The only way to option IAS on M50i is optioning ZDH Dynamic Handling Package. Haven't seen any changes or reductions to ZDH package components.

MY19-20 40i and 50i SAVs, IAS was an option in combination with air suspension or included with ZOR Off-Road package. IAS was removed for MY21 40i SAVs.

MY20-21 M50i SAV, IAS is as an option in combination with air suspension or ZDH Dynamic Handling Package.

2020 40i in the States was available as an option within DHP package as well.

Ja, exactly MY20 X7 40i with DHP.

My reply to the forum member was in context to his inquiry regarding USA X5 45e and 40i where DHP isn't an option.

I don't get the criticism either. The IAS on my m50i is one of my top features. It changes the car completely IMO.

Didn't know that bit about alignment - thanks!

I want the BMW handling. But My God, could they make it any more complicated?? And to boot, it sounds like its plain impossible to get some of these options on some/all vehicles at this time.
Combined with other options being deleted (chip shortages or whatever) I am SO glad I am not ready to spring for a new X5 yet. Going to run my E70 X5 50i for much longer while my wife shops for a new car (BEV) to replace her really dependable and great all-around e90 328...

I have driven an X5 45e M Sport w/o IAS and then ordered an X5 45e M Sport with IAS. So weight, model, suspension all the same. Actually even the wheels were the 20 inch Runflat 740M in both cases, except mine currently has winter rubber on them.

The steering feel is pretty similar (little feedback, but comparable steering weight). Quick turns at low speeds feel more agile, and quick highway lane changes have a bit less body roll. The difference in turn radius is significant. The regular 45e has around the same nasty turn radius as my previous M5 which is pretty unpleasant in European. With IAS, it's around 1m less and there are a few parking garages and 180 turns in my driving where this is a refreshing change.

The steering doesn't feel a lot lighter or more artifical - which I had feared could happen. If at all, it feels a bit lighter, but not by much. And so far I have had no surprises - I was immediately comfortable. The early E60 IAS was a different beast - and not in a good way.

Highly recommended for those who can get it and have to deal with European sized parking lots... In regions where every 3rd car in the lot is an F-150, you can probably skip the option.

I wonder if BMW would follow Mercedes and offer rear steering up to 10 degrees (EQS). It looks quite remarkable from the outside.
It reduces the turning circle up to 2m for the EQS.

I have ZOR OFF-ROAD Package in my MY2019 M40i. Is it possible to add IAS and/or DHP aftermarket wise. What I am trying to ask is dose the hardware conflict between Electronic rear differential lock and the IAS? Thanks a lot!

[Heavyd]

I wonder when it will become available again. I have a 50e on order and I couldn't take iAS, my 45e has iAS. I really hope it will become available before my car goes in production in July.
It was almost a dealbreaker but in the end I took the risk. Hopefully I won't regret the 50e without iAS.

I don’t believe there is a conflict with the hardware. I have researched this myself and you’d need to replace the front EPS steering gear, as well as add the one for the rear axle and run the wiring to it. Install wise it actually looks pretty simple, but my biggest concern with it is finding someone to do a proper alignment after install and then each time afterwards.

Thank you so much! This has solved my biggest concern as I kept seeing that regulated rear axle differential lock might occupy the position of real IAS. I do have some local garage resource to do the retrofit and do the wiring staff. In terms of the proper alignment, do you mean by four wheels alignment after the installation? Thanks

Yes, the four wheel alignment. I have heard that some independent shops and even the dealers can really mess things up trying to do the alignment which is a turn-off for me wanting to do the retrofit, along with not wanting to mess anything up while under warranty.
