X3 Steering with MSports Pack

My 2012 X5 3.5 has the MSports Pack option. When I engage Sports/Sports+, I can feel the steering effort tighten, but the steering ratio remains the same. Is this normal or should it have variable ration steering which isn't working on my vehicle?

Did you get the dynamic handling package? That includes the variable steering. If you didn't get that package, then you don't have it.

Yes, I have the dynamic handling package as well. As I previously indicated, switching to sports or sports+ only increased the steering effort, not the steering ratio.

Just curious what is Steering Ratio?

Someone can correct me if I'm wrong, but I don't think the steering ratio changes from one mode to another, I think it only changes depending on your speed. I think this amount of change is the same regardless if you're in normal or sport or anything else.

The Variable Sport Steering option, in the DHP package, changes the steering ratio according to the angle/position of your steering wheel, not your vehicle speed.

It doesn't change in different modes.
So, it's active in all modes.

The servotronic power steering is the feature that tighten the steering feel when you change to spot/sport+ modes.

So this brings me back to my initial question. Should my X3 with M-Sports pack and DHP have variable sports steering which alters steering ratio?

It changes the steering effort.
