But, I can see why it would be hard to tell given that the amount of assistance is also changing. IOW, while you can tell something is going on, it would be tough to determine exacty what it is.
I will have to check again, but it sounds reasonable that the steering ration does not change, just the power assist. Then again, the power assist makes it possible to park the car with your little finger it might be this that fooled me.

I ordered the Tech package today, I was debating it for a little, but I do want the ability to adapt the car to my style and for resale value.

I am quite convinced that MServotronic only varies forces (level of assist), and that MDrive changes the way in which those forces vary.

What am not convinced of is that, seperate from that technology, the ratio of the steering is not also varying.

Not that it matters at this point, because that would not be effected by MDrive one way or the other. So we are basically OT. But it has now become a big curiousity of mine.
As the M3 aftersales training told us the M3 is not available with active steering. So the Steering ratio doesn't vary, it's fixed at 12.5:1.

Best regards, south

Well, I do agree now that it is fixed, south.

However, I don't agree that the lack of the presence of the technology branded as "Active Steering" in this car directly implies that the ratio does not vary. Active Steering includes a variable ratio, yes, but also (and perhaps more importantly given the "active" description) the car will steer for you under certain conditions. In other words, BMW could use a variable ratio in a car without Active Steering marketing nomenclature applied to it.

It's not the lack of Active Steering that is the issue, it's the presence of M Servotronic, which as my previous post described, does not have variable ratio, only variable assist. The reason it may be listed as "average 12.5:1" some places, I'm theorizing, is that the ratio will vary slightly though the range due to the geometry of the steering links.
