Haldex 4 v's Torsen diff/Quattro?

Can somebody make a little movie clip of the Yeti losing traction in snow/ice so we can see how soon the rear wheels get driven?

It sounds like the 4WD computer program is in Blue mode for the Yeti - ie, running pre-emptively which would be better than reactively...

I was thinking of I would get the Blue/Orange change to the 4WD computer software somebody mentioned to ensure 4WD was always active when driving in winter, but perhaps that's not even necessary! --somebody post a clip of their Yeti 4WD operating in snow please - we need a definitive answer on this one!

I'll pop outside and give it a go but having played with it off the line on ice and snow recently - to me at least, it feels like a permanent 4wd setup compared to Gen 2 Haldex anyway. :yes: (I know its not actually 'permanent' btw)

  • This thread might be worth a read: LSD/EDL Haldex is a genuine 4x4 system. More and more 4x4 vehicles are moving to haldex like systems. The Q7 uses the BorgWarner system I believe. The other major

  • I still remember with suppressed fury the tagline when Audi first launched the Q7: "It's what quattro was invented for". No it wasn't! When it was introduced in the 1980s the Audi Quattro was almos

I beleive that Gen 4 pre-engages the rear wheel when at a standstill, then dis-engages once you are under way (conditions allowing).

Well Ive been having a very good 'play' on what can only be described as an ice rink :rofl: Whether its from standstill or when moving in second gear there appears to be no traction loss from the front before the back axel comes into play!

I have some footage - just need to work out how to edit .mts files, convert them and host them somewhere.

I've had no reason to do that but this might be an option for you. http://www.squidoo.com/mts-files

Summer tyres perhaps? :D :D

Summer tyres perhaps? :D :D

yip quite definately but also someone who isnt very wise at driving lol

Not sure if

answers the question or not!

Right at the beginning of the film, the fronts definitely spin and after a moment, the rears then start turning. But in the next start, all 4 wheels begin turning together.

Still, it's an interesting bit of film, though I have to say, there was some pretty expensive stuff to hit in the background if they got it wrong!

Hello, everybody :) 

I am new to this thread and just wanted to answer this great forum members question 7 years later. 

I currently own a 2011 Audi Q7 Diesel, 2008 Subaru Forester and 2010 Ford Escape. Yes, Audi Q7 stock tires suck in snow to make matters worse they are pretty much the only tyres you can get. So wide low profile summer all Seasons is what your stuck with, unless you get crazy expensive with some Blizzaks.  Currently at least where I live, there is not BF goodwrench trye that will fit a 20" rim and low profile tyre . Plus the Q7 is a super heavy 5,000 lbs heavy, lastly it's a 40/60 torq starting point with rear bias. Meaning, yes on icy roads on inclines in my opinion it is the weight of the Q7 that just kills its along with the crappy tyres on snow that doesn't help either. The Subaru will do absolutely way better in that situation, hands down end of story no drama will do it or it won't 100% or zero percent with Subaru. The Hybrid ford will do better as well as that uses a Haldex AWD. Why would I dog Audi Q7 in these situations? For two simple reasons in my opinion from driving them all in snow and ice. Front wheel drive bias vehicles will always do better as the rear wheels need to just help a bit to get the fronts to grip. Plus the fronts have all the weight of the motor on them. Think of this, you and your 6 year old kid have to get a loaded sled up a steep incline. Subaru and Ford, put the adult in front pulling (metaphor) while your kid pushes. Clearly he isn't doing much, but just enough to allow you to keep your footing and traction to pull it up. Vice a versa , if the adult was pushing and the kid was pulling the sled, if the adult slipped or lack good grip to sufficiently push with sufficient force then all the responsibility falls onto the 6 year old and you all slide back a bit. This was just an analogy to illustrate a point, not a technical explanation hence a metaphor. Torque both Subaru has Ford are around 150 ft/lbs vs 400 ft/lbs. Obviously just watch F1 and you will know that too much torque delivered to quickly will make your tyres spin, that is why Hamilton and the rest, shift to higher gears as quickly as possible going out of corners so they can  lay down 100% torque without spinning out. Given the Q7 makes 400 ft/lbs at 1750 rpm, the quick delivery of turbo torque on slippery surfaces, it just a bad combo in my opinion but were talking about physical characteristics. A playboy model girl friend will always be awesome, expect going to church with your parents...   Then you want the homely good girl next door to be with you. So why is Q7 better then Subaru and Ford ( I live in the USA so no Skoda :(   )? Prestige and brand recognition, it drives better, it's faster, it rides better, corners better, accelerates better, gives a better impression, styled better exterior, interior isn't cheap looking painted plastic and it's timeless. It will always be an Audi regardless of how old it is, while my other cars. Well they will just be "paid off" so that's while I like driving them and they do great in the snow. Oh one last things, nasty off roads where you really have no business bringing anything then a 4x4 truck or Landcruiser Audi will absolutely destroy the Subaru and Ford. As you mentioned wheel spin, going up rocks, loose gravel and shear pain, the Q7 just keeps punching until it gets through that mother.... Subaru just stops, literally it's like over the hard part and the ESP says. "Sorry mate, to much for this car, so let's call it a day". I have been stuck 95% up a hill after the apex where is just like gravel on the fronts and the rears are in a rut and the Subaru literally shuts the car down, WOT nothing. Ford, just starts spinning one wheel in the back while the fronts are spinning out from lack of traction. Q7 you hear the wheels churping and smell rubber burning and hear the EDL getting crazy then the crowd cheering as you made it up. Then you open the door to get out in your suite and Edmond Allen shoes and then people realize why Audi is so cool.  But in reality i think Range Rover sport is better then all, but I just can't afford that much of a car so i went with an Audi.
