How does Audi's Quattro all-wheel drive system work in the A3?

I'm interested in purchasing an Audi A3 but I've heard a lot about their Quattro all-wheel drive system. Can someone explain how it works and its benefits specifically for the A3 model?

Audi's Quattro all-wheel drive system uses a mechanical power-splitting differential to distribute power between front and rear axles. This not only improves traction and handling in various road conditions but also enhances the overall driving experience.

One of the biggest benefits of Audi's Quattro all-wheel drive system in the A3 is its ability to continuously adjust power delivery to each wheel in real-time. This results in improved stability and cornering, making it ideal for both daily driving and sportier excursions.

I've found that the Quattro all-wheel drive system in the A3 provides a noticeable improvement in fuel efficiency compared to traditional all-wheel drive systems. This is due to its intelligent torque distribution which reduces unnecessary power loss and boosts fuel economy.
