Unless you're putting Winter tyres on the C7, good luck in thinking it will handle any better than the M5 in snow:) It's the wheel/tyre size/compound that's gonna hamper your progress in snow, not AWD vs. RWD. Looking at your photos your M5 has the 20's but you're going for 21's on the C7? The C7 with Summer tyres on that size of wheel will slide around like a bitch in the snow i'm afraid. If swapping purely due to snow performance, you'd have been better off spending £2k & getting a decent winter wheel/tyre combo on the M5.
That said, the AWD of the C7 does have some minor advantage in other road conditions:) Nice car though

I considered going to winter tyres and knew that it would help even to the point of making it OK however the cost was more than £2K (because you need wheels too) and then there's the hassle of swapping back and forth plus you should ideally add some weight in the boot. However, before my M5 I had an S5 with Dunlop Sportmaxx Tyres (OEM). These are ok but really little better than the tyres I have on my M5 (Michelin Pilot Supersport) and yet the S5 was like a bloody snowmobile compared to the M5 in even worse conditions in exactly the same location you can see in the pic.. I don't expect miracles, I realise that the ideal is winter tyres AND 4WD but 4WD is at least better than 2WD on a BMW M5 which can't get traction in a puddle.

Fair enough, but i've had several AWD cars including Audi RS's & the AWD vs RWD difference in snow is negligible as it's power/big wheels & fat tyres that makes the biggest difference. Agree with the other post regarding regular RWD cars being tricky in the snow, but the M5 had a very different RWD diff setup to other BMW's.
Although i've only had my M5 a few months & have yet to encounter snow, it has been out on cold/wet days & driven considerable distances in some of the recent storms & although it does require a slightly different driving approach to the RS's i doubt come snow time the RWD will hamper my progress over an RS on 21's.
Last performance car was a GT-R & that was horrific in the snow due to it's big fat tyres. Agreed the BMW winter package for the M5 is pricey (as are most manufacturers), but winter tyres are available for the M5 20' wheels & tbh if i went the winter tyre route i'd just get some nice aftermarket wheels in which case it's around £2k for the whole package.
Don't get me wrong, if Audi hadn't been so greedy with what they expect customers to pay for an RS then id' have likely been driving a C7 RS6 now, however the closest Audi could get was to offer me a C7 S6 for the same money as my LCI F10 M5. The S6 would have been a stock car with no options whereas i got a built to order M5 with a couple of options for the same money. Bit of a no brainer really:)
Tis a shame though but i'm enjoying a different kind of car/drive for a while & i've had a lot of Audi's over the years so a change is as good as a rest:)
