In my experience with the r56 and the stiffer chassis, under hard acceleration while turning, the inside wheel off-loads and starts spinning faster than the outside wheel. when it re-gains traction, it'll pull you in the same direction hard and if you ease up on the throttle, you can expect a lil' more excitement than you bargained for

same can happen on un-even or bumpy road surfaces while accelerating hard or at high speed, which ever wheel off-loads, the car will pull to that side, being right or left..

Too bad eliminating torque steer was not as high on the priority list for the new minis as it was for the older ones. It's such a near perfect car in so many ways.

I have yet to drive a front wheel drive car ,that did not have torque steer

as far as I know, there's no way to remove it

it's the only thing I do not like about mini's

What you describe can be dangerous or not?

maybe, but EVERY front wheel drive car has the same problem

That could be adjusted by the drivers input, keep the wheel spinning a little longer out of the turn till your on straighter ground. you wouldn't feel the jerk as bad cause now you are heading straight not angled as much.

I have never experienced torque steer in my '07 MCS. I can gun it from a dead stop with hands of the wheel and it will go straight as an arrow. I do have a limited slip diff. At various times I've disengaged the DSC and then I do feel some torque steer. I've had the car on the track at Sebring in FL and never had a second's worth of torque steer, even when the wheels are turned and I was at full throttle.

something is wrong with your car then, or your not driving it hard enough

exactly I test drove one and it supprised me.
It wasent unmanageablle but it took away from the fun factor.

Puh leese, I know what I'm talking about. If you want to come to Florida to drive it you are welcome to do so. There is nothing wrong with the car and driving at Sebring is certainly driving it hard enough. Red line in every gear except top for about 40 laps total. There is NO torque steer.

you may not know what torque steer feels like then

Listen pal, I've owned a few front wheel drive cars, one probably before you were born. I know what torque steer is. I had a 1974 Fiesta in 1974. It was the worst torque steering car I've ever owned. I also had a 1992 VW GTI which also had some torque steer. I'm 67 years old and have been driving for over 50 years. I don't know everything but I do know what torque steer is. Come to Florida and drive my Mini.

I think if investigator is doing hot laps at Sebring, he'll know torque steer if he has it. That track will bring out just about anything there is to discover in a car's characteristics, strengths , and shortcomings. I've driven a couple parade laps (i.e. 60 MPH) at Sebring and that was enough to convince me how revealing and technical a track it is. There are plenty of corners to expose torque steer problems on exit.

They say, if you want to win Le Mans you have to finish Sebring first. Peugeot knows that be experience this year.

Why run the R56 In stock configuration it wont pull much faster than 5500
Thats about all it wants. nothing wrong with that though.
Just Fyi No one cares how old you are. If you dont know that when the wheels twisting out of your hands under power its tq steer you got larger issues.

Mayb e you ought to read my first post re torque steer. Under full power, hands off the steering wheel, from a dead stop, NO torque steer. Please don't reply again because this is unbecoming with no pithy comments from what I thought were intelligent people.

I guess you had torque steer but now you dont

you dont think something is wrong with your car?

If I floor my car (ALL the way to the floor, you said you did not) I get torque steer, pretty bad, as soon as the front wheels start to spin it gets worse

I've driven cars LOTs worse, but ALL front wheel drives have it

For straight line acceleration its all a question of balance. Quite possibly, (although not very common) if everything is just right the torque to both wheels is perfectly symmetrical. Since MINI at least have equal drive shafts, you at least have a chance that the friction, and all other factors are equal to the ground for both front wheels. When this happens you have virtually no pull, until something changes - a turn for example would really upset that balance. Hope I don't get dinged for plagerising but there really are some good explanations others have pointed out:

Torque steering

From Wikipedia, the free encyclopedia


Jump to: navigation, search
Torque steering is the influence of the engine torque on the steering for some front-wheel drive vehicles. For example, during full acceleration the steering may pull to one side, which may be disturbing to the driver. This either causes a tugging sensation in the steering wheel, or else the car veers from the intended path. As the torque steer effect is directly related to the engine torque capabilities this problem becomes more and more evident with high output engines with strong low rpm range torque.
Torque steering may be confused with steering kickback.

Causes

Root causes for torque steer are:[1]
  • Incorrect sidewall ply design allowing deformation of the tire sidewall.[2]
  • Nonsymmetric driveshaft angles, e.g. due to
    • Nonsymmetric design of the vehicle, e.g. different driveshaft length
    • Transient movement of the engine
    • Tolerances in engine mounts
  • Different driveshaft torques left to right
  • Suspension geometry tolerances
  • Unequal traction forces due to road surface (µ-Split) in combination with kingpin offset
  • Open differentials may not equally distribute the torque between the two driveshafts, due to friction in the side gears etc. The same will be seen if a limited slip differential is used. Either way there is a tendency for the slower wheel to receive more torque.

you would be that person, the wiki info confirms what I said

it's physics 101, if torque is transmitted though wheels that can turn, you will have torque steer

If torque steer exists then my open-diff auto MINI has it. A lot of it! Gobs and gobs of TS. I don't think it's a bad thing. Keeps you on your toes. If you don't like it don't accelerate so much with the wheel turned. Otherwise the steering wheel can counter TS pretty well.

Hah ha, well that would rule out tracking the car.

I'll see how my 09 JCW does. The MCS with JCW I test drove had torque understeer when turning left, but that's all I noticed. Seemed fine in a straight line.

Investigator, from what I remember running Sebring in a Boxster, I do not think my Mini would have torque steer there. You can carry enough speed through the corners that the acceleration is not violent enough to cause TS. However if you are going about 20mph in second gear and quickly turn the wheel while punching the throttle you are going to have to hang on to that steering wheel! I suspect that it is because the torque in the 1.6 turbo comes on so rapidly and at such low revs. I think the torque in the R53 just came on a bit more slowly which is why it had less apparent TS.
