Well here it is, 300 hp high torque RWD will be extremely tail happy. 4WD is not.
And comparing to ICE, winter driving wise, I'm thinking this weight sort of helps in in some situations and hurts you in rest. Mainly you might get going a bit better and feel more planted in snowy and slushy conditions. But when you are sliding or trying to stop the car that weight is your enemy.
My recipe for actual winter driving: 1) winter tires 2) 4WD
And same for fun: 1) winter tires 2) RWD
All in all, you will get by. But some people just hate how RWD feels in winter, so if thats a new and frightening thing to you, maybe reconsider. And to my experience, electric cars tend to be just marginally better in these conditions than ICE. Fanatics tend to tell you otherwise. If you you need 4WD with ICE, you do so with electric car as well.
Yeah here I am changing our G30 530e (RWD) to i4 M50 with mixed feelings considering winter driving. Less fun, more performance.
