Torque Steer

[jezitalia]

Hi Guys,

This topic came up on an unrelated thread.

I get it badly when overtaking.

I am on 21's with the One tyre i did not want on my car, the Dunlops. Had them on my C6 and then changed to Michelin Super Sports, much much better.

Question: does anyone else on Dunlops get this, any comments from P Zero or Conti shod car owners.

I just wish the Michelin SS's were homologated for the C7. They have the right tyre and spec all bar the magic R01.

[jezitalia]

quick comment just asked the stealers if they have had any feedback on this issue. will report

Have exactly the same problem on Dunlop's, very disconcerting at 1st!

now starting to wonder if this is a problem with Dunlops-I posted on another thread that I very nearly lost it not long after I took delivery of my C7,see New Beastie Ready,never experienced torque steer before,had a B8 before the C7 and never had it on that car,almost too scared to hard accelerate now. surely they must have tested these tyres before deciding or did they just buy a job lot !!!! I note a poster who said he is Contis
and has never experienced it on his C7,so this must pony to the tyres? No??

No issues at all on the conti. Been doing a lot of launch controls recently and not a thing. Straight down the line.

Same here, I'm on the conti's and no issue with torque steer. I've given it a few launch control starts and just general pulling away enthusiastically all good so far.

I also have Contis and there might be the occassional very mild sensation of torque steer but not enough to be an issue. I did a few launch control starts last month and did not notice anything worthy of note regarding torque steer. What suspension are those who are experiencing strong torque steer running? Car can pitch a little on air if you don't run it in sport- this would tend to upset front suspension geometry...that said it should unload evenly though.

It's been quite awhile since I sold my C7 but it is quite annoying to discover that the torque steer may well have been caused by tyres. I just assumed it was a mechanical. I experienced the problem a few times but one in particular where, if I hadn't have caught it in time, it could have ended badly. My car had the dynamic pack, not air.

[jezitalia]

I run mine mostly on Auto setting, today took it out and ran in Dynamic, still felt it slightly.

Connecting the dots of C6 mild sensation on Dunlops and the Conti users replies, I am seeing this as tyres.

I think some feedback is going to flow back to Audi. First via Stealers, secondly to AUK, as this is seriously diminishing my enjoyment of the car and is not as it should be.

Why don't they get the Michelin Super Sport homologated and set up with R01 fitment, they have the size and loading all there.

Like I said I another post. I'm on conti''s and no problems here. I run my drive select as follows
Gear box : comfort
Air suspension: auto
Steering: comfort
Diff: dynamic
Exhaust: dynamic
TBH. I've always hated Dunplops. Back in the 80's I had a MK2 escort RS2000 and I nearly died coming off a roundabout and was caught out in a big way. The car had always run goodyears previously and Id always drive it like I'd stole it as you do when your 18years old and stupid. But a set of Dunplops came cheap and they were the worst tyres I'd ever had and to this day I would never touch them with a barge pole. It was the same again when in the 90's I bought a Series 1 RS turbo and it had Dunplops D4's on it so I went straight to tyre sales and had goodyears fitted.
Ps my brothers and I nicknamed them DUNPLOPS cause they are just plain sh1te.

I posted on the other thread about this. I experience a form of torque steer quite badly and with complete repeatability - but it isn't torque steer in the form of the old FWD hatches, which shows up in a straight line (so you won't see it doing launches). I am on Continentals.

The only time I experience it is in overtaking which combines sudden changes of direction with full throttle acceleration, I don't ever mix the two in normal driving (such as along a winding country road). If I accelerated hard as I am pulling out then the car fights to stay put in the left lane. Accordingly, I find it better to pull out and then accelerate. It also happens, of course, at the end of the maneouvre, when I want to pull back in. If I am still accelerating the car fights to stay put on the wrong side of the road. Again, I need to ease off unless I want to wrestle it back. It's not pleasant!

I am interested in Eddie555's setup with the suspension and diff. Maybe that will help. It certainly seems the car is better behaved in Dynamic than Comfort, but I don't want to spend my life in Dynamic just on the off-chance of an overtake. Perhaps AUTO for some settings will sort this out.

Gear box : comfort
Air suspension: auto
Steering: comfort
Diff: dynamic
Exhaust: dynamic

Thanks for these settings. going to give them a go (as mentioned in my post above). One interesting thing. When I got the car, I had everything set to Comfort, except the exhaust, which I set to Dynamic. I did a long motorway run and get rubbish fuel consumption. I then turned the exhaust to Comfort and did the return trip - I got much better consumption (an extra 4mpg). I haven't repeated the experiment to confirm, but it seems that the exhaust setting may affect fuel consumption quite significantly. It's great having the sports exhaust "on" whilst on a cross-country blast but it adds nothing aurally to a motorway trip but still might be costing fuel.

[jezitalia]

Wildbore, the sensation you describe is the same as I feel. This is simply not right for a car of this type, value and supposed superior Quattro handling. After all this is and has been Audi's big selling feature- Handling.

Interesting you are on Conti's and have the same issues.

I am going to keep the pressure up with Audi as this is not in my view how this car should handle, whether it be Tyres, Torque vectoring ( i.e. searching for grip = more front power = Torque steer effect? )

I run mine usually with:

Steering: Comfort.
Suspension: Auto.
Gearbox: Dynamic ( effect happens in D and S mode )
Exhaust: Dynamic.

Funny you mention consumption and settings, best I have seen is 27.5mpg on sedate motorway run on Comfort mode!

forgive me if it's a stupid question but if it happens when you pull out to overtake is it not one of the active safety systems cutting in like Active Lane Assist trying to stop you changing lanes so quickly (I do not know how advanced these systems are now, I remember when they first appeared it was just a vibration under your seat if you changed lane without indicating but I imagine with all the automated safety systems now it is much more clever and more intrusive).

[wildbore]

No, it's not safety systems intervening - although it's not a stupid question, it's a very good point, and I did find I was fighting both Lane Assist and Side Assist once when I went to do a quick maneouvre on the motorway. After that, I learned to switch off Lane Assist as soon as I deactivate ACC.

It's definitely a form of torque steer - under full acceleration the car doesn't seem to like sharp changes in direction. In one way, that's fair enough. it's a lot of torque being put down and some of it is through the front wheels. It just seems that the car shouldn't do this, it should be more precise and controllable.
