What is the difference between quattro and e-tron on Audi vehicles?

I am researching Audi vehicles and am interested in their all-wheel drive options. Can anyone explain the differences between quattro and e-tron? Are there any notable performance differences or benefits to either one?

Quattro is Audi's traditional all-wheel drive system that uses a center differential to distribute torque between the front and rear axles. It offers great traction and stability on all road surfaces, making it ideal for handling different weather conditions. On the other hand, e-tron is Audi's electric all-wheel drive system, which uses electric motors to power each individual wheel. This allows for a more dynamic and precise distribution of power, resulting in better acceleration and handling.
