How does the Audi A4's quattro system enhance its performance?

I've heard that the Audi A4 has a quattro all-wheel drive system, but I'm not familiar with it. How does this system work and what benefits does it provide in terms of performance?

The Audi A4's quattro system is a permanent all-wheel drive system that distributes power between the front and rear axles to provide maximum grip and traction on all road surfaces. It constantly monitors driving conditions and can send up to 70% of power to the front wheels or up to 85% to the rear wheels for improved handling and stability.

As an Audi A4 owner, I can attest to the fact that the quattro system greatly improves the car's performance, especially in challenging road conditions. I've never had any issues with losing traction or control, even on wet or snowy roads.
