Others have said the same, not tired it though we don’t use her car for longer journeys typically. Assume it would conserve the battery to the best places across the journey.

Ordered yesterday X1 30e Msport with Msport pro package, spacesilber grey.
Estimated delivery 3-4 months.

What happens if battery gets empty and I am stucked 20-30kms in mountains in snow. Will 4x4 work all the way anyway? Won’t it stop working at some point? How does it charge in such conditions if it has to be engaged.

[MontyB1]

It’s unclear, it seems to have a fairly large reserve to allow for at least 4wd when you set off, after that just ICE. But there has to be a point in certain conditions it goes completely but info is sketchy on absolute specifics.

It’s been discussed across many threads before with no definitive answer exactly how far or for how long or in what conditions.

I would imagine (pure speculation) that the regen is pretty smart in these circumstance.

On a long journey in maintain battery mode, it keeps the battery about the same level.

So my thinking is, if it has the capacity to manage the battery like this, then it may be able to use regen even more when battery is indicated zero, as the car is obviously using fuel at these times.

If that's the case, it may be able to maintain AWD for as long as it is still driving on fuel.
It would likely be at the expense of performance and economy, but who cares if you are driving in snow with zero battery.

Pure speculation - would love to know more.

If I'm not mistaken, the battery takes energy from the combustion engine to make the 4x4 work even if the charge is at 0%.
My mother has an Evoque P300e and I guarantee you that with a flat battery the 4x4 worked in the snow without any problem.

I've read somewhere that U11 is using rear wheels to charge the battery, so they would have to spin in order to charge it. If car is stuck in snow and battery is empty (not empty on driver's display, but really empty) then I think it is bye bye to 4x4 on this model. If I understand it correctly, it is not like on Hondas or other cars, where petrol can internally charge battery, this does not happen in this model. Correct?

In U11 plug in there is no drive shaft between petrol engine in front and rear axle, opposed to 23i for example, so that also makes me think that it won't work once battery is totally empty.

Probably it is not such a big deal, because car can make some distance on 4x4 if there is some backup charge in battery (after it displays 0 charge to the driver), but once it is completely depleted you can be screwed.

On BMWs the engine / ICE doesn't charge the battery it's only from regen / braking etc. so you are right. Ultimately if the car is stuck for example it will run out. The view is the reserve is fairly large so that is unlikely and the car can add enough back into the reserve and not the actual usable part of the battery as that stage.

All seems in theory though and in reality only the BMW engineers know exactly what's happened which the likely find in some lab / winter testing.

The Evoque is different. It has a generator to charge the battery if needed and quite quickly at the expense of fuel consumption. As it has proper off road capability this avoids getting stranded in deep snow, mud, rivers, sand etc. The U11 is really a street car and 4x4 for traction when needed in less serious situations.

Also worth noting that modern EV batteries can be kept stored for very long periods with minimal loss of charge.

And once moving they can be incredibly efficient at charging with regen. Something like 30% of a typical EV range is from braking regen.
For example, a Taycan can put enough juice in the battery in 3 seconds braking to drive about a km.

When you see zero charge on the X1 there is actually quite a buffer.
14.2 kWh is useable out of 16.3 kWh capacity.

And my betting is the car will be doing all it can to maintain this buffer from regen when the battery is low and AWD is needed.

Ideally, if your battery is on zero and it's snowing. Drive downhill and brake a lot

In this test they explain that "There is no physical connection between the two engines, no transmission shaft. But despite this, when driving you never notice this absence. The interaction between the two units is managed electronically, to ensure ensure that both work in unison, when needed, to always guarantee maximum traction in case of need. For this reason, the battery never runs down completely, to allow the car to rely on traction whole whenever you need it.
[...]
But the real added value of this system is given by the fact that nothing needs to be done to activate it. It does everything by itself, leaving the driver to concentrate on driving."

Therefore, the battery is probably charged anyway if four-wheel drive is needed; I don't think they would risk leaving us "only" with front wheel drive.

In which package there is aid which ensures plug-in uses electricity in city and petrol on highway and keep charge for when it is needed based on navigation route? In one dealership they told me I need Driving Assistant Professional for this, but is it right? Wouldn't Driving Assistant and Driving Assistant Plus be satisfactory for this?

[Taylor66]

I've been driving a 330e for around 4 years and I found that if you put a destination in the satnav, it does the clever stuff for you conserving battery for the most efficient areas (City driving) etc. But cleverer than that if you have a regular route your car seams to learn that without you needing to use the satnav.

It is standard, you don’t need any upgraded systems, just put your destination in the nav and the car sorts it. If you put your final destination to home and ad where you are going as a stop then the car will save some electric for the return part of the journey.

My wife has just started to notice that on her car.
The satnav has started guessing if she takes a regular route - even without using any destination on the satnav.
I was sceptical till we went out this morning - and it guessed (correctly) where we were heading.

Clever stuff.
Assume it's AI based magic?
