What does a Quattro system refer to in an Audi vehicle?

I am looking to purchase an Audi vehicle, and I keep seeing the term 'Quattro system' mentioned. Can you explain what this refers to and if it's important to consider when choosing a vehicle?

The Quattro system is Audi's signature all-wheel drive technology. It allows for better traction and handling, especially in inclement weather or rough terrain. It is definitely something to consider when choosing a vehicle, especially if you live in an area with harsh weather conditions.

The Quattro system is one of the main selling points of an Audi, as it provides better stability and control on the road. It's definitely worth considering when making your purchase, regardless of where you live.

I have been a loyal Audi customer for years and I can say with confidence that the Quattro system is worth its weight in gold. It gives you a sense of security and confidence while driving, and I highly recommend it.
