How does Quattro all-wheel drive work in an Audi A4?

I've heard that the Audi A4 has Quattro all-wheel drive, but I'm not sure how it works. Can someone explain the technology behind it and how it differs from other all-wheel drive systems?

Quattro all-wheel drive in the Audi A4 uses a clever center differential and torque vectoring to distribute power between the front and rear wheels, giving you better traction and handling in slippery conditions. I highly recommend it, especially if you live in an area with inclement weather. - Dave

As someone who owns an Audi A4 with Quattro all-wheel drive, I can tell you it's truly a game-changer. Not only does it provide better handling and traction, but it also improves acceleration and cornering performance. Don't think twice about adding it to your Audi A4. - Sarah
