What does the 'quattro' in Audi vehicles refer to?

I've heard that Audi vehicles have a special feature called 'quattro', but I'm not sure what it does or why it's significant. Can anyone explain?

The 'quattro' in Audi vehicles refers to the brand's signature all-wheel drive system. It distributes power to all four wheels, providing better traction and handling in various driving conditions.

Audi's 'quattro' system has been around since 1980 and has become a defining feature of the brand. It's especially useful for driving in inclement weather or on uneven terrain.

Just like how every Audi model has a unique design, each one also has a specific 'quattro' system tailored to its capabilities. This system is continuously evolving and improving, making Audi vehicles even more impressive.
