Car appreciation... the aesthetics, the engineering, etc

No. But I've driven shit rental cars in the snow with normal tyres without chains and I'm still alive to post irrelevant opinions online.

They do snow and ice much better there than in the UK. I wouldn't worry.

Just find a big car park to have fun in.

Yes but only SE UK levels of snow... Put it in snow mode (which allows some slip before TC kicks in) and take it easy. Unless you’re trying to slide around obvs!

Depending where you are going or driving through (Switzerland)as you might have to have winter tyres.

BMW can have issues as the cars are rear wheel drive and low weight over the rear wheels. Why not book a skid pan course and get a little practice.

You’ll need winter tyres as well I believe- they’re mandatory for certain times of year.

Last snow storm here - hard shoulder leading out of Belfast (M2 ) on the hill section was strewn with BMWs. Other cars seemed to manage much better but that does not take into account driving skill - or lack of it in poor conditions.

I drove our Volvo v90 to the Swiss alps last year with standard tires. Zero issues. Admittedly it’s front wheel drive but you could have driven an M4 up to our chalet without much bother. Roads were cleared very well.

2 trips to Morzine last winter in my 340i . Winter tyres work.
Practice putting your chains on , nothing worse than kneeling on the road in the snow at night trying work out how they go on...
Snow socks on the front if you want to be double safe but watch out they shred quickly on any bit of tarmac.
In reality only needed chains once in all the years I have driven and that was to get to Ste Foy after a big dump.
A lot depends on where you going , eg Morzine is low and the roads will nearly always be clear unless you are arriving v.late at night in a storm , then a small risk the snow ploughs haven’t been out. On the other hand the road up to Avoriaz when it’s dumping can be completely different.

What size wheels have you got? I e got a set of lightly used winters from my old 130i you could have cheeeeeeap.
