SNOW Mode MG4

Doesn't that screenshot proves that ABS would kick in? Under normal conditions, ABS would not be activated. Snow is not normal conditions. It also talks about braking force exceeding adhesion, causing wheels to lock, which is what happens when you start to skid in the snow and the ABS kicks in.

Personally, I turn all assistance off in snow to maintain maximum control over everything.

You can’t turn off ABS.
I’ve yet to come across any car where the ABS can be switched off.
Everything else can be switched off, but not ABS.

Totally disagree on both comments there is no way the regen would lock the wheels on any MG and ABS does not work until you brake harder than is normal photoshop from MG4 handbook page 192-193 below plus traction control can be disabled if you want to
So when you have a few inch’s of snow on the roads where you are then try snow mode and I bet you you soon back in Eco or Normal mode to get some control back by gently use the accelerator and the brakes I sure you will find

On standard tyres in snow, I can easily see the heaviest (default) regen locking the rears if someone comes off the throttle suddenly.
No problem at all.

Sorry yes, I should have been clear that I turn off everything that can be turned off. Stability/traction control, hill hold etc.

That Sorry to I can’t agree with, under Regen braking, for me it’s not that strong but I’m no expert and perhaps don’t generally drive fast enough.

Traction TCS no use at all in snow I agree.

I think you have read that wrongly it says ABS does nothing until YOUR braking force exceeds normal and then it kicks in to prevent the wheels locking up.

In days gone by good drivers could and did pump the brake pedal very very quickly simulating what ABS does today to avoid the vehicle skidding.
Please when ever you have chance do try Snow mode, I can tell you I did not find any benefit from it at all and switched it off then back to normal mode highest Regen setting and gently use of the accelerator was much better IMHO.

I really can't understand why so many are advocating regen for braking in slippery weather. A tyre can only accept so much braking force before that force overcomes friction and you skid. For any given total deceleration, brakes spread the force over 4 wheels whereas regen only applies it to two, making it more likely that they will skid.
 
Hi Tom here is what I post in December last year about Snow mode
Les

Tried the Snow mode setting this morning what does it do you might ask well to quote Paul Daniels “ Not A Lot “ all that appear to happen was it took the brake re gen from high to low, lower than low setting which did surprise me really as the re gen was zero or as near as dam, plus the throttle appeared to hold itself at a very low level which is what you would want in snow but with no re gen on the brakes the setting of which I could not change while in snow mode, it meant you have to use the brake lightly to keep control I played around with it for 5-10 minutes and then put the car back in default of normal with high regeneration on the brakes may be I was doing something wrong but I did not feel to happy in snow mode, pictures below show why I tried Snow Mode awoke this morning at the cottage in the lakes we use to about 4-6 inch’s of the white stuff under foot and tyres

Snow mode will turn regen off because regen only initially brakes one wheel if you have one motor running through a differential, which could cause the car to spin if one wheel skids.
You're best off using the mechanical (hydraulic) brakes in snow as they will brake all the wheels as required.

If you haven't fitted winter/snow tyres don't go out in the snow.

A million times this!

I got my DSG automatic Golf just before one of the worst winters for a long time. The bloody thing was like Bambi on an ice-rink, and the usual tricks with manual gear-shift cars simply did not work. Although in theory you can put a DSG into manual and select any gear you like, my Golf refused even to try to pull away in second in snow or ice. It simply wouldn't let me select the gear. I was in despair.

Then I fitted winter tyres. Bambi on an ice-rink suddenly turned into a Landrover. It would go anywhere. It even became less vital to clear my drive as the car would simply drive over it, and even drive over the piles of snow the council snow-plough had left right along the pavement. I've changed my tyres every November and April ever since then and consider it money well spent. Anyway, you can only wear out one set at a time, and the only extra cost is the up-front purchase and then getting them changed over at the garage.

I've heard people speak well of all-season tyres for the MG4 and I'll think about exactly what to do when this November comes round, but something is going to be done. I'm completely finished with trying to negotiate snow and ice by trick driving when the solution is right there in the tyres.

I don’t think that I would use snow mode. Happy in eco with medium regen for snow. Now for black ice 🥶. I too drove for over 20 years in the Scottish highlands and always found it a good idea to have a little spin in the first snows to hone my reactions e. g. No slamming on the brakes, highest gear etc
 
There's a difference. Snow tyres have studs and can only be used at restricted speed. They are also not suitable to drive on bare tarmac. Winter tyres have no studs and achieve their function with a combination of a softer rubber formulation and a different tread pattern. They are fine at normal speeds and on clear roads. In 2020 I kept mine on all summer as the garages were working short hours and I wasn't driving far.

The downside of using winter tyres in the summer is faster tyre wear and more tyre noise.

Oops, I meant to say "Winter" tyres. 🫢
