT will have the advantage there.

Actually, the auto now has a multi-disc (5 I think) 100% lock-up torque converter. The power loss through the drivetrain will be less than typical. I suspect a 7HP difference between the MT and AT. Nobody has dyno'd the AT yet, though. The reason there will still be power loss is that an AT has a lot more spinning mass. So the manual will be more efficient, whereas the the AT will have the better launching gears... In addition, the AT has the ability to torque up. A manual CANNOT do that without a transbreak.

The AT will be faster in the quarter, I'm about 90% sure on that. I race both AT and MT and I'm pretty confident that with the ability to launch with torque already at the wheels and the limited amount of power drain through the auto, it should be a quicker run. I can shift a car in the 300ms range without a problem. I look forward to power shifting the Z and seeing how fast I can REALLY get it to run the 1/4, so I really think it will come down to standard MT drivers being slower than the AT, and drivers that SLAM and power shift will be faster than the AT..

On the freeway, the MT will likely win. That 7th speed doesn't help with the gear ratios, and the final gear on the MT will make a huge difference. Control is everything though. It may be down to the drivers.

I agree.

Given the fact that 370z is pure 2 door sports car, I cant even imagine driving it in automatic. If this car is lambo, Ferrari, or even BMW M, I can understand (but, I would still get manual for these cars..lol)

I would like to get most out of this car, drive the way it was suppose to be, and thats by manual, Syncro-Rev style!!!

Remember, Don't let the car drive you, Let it be Driven by you..

Guys, these are just my personal opinion, so no offense meant to auto 370z owners. I just want prospective buyers to consider test driving both manual and auto before making huge decision...

Endgame

Decision 99.5% made.. 7AT

I have been driving manuals all my life and currently have my first auto with paddle shifters. They have provided nothing but fun for me all the while being convenient. In fact my current vehicle has been my favorite car up to date. And I'm sure the auto will be just as fast if not faster up to triple digit speeds making this an even easier decision for me. I am officially done with manuals....unless I decide to pick up a Viper in the near future.

MT is another sensation, using the cluch = more sporty

AT is diferent the sensation, but improve in the aceleration = more quick

Well I didn't get on it too hard, but obviously the engine is the same so it felt about the same, just boring and distant.

I guess for me it isn't all about having the fastest shift on the block, I enjoy the involvement and connection with the manual, even if the auto shifts a tiny bit quicker.

I would never buy a Miata or Z with an auto, and I would never buy a minivan or SUV with a manual. To each their own I suppose.

I'm going to test drive both this weekend, but here's my question. Maybe you (or anyone) can help me with this. I've also driven manuals all my life, but this time I wanted the paddle shifters. I know this isn't a DSG like in an M3 or an Audi, but I want to know if it will ever interfere at all. If I'm using the paddle shifters, will it shift for me at some point? I don't want any interference, I want it to shift up or down only when I do it. Is that possible in the Z, or do I need to stick w/ the 6AT? I know with the DSG cars, it only shifts when you tell it to, other than going back into first when you come to a stop.

Thanks.

sbkim

Can anyone confirm whether 7AT starts in 2nd gear from dead stop - depending on throttle position?

Endgame

I would imagine the 7AT only shifts when you want it to, except going into first upon near stop. Most sport ATs do this now. Heck, my wife's CX7 6AT does that...
