How is the Audi A4's quattro all-wheel drive system different than other AWD systems?

I've been researching all-wheel drive systems and have heard a lot about Audi's quattro system. How does it work and what makes it unique compared to other AWD systems on the market?

The quattro all-wheel drive system uses a central differential to distribute torque between the front and rear axles, allowing for better traction and stability on various road conditions. Compared to other AWD systems, this setup allows for a more balanced distribution of power and can handle more extreme driving situations.

One of the main differences with Audi's quattro system is its proactive response, constantly monitoring road conditions and adjusting power distribution to each wheel accordingly. This helps prevent slipping and sliding, making it a top choice for drivers in areas with unpredictable weather.
