I am genuinely astonished by how well my quattro is in the snow and on ice. I drove up a hill, tarmac covered in an inch of snow&ice that a land rover S111 was struggling to get up. The ESP light in the dash flashes and you can fell the power being shifted around and it just keeps going! The back slides around a bit, you get a bit of oversteer and a bit of understeer into and out of corners, but the car seems to sort this out for you! its awesome.
