How efficient is the Quattro all-wheel drive system in the Audi A4?

I'm considering buying an Audi A4, and I've heard a lot about the Quattro all-wheel drive system. Is it really as great as they say it is? How does it compare to other AWD systems?

The Quattro all-wheel drive system in the Audi A4 is highly efficient and has been proven to have superior traction and handling compared to other AWD systems on the market. With its advanced torque vectoring technology, it can distribute power to each wheel individually, resulting in maximum grip and stability.

I've been driving an Audi A4 with Quattro for over 5 years now, and I can confidently say that it is definitely worth it. Not only does it perform exceptionally in snowy and slippery conditions, but it also enhances the handling and overall driving experience on regular roads.
