Can someone please take a photo of their rear wheel once it’s turned to show that it works? I have tried to drive in a circle with the front wheels locked then stop and get out. When I look there is no movement in the rear wheels. I don’t think mine is working.

The rear wheel of Integral Active Steering can turn to a maximum of only 3 degrees.
It is not easy to tell the difference of 3 degrees, and it probably won't show in a photo.

It is very difficult to see, even in the mirrors when reversing. Although the 6º becomes obvious when turning lock to lock with a straight edge against a rear wheel pointing at the wheel arch. I guess everyone with the option has had their mate watch from outside the car to see if anything is noticed.

Btw, if it's fitted and not working the dashboard lets you know. As it's safety critical it has a whole load of sensors to make sure all is OK.

For me, the biggest giveaway was the feeling of over-rotation at low speeds on small roundabouts, almost like the back end was slipping. Took me a few hundred miles before I stopped noticing it.

Its extremely noticeable to me using the butt dyno and frankly drives me nuts even though I like it when in tight spaces. I'm not sure how I'll like it in the snow where I tend to be hyper sensitive to what the car is doing (slipping, etc.). That said, you can turn on the setting in iDrive to let the car know you have tire chains on and it will disable the rear wheel steering to get a feel of the car with RWS on and off.

While testing, keep in mind this will only work up until 30mph, over that and the IAS will automatically be turned on.

It would seem to me that 3 degrees would be noticeable if you got out and looked, like a bent wheel or axle. Otherwise it’s a lot of tech for very little movement. And then how would it even be helpful in parking by turning only 1-3 degrees.

Supposed to reduce the turning circle by a metre, can’t say I’ve noticed though but having nothing to compare it to, I wouldn’t.

I have it and it is really easy on roundabouts and tight parking lots. I did a test drive without one year ago so it is difficult to compare.

Subjectively at least it makes the car turn easier. I have never tried to see the rear wheels turning. I had a 6GT (length of a 7 series) and the G05 really handels short corners better.

I didn't need any getting used to. My wife didn't either. She took over the wheel during the holidays, I didn't tell her about the rear wheels and she never mentioned anything.

I did some mountain roads in the alps the last days. Really nice in the corners in sport mode.

It’s definitely noticeable how tighter the turning circle on my G05 with 4WS is compared to my old F15 without. I now wouldn’t get another similar size car without it as it makes a big difference in some of the tiny car parks I need to navigate though to park!

You'll love it in the snow. So much fun and so smooth.

3:00 in this video shows it quite well.

We have it in our car. When you first turn into a corner, you will notice it begins to turn in really soon. However, you will learn to steer a bit later.
It does give the illusion/feeling that the rear is swinging out very slightly when making reasonably sharp turns at 50-60 km/h, but again, you will get used to it.
Pulling off U-Turns and parking manoeuvres with ease is pretty satisfying.

Coming from a smaller X3, IAS made the X5 feel so much smaller in tight spaces. To me, its a must have feature for a vehicle of this size. At higher speeds on tigt turns, the vehicle does seem to be "more on rails" as the rear wheels turn in the same direction as the front as you don't feel the rear is slipping out.
And yes, i have seen the real wheels move when parked and the steering is turned.

[Heavyd]

I was parked, started the car and let someone turn the steering completely to the left and right a few times. I didn't see the rear wheels move. Do they move if the car is not moving?

is this feature available on 2021 models? Is it a separate feature or included in some package?

For M21, not available on xDrive40i and only on M50i with Dynamic Handling Package.

For the M50i it is also combined with air suspension.

[lair12]

Not true, it is a $3650 option on xDrive and $2600 option on M50i.

This is not accurate. IAS (2VH) is not available on the 40i and it is not an option on the M50i. Fore the M50i it is part of the DHP package (maybe where you got the $2,600 from) as well as part of the Air Suspension package ($1,300).

[The J-Man]

Tilt your side mirror down and drive in a tight circle and you can see the wheel move.

[lair12]

Yes, that is what I meant. If can be had on the xDrive if you get the DHP. I took the prior post to imply that you could not get it under any circumstance except on the M50i. Sorry if I misunderstood.

That is exactly what the post meant. IAS and DHP is not available on the 40i xdrive.


Edit: Are you possibly referring to the X6 rather than the X5?
