What is the meaning of the Audi A6's 'quattro' feature?

I have heard that the Audi A6 has a feature called 'quattro', but I am not sure what it does. Can someone explain its purpose?

Hi Janet, 'quattro' is a feature that provides all-wheel drive for the Audi A6. It helps with traction and handling, especially in slippery conditions.

Hey Janet, 'quattro' is a great feature that gives the Audi A6 better stability and control on the road, even in challenging driving situations.
