Snowking,not to be pedantic,but i don't think audi ever made a RWD model.
The thing about driving in snow is get a pair of snow tyres on your driven wheels,ideally all 4.
Unless the depth of snow makes your car bottom out,you will never get stuck,no matter what you are driving,Unless it's black or sheet ice.
What's the usual cars you see spinning their wheels and going sideways,it's bmw's and mercs because they have tarmac tyres with no grip in the snow.
Trust me,anyone who is nervous about getting stuck in snow,buy some snow/winter tyres and put them on before the first snow.
