Hot Climate vs Cold Climate version?

[Rewted]

     Featured on BIMMERPOST.com

Shopping Canadian inventory I've noticed M4 listing S823A Hot Climate version along with "Canadian Specifications".

Winters get cold here (-30C), should I be looking for 842 Cold Climate or is there such a thing anymore?

I think cold climate is heated seats and heated steering wheel standard. I love both.

As far as I know different settings for the cooling output of the climate control controlled by the IHKA (Integriertes Heizung und Klima automatic).

From the tech docs:

IHKA programming enhanced to produce more cooling output when selected to “hot country”. (Footwell and defrost vents closed to allow more center vent air for maximum cold air.)

I do however see a difference in the part numbers for the cooling fan parts (fan assembly, shroud, ...) it is not clear what the difference is.

In the E82 1 series the two different blower motors were different wattages supposedly (source). Also, with some older BMWs the different climate versions would come with different oil coolers and mechanical/hardware differences.

For the F3x series there is a difference.
Part # 17 42 8 641 963 is 400 Watt
Part # 17 42 8 641 964 is 600 Watt (hot climate version)

I don’t know where I looked earlier but for the F8x I don’t see a difference in part numbers for the fan.

I would expect ‘cold climate’ to come with better insulated hoses to prevent condensation from freezing in the hoses but I don’t see different part numbers for any of the hoses in the F8x.

To give an example take the crankcase vent hose (number 7) where one would expect a difference if there is a difference:



I don’t see different part numbers but on the photo in the link you can see that they are insulated:

Maybe there is no difference for the F8x but then I wonder if this is going to give problems in very cold climates. The ‘cold’ vs ‘hot’ climate is totally new to me

I find it rather odd too. Especially now that I've been browsing current Canadian inventory, all 2018 M4 have been "Hot Climate Version". I've even gone back to check 2016-2017 models with same results. Majority of Canada had a brutal winter this year... you'd think the cars would be cold weather spec.
