What features does the Audi Q5 come with for optimal winter driving?

I am planning on buying an Audi Q5, but I live in a region with harsh winter conditions. What are the must-have features for optimal winter driving and what models come equipped with them?

The Audi Q5 comes with several features that make it suitable for winter driving. The first and most important is the Quattro all-wheel-drive system, which provides better traction and stability on snowy or icy roads.
