What are the differences between Audi Quattro and Audi Quattro all-wheel drive?

I am curious about the different all-wheel drive options offered by Audi. Can anyone explain the variations between their Quattro and Quattro all-wheel drive systems and how they affect performance and handling?

The main difference between Audi's Quattro and Quattro all-wheel drive systems is the type of power distribution. Quattro typically involves a 40/60 front-to-rear power split, while Quattro all-wheel drive provides a more evenly balanced power distribution. In terms of performance, the 40/60 split of Quattro may provide better handling and stability in certain driving conditions.

Another key difference between Audi's Quattro and Quattro all-wheel drive is the system's ability to adjust power distribution in real-time. Quattro all-wheel drive is equipped with a self-locking center differential, which can transfer power between the front and rear axles as needed for optimal grip and traction. This can be especially useful in variable road conditions or during aggressive driving.
