What does the 'quattro' feature in the Audi A6 do?

I'm considering purchasing an Audi A6 and I keep seeing references to the 'quattro' feature. What exactly does it do and is it worth the extra cost?

The 'quattro' feature in the Audi A6 is a permanent all-wheel drive system that distributes power to all four wheels for enhanced grip and control on the road. This can be especially helpful in slippery or challenging driving conditions.

In my experience, the 'quattro' feature is definitely worth the extra cost. I live in an area with harsh winters and the added stability and traction from having all-wheel drive has made a noticeable difference in my driving experience.

If you live in an area with mostly dry or mild weather, the 'quattro' feature may not be as necessary. However, it can still provide added peace of mind and improved handling in unexpected situations.
