What is the difference between quattro and all-wheel drive in the Audi A4?

I am considering purchasing a new Audi A4, but I am confused about the different drivetrain options. Can someone explain the difference between quattro and all-wheel drive in the Audi A4?

Quattro is Audi's all-wheel drive system that uses a center differential to distribute power between the front and rear axles. All-wheel drive in the Audi A4 is a less advanced system that primarily delivers power to the front wheels, but can send power to the rear wheels when needed.

Quattro is known for its superior traction and stability, especially in slippery conditions. If you live in an area with harsh weather or enjoy spirited driving, quattro is definitely worth the upgrade. However, if you primarily drive in mild conditions, all-wheel drive may suffice and be a more affordable option.

In terms of performance, quattro is the clear winner. It provides better grip and handling, allowing for faster acceleration and cornering. All-wheel drive in the Audi A4 is more focused on providing extra traction on rough roads or in inclement weather.
