ACTIVE STEERING.. confusion

THERE IS NO ACTIVE STEERING ON THE M3...

Servotronic "varries the amount of power assist"
and does not change steering ratio...

my question makes sense for someone with active steering..
((at low speeds you have to turn the steering wheel less.. so a tighter turn takes less turn angle..

at high speeds you need to turn the steering wheel more... so a lane change aquires more angle...
--i guess the only way to descibe why is there is less "percent error"?? in your steering at high speeds.. (a slight accidental tug is not going to have as large an effect..)

so now my question.. when its off how is it set..
-1-are the high speed turns the same and low speed now requires more turn angle..
-2-are low speed turning angles the same and now high speed turning is tighter??

... i ask because if -1- is true then it is smart to keep active steering ON because it makes life easier
-if -2- is true then in performance driving i think i would want it OFF as i would rather the tight steering at higher speed... ))

..what a waste of time thinkin about that..

There is no confusion here, as there is no active steering in the E9x M3.

Correct me if i am wrong:

at low speeds you have to turn the steering wheel less.. so a tighter turn takes less turn angle..

at high speeds you need to turn the steering wheel more... so a lane change aquires more angle...
--i guess the only way to descibe why is there is less "percent error"?? in your steering at high speeds.. (a slight accidental tug is not going to have as large an effect..)

-if -2- is true then in performance driving i think i would want it OFF as i would rather the tight steering at higher speed...

Hope i didnt confuse the sh*t outa anyone..!
do i make sense.. (i just cant see having a looser steering at high speeds a positive)

+1

But I'm sure after about 5-6 posts on this thread, someone's going show up and ask how the active steering feature works on the M3, or state that he hates the active steering on the M3 because minivans can outsteer him.

It just varries the amount of power assist, not the steering ratio.

Hi have Active Steering on my X5 and you have to remember how it works when you go from one car to another. When you parallel park in a tight space and turn the steering wheel to much you hit the curb with edge of your wheel rim.

My wife is getting good at giving the front wheel a good smack on the curb!
