Does the ZF act like DCT at a stop???

Does it act like a normal automatic at red lights where the car will move forward unless you are on the brake?

With the DCT at red lights, it would somewhat allow you to blip the throttle a small amount before the clutch's engage. Does the ZF act like that? Or is it like a normal auto in a family car that just jumps forward the second you barely touch the throttle.

I recall reading somewhere there is a feature to have the car move forward by 1-2 mph and it requires you pressing the brake and throttle (could be mistaken) - I will see if I can find that info.

That being the case then I would guess it would remain completely stationary if you are not pressing the throttle.

I haven't driven a BMW with ZF so can't say for sure.

EDIT: Found what I was referring to, it's called the Low Speed Assistant, see excerpt from owner's manual:



So it seems like if you follow that combination, then yes the car will move forward in 1st and 2nd gear, but if you don't do it, then it remains stationary?

Maybe someone who has a M3CP/M4CP can comment

I think I might not be asking this correctly. Let me try it this way...

Think of how a centrifugal clutch acts. The DCT somewhat acted like that from a dead stop. You had like a nanosecond to blip the throttle before it started moving forward. So if someone was staring at there phone at a red light, I could quickly slap my throttle and my car would rev like a 1000rpm up and NOT move forward INSTANTLY.

In a normal everyday auto, if you let go of ther brake, you are moving forward and even if the car has auto hold, once you blip the throttle you are MOVING.

So DCT's centrifugal clutch like feeling gave you nanosecond to rev your motor. Which I like. Most normal autos DO NOT act like a centrifugal clutch/DCT feeling.

Know what I mean? And thank you none the less even if you dont own one! = )

Ahh I know what you mean now, my previous 2 cars were F83's with DCT and it did exactly this. I used to like this too.

No clue about ZF as I never driven one, let's see what others have to say!

This coming from my X3MC which is same setup... you can't blip the throttle. However, it does behave interestingly in that if you just take your foot off brake and do nothing, it doesn't crawl for a couple of seconds and feels like it is disengaged. I actually really like this feature. No matter, when you touch throttle it is quickly responsive, twitchy even if in sport plus. If you take foot off brake and don't touch throttle, it will engage and start to move after a couple seconds.

Yes there is torque converter creep. It's not as pronounced as some automatics that will take off when you let off the brake.

There is a button on the console (I forget what it is called, but use it often) that when engaged will allow the driver to take his foot off the brake and it will stay at the point of stopping until the gas pedal is pushed.

I'll check when I get home tonight and attach a photo.

Thank you, but that's not what I meant to ask.

DCT from a stop acts like a centrifugal clutch. To where you can quickly blip the throttle and throw a small rev before it engauges and goes.

At red lights where the guy in front of me was staring at his phone; I would blip my throttle in a DCT car and get his attention. I would NOT roll forward and take off. As long as I was quick with the blip and not too much.

Where as normal automatics.. the second you left off the brake, it rolls. Now I know BMW has HOLD Assist. Which is to hold the car still until you press he gas. But thats not what I am talking about.

I just wanted to know if the new ZF acted like DCT which acted like a centrifugal clutch from a dead stop. It seems that the new ZF does not act like DCT in that sense.

It is a standard automatic with a torque converter, it creeps.

Yea that part sucks. Going from F80 to 4 911's has me all for DCT/PDK. The lack of competition model with X drive in 6MT blows too.

It's a torque converter automatic transmission. It's a good one but that's what it is. It is not a DCT and doesn't behave like one. The era of the DCT is over.

If you have that on it won't creep? Does it stay on or does it turn off when you hit the gas?

It stays on so that when you press the break at the lights the car doesn't creep

You don't need to press it each time

Does it also light up "PARK" on the dash as it uses the parking brake?

yeah it does. i use this feature all the time on my x3 but as you said, it is an automatic application and release of the parking brake at a stop, it is definitely not replicating the feeling of the clutch engagement of a DCT.
