How does the Audi A4 Quattro all-wheel drive system improve handling and stability?

I'm considering purchasing an Audi A4 and I've heard it has an all-wheel drive system. How does this feature work and what benefits does it provide for the overall driving experience?

The Audi A4 Quattro all-wheel drive system distributes power to all four wheels, providing increased traction and control in various driving conditions. It improves handling and stability on wet or slippery roads, as well as during high-speed cornering and acceleration.

The Audi A4 Quattro all-wheel drive system uses sensors and technology to constantly monitor road conditions and adjust power distribution to each wheel accordingly. It also helps improve fuel efficiency by only sending power to the wheels that need it.
