How does the Audi A4's all-wheel drive system work?

I've heard about the Audi A4's Quattro all-wheel drive system, but I'm not sure how it works. Can anyone explain the technology behind it?

The Audi A4's Quattro system uses a center differential to distribute power between the front and rear wheels, constantly monitoring traction and adjusting power as needed. It's a great system for ensuring grip and stability in all driving conditions.

I've owned an Audi A4 with Quattro for years and have driven through all kinds of weather. Trust me, this system is a game-changer. You'll feel like you have extra sticky tires even in the rain or snow.

Quattro isn't just for tackling tricky weather conditions. It also gives the Audi A4 better handling and cornering abilities, making it a joy to drive on twisty roads. Plus, it helps with acceleration and stability during fast starts.
