How does the Audi A7's Quattro AWD System Work?

I've heard that the Audi A7 comes with a Quattro all-wheel drive system. I'm curious about how it works and why it's considered superior to other AWD systems.

The Quattro AWD system utilizes a center differential that distributes power between the front and rear axles, based on the current driving conditions. It can send up to 70% of power to the front or up to 85% to the rear, giving the A7 enhanced traction and stability on all terrains.

Unlike other AWD systems that rely on a clutch system, the Quattro uses a self-locking center differential, which allows for a more balanced distribution of power. This results in better handling and cornering abilities, especially in slippery or challenging road conditions.
