Winter M driving

How many M drivers will be using their M over the winter months? I'll be out in mine quite regularly...love the ability to slide the car around a bit at low speeds (even with the TC left on). It's not the quickest car to drive on these slippery roads, but certainly quite a bit of fun.
 
I thought this 'traction control' confusion was sorted last time when it was agreed that the Z4m does have traction control, but it can't be turned off in isolation to the stability control (except by coding) :?

The Z4m does not have a 3-position (all on, TC off, all off) system like the non-M cars - we just have the 'all on' and 'all off' settings, and the DSC system controls both the Stability Control and Traction Control at the same time. So the Z4M 'all off' setting turns off BOTH the SC and TC at the same time.

I know I can still get mine sideways, and break reaction with everything switched on though - just have to be more clever/abusive about how you do it :oops:
 
In any case I'll certainly be using the Z4. I'm trying not to put miles on it, but I'm rubbish at that.

My 645 was much trickier in the wet/cold - auto box, no LSD, 330ft lb of torque at low rpm, huge rear tyres.
 
You would have had fun around here this morning. I pulled out at one T junction (DSC on, Talent Off) & tried to gun it. Much opposite lock was still required. :driving:

I love these cars. :thumbsup: :D
 
Our traction control is called a LSD which is mechanical and cannot be switched off. That's how I see it.
 
I got stuck around sheffield in the snow in the M3 yesterday, v8's are expensive things in traffic jams.....although it was great fun around scarborough in the evening :driving:

The LSD is not traction control. It can send power to the wheel with the most grip, but it cannot cut power from the engine as the traction control system does.

The electronic M diff on newer models may have traction control functions, but not the Z4M's basic mechanical one as far as I know.

The Z4M supplement booklet says that we don't have DTC, but the DSC system controls wheel spin when accelerating by cutting fuelling/power. As you say, there is no separate traction control system, it's just part of the DSC.
 
Haha. Thread de-railed as usual :lol:

Won't be driving mine much this winter I don't think. Saying that, the odd blast will be good :thumbsup:
 
I like the LSD. This isn't the first car I've driven with one, but it is the first car I've owned with one and therefore the first car I've pushed hard enough to feel the effect of it. I like it.
 
I think Srhutch was perhaps being tongue-in-cheek about his t/c description of the LSD... as he points out an LSD and winter tyres and you can go anywhere if you know how to drive :wink: https://www.youtube.com/watch?v=BSrE4E8Gkos#t=48
Winter rims and tyres on since last month, need them round where I am. Use it all the time :driving:

Exactly we have DSC the same as lesser zeds which I believe is exactly the same in it's function. The LSD negates the need for TC in lots of ways hence why we don't have a TC button.

For the last three winters I have had winter wheels & rubber on my Z. This year I haven't got any and I have to confess to being a little nervous. Though the amount of snow we get here is negligible, so it's really just ice I need to worry about.
 
As a new (two weeks in) roadster owner, I'll just leave this here... 9am this morning;
