Why do Audi A4 models come with quattro all-wheel drive?

I am considering purchasing an Audi A4 and noticed that all models come equipped with quattro all-wheel drive. Is this a necessary feature and what are its benefits?

Quattro all-wheel drive is a key feature in Audi A4 models. It provides superior traction, stability, and handling, making it a necessary addition for those living in regions with inclement weather.

While not necessary for all drivers, quattro all-wheel drive is a valuable addition for those who enjoy spirited driving. It allows for quicker acceleration and improved cornering capabilities.

One of the main benefits of quattro all-wheel drive is its ability to distribute power to all four wheels, providing better grip and control on slippery surfaces. It also helps enhance fuel efficiency.
