Thought this was quite impressive:

I wonder if the engine temperature was going up with the grills blocked with snow.

I hope this isn't you know who again..??

Doubt it, he's been around since 2007!

I'd just rather not have snow.

Only 2WD but it would be interesting to see how the winter tyres perfom.

I am actually really looking forward to trying out the Vector 4 Seasons I have recently fitted in the snow. I think that - combined with 4wd - they should prove to be an excellent solution for winter conditions over here. Will report back with pictures as soon as I have ventured out to the mountains and tried them out.

Let me get this straight about the rear diff. As I understand the Haldex info, the centre diff & rear prop shaft are turning all the time. The prop drives an oil pump in the rear diff to generate oil pressure to operate the clutch. The clutch is engaged when the electronics controlling ABS, traction control etc. detect a loss of traction at the front end, enabling four wheel drive. When the traction issue has been resolved, the electronics drop out the clutch. As I read it from the Haldex info, the rear clutch is either in or out, nothing in between to control torque distribution, as this would wear out the clutch pretty quickly. I can't see how it can be said that even under normal conditions that maybe 5% of torque is going to the rear, as this implies either control of the rear diff clutch, or some form of proportionating of the centre diff to split the torque. As far as I'm aware, the centre diff is a fixed ratio & is not controllable in any way. Anyone care to enlighten me if that is/not the case?

An explanation of the voodoo that is 4 motion, quite a good clip this and explains it well, also how the percentage of drive can be split and not just on or off.  I believe the drive for the oil pump is electronic and not driven from the prop. Here is a Haldex unit detached from the differential and shows the electrical connections.

 

 

 

Sorry Dinger, but you are wrong.

The Haldex is able to infinitely vary the amount of drive it puts into the rear axle.

This is even mentioned in the Brochure for the Yeti.

and shown in the youtube clip above.  It really is an advanced piece of kit that works extremely well on many cars across many brands.

And this is the new gen 5, fitted to the FL yeti

Not sick, just adventurous. Find an empty field or car park somewhere & discover your & the car's limits. It's great fun. I've driven mine many miles in snow (we can get lots up here in the Scottish Borders), with a set of winter tyres without any problems. Best advice I can offer is to stay away from the brake pedal, reduce speed by slowly easing off the gas & using the gears, changing slowly & smoothly. In very icy conditions, ABS won't save you, but the traction control might pull you out of a sticky situation. Just wish there was one thing fitted & that's an indicator in the dash to tell us when the rear diff is engaged. Don't need fancy graphics with torque/power splits or the like, simple on/off indicator would do. Anyone else fancy suggesting that to SUK?

When the real snow does arrive, enjoy, & you'll soon be asked by friends & neighbours how it performs, don't forget to ask your local Skoda dealer for your 10% cut !!!

 

My friends and I did this when younger in empty industrial estate car parks as soon as the snow landed.   Messing about in fiestas/astras/cavaliers with no fancy ABS/ESP/4 wheel drive/ winter tyres certainly teaches you about car control! :peek:  I can state categorically that it has saved my insurance premium on numerous occasions. Knowing what a car is capable off and how it feels when about to lose control makes you a better driver imho.

It does not seem to matter how much you know how to drive in snow, its the other numptys on the road that have no idea. Last year i got stuck in rush hour snow in Newcastle and the only way to get home is up one of 3 steep banks, it took me nearly 4 hours to make the 8 mile trip home and most of the problem was other drivers just driving in exactly the same way they would do on a summers day. People were pulling right up to the back of your car on a steep icy road and then looking in shock when cars were sliding backwards into them when they could not get traction and the idiot behind had only left 10 cm gap.

Yes, not only is it great in the snow, it's also great in high speed road based situations too!

 

It really is a great bit of kit.

Must be a company car!

 

No Briskodians I know would treat their car like that!! 

Many thanks for all the Haldex info, the muddy waters are now clear.

I am regularly off-road in mine, usually in the forests of North Yorks, Northumberland, Borders & as far north as Inverness when doing Rally Radio on the Snowman in February every year & neither this one (2012 MY 62 plate) or my previous one (2010 MY 10 plate) have shown any inclination to dive into the waiting ditches. On the Border Counties Rally in March this year, loads of snow, but with Nokian WRG2 205/60/16 rubber fitted on 16 inch Superb rims, no problems getting around.

Thanks to Llanigraham, Worcester 1, MSA radio, maybe catch up with you some time if you ever get this far north. Keep an ear out for me, TOB 26.

I don't usually get much further south than N Yorks or Warcop for the Pendragon Stages, it's getting expensive to cover rallies these days, but there's not much to beat stage rallying, either in the woods or on the army ranges.

Again, many thanks for the info.

Rubbish!

It's a 4x4.....use it!!

Ahem:

 

Got a bit carried away with the winter tyres on my Passat, boshing through small drifts, didn't spot what a monster this one was though in time. All my own fault.

Is there a redface smiley on here ?

 

Farmer was amazed how far I'd got though we he came to drag me out with a tractor....

Whilst I'm aware the trouble caused by snow to the emergency services I would still like to experience one or two days of it if only to vindicate my purchase of winter tyres. Does this qualify me as a 'sicko'?   :think:

Of course some of us are members of a National voluntary organisation that helps thses groups when the weather is bad.

See the large type below!!
