6MT vs 7AT and the Track/Auto X

Endgame

Sorry Kannibul.. I mean to type the Z's 7AT shifts FASTER!! My fault... But, my wife's CX7 acts just the same.

I am impressed that the Z's tranny shifts SO fast when copared to the other modern 'Sport' At's. However, I have my doubts that it would be good on the track/autoX.

And for good reason. I don't know of any automatics that are used with any kind of frequency for "events"

That being said, I'd be confident the 7AT would perform as well, and possibly in some ways better, than a 6MT.

Short of overheating issues...if that's an issue (comparatively speaking, regarding oil temps vs transmission temps - which one becomes an issue first...)

Again, Car & Driver reported that the 7AT does not drop 2 or more gears when requested. I've never driven the 7AT, so I have no fkin idea............but C&D's take makes me think it would suck in AutoX.

Quote: "The one negative we noted was a reluctance to crack off seamless multigear jumps. Call for a two-gear drop, and the engine briefly hangs up on the first before dropping into the second, sapping some of the joy and confidence from quick two-lane passes."

That pretty much sums it up right there.

That's Car and Driver. My experience differs.

It won't jump gears, except from 7th to 5th, when bumping the paddles or kicking the stick over from D. Otherwise, it is sequential, but still quick. Certainly not F1...

Come on ... the Zs A7 is good - have you ever driven a real modern day sequential? There is a HUGE difference - stop fooling your self about it... but if it helps you feel better then w/e

awesomez

Or are you making yourself feel better by belittling auto

shabarivas

Hah... so the serpent has come full circle to bite its tail eh... ok ok... you do realize I was Belittling the "auto" compared to a SEQUENTIAL... you understand the difference between a manual and a sequential? please dont make me tell you to go look it up @ google... oh wait.. i just did

Lets say this about the MT / AT debate

1. With AT you get the same shift time every time and you cant really improve upon it by being a better driver (hardware limited)

2. With MT - its you who are limiting the cars shift speed - so you can do it as fast as the mechanics allow and the human element is often much easier to improve over time. Which is why MOST experienced MT drivers will shift faster than the Zs AT

Easiest way to put an end to this silly debate - Get a MT and AT z on a dyno... shift and watch the curves for which has more delay... obviously we would have to use a "decent" MT driver... but hey - it would be better than my opinions vs yours....

In fact there are two things: science and opinion;
the former begets knowledge and the latter ignorance

kannibul

When I say sequential in regards to the 7AT, I mean you go from 1/2/3/4/5/6/7 - you don't skip gears, except when moving the auto-stick over, it'll downshift form 7 to 5. If you hit the + paddle with it in D, it'll just stay in 7(M), then you can move it to 6th, 5th, etc in order.

When you say modern sequential, I think you're talking about a dual-clutch, servo-operated manual. Huge difference, and not something I am trying to compare, other than they both operate in sequence.

Hmm... I'll have to pay more attention, but that's not really the feeling that I get; it seems pretty seemless to me.

As someone who has driven both manuals and automatics, I think there is a little bit of "Back in my day we walked five miles to school!" style thinking when it comes to glorifying manual transmissions. Does anyone really think manuals will even be an available option twenty years from now? Five years ago I would have been in total agreement with most of you, but it seems like we are at the point where automatics are catching up to and possibly surpassing manuals.

Great post. I take the opposite tack with the lifecycle of manuals, though. In twenty years I think a stick and a clutch pedal will be an option, just as it is today. In Europe they still scoff at AT's unless it's on an F1 car, then of course it's ok.

In the US, the AT rules since the US is so auto-centric for commuting as opposed to EuroAsia which is public-transport-centric for commuting. In the US, the rush-hour traffic jam is a fact of life that begs an AT. In Europe it's like 'ok it's Saturday let's take the Carrera out for the day'.

The Manual Transmission/Clutch Shall Endure. I hereby decree it.
