What is the difference between Audi's Quattro technology and other all-wheel drive systems?

I've heard that Audi's Quattro technology is different from other all-wheel drive systems. Can you explain why?

Audi's Quattro technology is unique as it uses a center differential to split power between the front and rear axles, ensuring a more balanced and efficient distribution. This allows for better handling and improved traction, especially in slippery conditions.

Compared to other all-wheel drive systems, Audi's Quattro technology has a power bias towards the rear wheels, giving the car a more sporty and dynamic feel when driving. This system also constantly monitors road conditions and can adjust power to each individual wheel for optimal grip.

One key difference with Audi's Quattro technology is that it has a self-locking center differential, which can transfer torque between the front and rear axles depending on which has the most traction. This allows for improved stability and control on various road surfaces.
