What is the difference between an Audi Quattro and all-wheel drive?

I am looking to buy a new Audi but I am not sure what the difference is between Quattro and all-wheel drive. Can someone explain the technical differences to me?

Audi Quattro is a specific type of all-wheel drive system designed by Audi. It uses a mechanical center differential to distribute power evenly between the front and rear axles, whereas all-wheel drive systems may use different types of differentials or clutches to do the same thing.

All-wheel drive is a generic term used to describe a drivetrain that sends power to all four wheels of a vehicle. However, the specific design and functionalities of all-wheel drive systems can vary between manufacturers. In Audi's case, Quattro is their proprietary all-wheel drive system that offers superior traction and handling.

One major difference between Quattro and all-wheel drive is the type of power distribution. Audi Quattro has a 40:60 front-to-rear torque bias, meaning the majority of power is sent to the rear wheels for a more sporty and balanced feel. Other all-wheel drive systems may have different torque biases or even variable torque distribution.
